  Welcome to the Huberman Lab Podcast where we discuss science and science-based tools for everyday life.

• 0:09Andrew D. Huberman?

  I'm Andrew Huberman and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. Today, I have the pleasure of introducing Dr. Lex Fridman as our guest on the Huberman Lab Podcast. Dr. Friedman is a researcher at MIT specializing in machine learning, artificial intelligence, and human-robot interactions. I must say that the conversation with Lex was, without question, one of the most fascinating conversations that I've ever had, not just in my career, but in my lifetime. I knew that Lex worked on these topics, and I think many of you are probably familiar with Lex and his interest in these topics from his incredible podcast, The Lex Fridman Podcast. If you're not already watching that podcast, please subscribe to it, it is absolutely fantastic.

• 0:53Andrew D. Huberman?

  But in holding this conversation with Lex, I realized something far more important. He revealed to us a bit of his dream, his dream about humans and robots, about humans and machines, and about how those interactions can change the way that we perceive ourselves and that we interact with the world. We discuss relationships of all kinds, relationships with animals, relationships with friends, relationships with family, and romantic relationships. And we discuss relationships with machines, machines that move and machines that don't move, and machines that come to understand us in ways that we could never understand for ourselves, and how those machines can educate us about ourselves.

• 1:35Andrew D. Huberman?

  Before this conversation, I had no concept of the ways in which machines could inform me or anyone about themselves. By the end, I was absolutely taken with the idea, and I'm still taken with the idea, that interactions with machines of a very particular kind, a kind that Lex understands and wants to bring to the world, can not only transform the self, but may very well transform humanity. So whether or not you're familiar with Dr. Lex Fridman or not, I'm certain you're going to learn a tremendous amount from him during the course of our discussion, and that it will transform the way you think about yourself and about the world. Before we begin, I want to mention that this podcast is separate from my teaching and research roles at Stanford.

• 2:17Andrew D. Huberman?

  It is, however, part of my desire and effort to bring zero cost to consumer information about science and science-related tools to the general public. In keeping with that theme, I'd like to thank the sponsors of today's podcast.

• 4:20Andrew D. Huberman?

  And now, my conversation with Dr. Lex Fridman.

• 4:24Lex Fridman?

  We meet again.

• 4:25Andrew D. Huberman?

  We meet again. Thanks so much for sitting down with me. I have a question that I think is on a lot of people's minds, or ought to be on a lot of people's minds. Because we hear these terms a lot these days, but I think most people, including most scientists, and including me, don't know really what is artificial intelligence? And how is it different from things like machine learning and robotics? So if you would be so kind as to explain to us, what is artificial intelligence? And what is machine learning?

• 5:04Lex Fridman?

  Well, I think that question is as complicated and as fascinating as the question of what is intelligence? So I think of artificial intelligence first as a big philosophical thing. Pamela McCordick said AI was

• 5:25Lex Fridman?

  AI was the ancient wish to forge the gods, or was born as an ancient wish to forge the gods. So I think at the big philosophical level, it's our longing to create other intelligent systems, perhaps systems more powerful than us. At the more narrow level, I think it's also a set of tools that are computational, mathematical tools to automate different tasks. And then also, it's our attempt to understand our own mind. So build systems that exhibit some intelligent behavior in order to understand what is intelligence in our own selves. So all those things are true. Of course, what AI really means is a community,

• 6:09Lex Fridman?

  as a set of researchers and engineers, it's a set of tools, a set of computational techniques that allow you to solve various problems. The, there's a long history that approaches the problem from different perspectives. What's always been throughout one of the threads, one of the communities goes under the flag of machine learning, which is emphasizing in the AI space, the, the task of learning. How do you make a machine that knows very little in the beginning, follow some kind of process and learns to become better and better in a particular task? What's been most very effective in the recent about 15 years is a set of techniques that

• 6:54Lex Fridman?

  fall under the flag of deep learning that utilize neural networks. What neural networks are, are these fascinating things inspired by the structure of the human brain very loosely, but they have, it's a network of these little basic computational units called neurons, artificial neurons. And they have, these architectures have an input and an output. They know nothing in the beginning and they're tasked with learning something interesting. What that something interesting is usually involves a particular task. The, there's a lot of ways to talk about this and break this down. Like one of them is how much human supervision is required to teach this thing.

• 7:38Lex Fridman?

  So supervised learning, this broad category is the, the neural network knows nothing in the beginning and then it's given a bunch of examples of, in computer vision, that would be examples of cats, dogs, cars, traffic signs. And then you're given the image and you're given the ground truth of what's in that image. And when you get a large database of such image examples where you know the truth, the, the neural network is able to learn by example. That's called supervised learning. The question, there's a lot of fascinating questions within that, which is how do you provide the truth? When you've given an image of a cat.

• 8:20Lex Fridman?

  How do you provide to the computer that this image contains a cat? Do you just say the entire image is a picture of a cat? Do you do what's very commonly been done, which is a bounding box? You have a very crude box around the cat's face saying this is a cat? Do you do semantic segmentation? Mind you, this is a 2D image of a cat. So it's not a... The computer knows nothing about our three-dimensional world. It's just looking at a set of pixels. So semantic segmentation is drawing a nice, very crisp outline around the cat and saying that's a cat. That's really difficult to provide that truth. And one of the fundamental open questions in computer vision is, is that even a good representation of the truth?

• 9:03Lex Fridman?

  Now, there's another contrasting set of ideas. Their attention, they're overlapping, is what's used to be called unsupervised learning, what's commonly now called self-supervised learning, which is trying to get less and less and less human supervision into the task. So self-supervised learning is more... It's been very successful in the domain of language models, natural language processing, and now more and more is being successful in computer vision tasks. And what's the idea there is let the machine, without any ground-truth annotation, just look at pictures on the internet or look at text on the internet

• 9:47Lex Fridman?

  and try to learn something generalizable about the ideas that are at the core of language or at the core of vision. And based on that, we humans at its best like to call that common sense. So we have this giant base of knowledge, on top of which we build more sophisticated knowledge. We have this kind of common sense knowledge. And so the idea with self-supervised learning is to build this common sense knowledge about... What are the fundamental visual ideas that make up a cat and a dog and all those kinds of things without ever having human supervision?

• 10:25Lex Fridman?

  The dream there is, you just let an AI system that's self-supervised run around the internet for a while, watch YouTube videos for millions and millions of hours, and without any supervision, be primed and ready to actually learn with very few examples, once the human is able to show up. We think of children in this way, human children, is your parents only give one or two examples to teach a concept. The dream with self-supervised learning is that would be the same with machines, that they would watch millions of hours of YouTube videos and then come to a human and be able to understand when the human shows them, "This is a cat." Remember, this is a cat.

• 11:10Lex Fridman?

  They will understand that a cat is not just a thing with pointy ears, or a cat is a thing that's orange, or is furry. They'll see something more fundamental that we humans might not actually be able to introspect and understand. Like, if I asked you what makes a cat versus a dog, you wouldn't probably not be able to answer that, but if I showed you, brought you a cat and a dog, you'd be able to tell the difference. What are the ideas that your brain uses to make that difference? That's the whole dream with self-supervised learning, is it would be able to learn that on its own, that set of common sense knowledge that's able to tell the difference. And then there's like, a lot of incredible uses of self-supervised learning, very weirdly

• 11:55Lex Fridman?

  called self-play mechanism. That's the mechanism behind the reinforcement learning successes of the systems that won't go at AlphaZero, that won't chess.

• 12:08Andrew D. Huberman?

  Oh, I see, that play games.

• 12:10Lex Fridman?

  That play games.

• 12:11Andrew D. Huberman?

  Got it.

• 12:12Lex Fridman?

  So the idea of self-play, this probably applies to other domains than just games, is a system that just plays against itself. And this is fascinating in all kinds of domains, but it knows nothing in the beginning, and the whole idea is, it creates a bunch of mutations of itself, and plays against those versions of itself. And the fascinating thing is, when you play against systems that are a little bit better than you, you start to get better yourself. Like, learning, that's how learning happens. That's true for martial arts, it's true in a lot of cases. Where you want to be interacting with with the systems that are just a little better than you. And then through this process of interacting with systems just a little better than you,

• 12:58Lex Fridman?

  you start following this process where everybody starts getting better and better and better and better, until you are several orders of magnitude better than the world champion in chess, for example. And it's fascinating because it's like a runaway system. One of the most terrifying and exciting things that David Silver, the creator of AlphaGo and AlphaZero, one of the leaders of the team, said to me is they haven't found the ceiling for AlphaZero. Meaning, it could just arbitrarily keep improving. Now, in the realm of chess, that doesn't matter to us, that it's like, it just ran away with the game of chess. Like, it's like, just so much better than humans. But the question is, if you can create that in the realm

• 13:42Lex Fridman?

  that does have a bigger, deeper effect on human beings, on societies, that can be a terrifying process. To me, it's an exciting process if you supervise it correctly. If you inject, if what's called value alignment. You make sure that the goals that the AI is optimizing is aligned with human beings and human societies. There's a lot of fascinating things to talk about within the

• 14:11Lex Fridman?

  specifics of neural networks and all the problems that people are working on. But I would say the really big, exciting one is self-supervised learning, where trying to get less and less human supervision,

• 14:25Lex Fridman?

  less and less human supervision of neural networks. And also, just a comment, and I'll shut up. No, please keep going. I'm learning. I have questions, but I'm learning, so please keep going. So that, to me, what's exciting is not the theory, it's always the application. One of the most exciting applications of artificial intelligence. Specifically, neural networks and machine learning is Tesla Autopilot. So these are systems that are working in the real world. This isn't an academic exercise. This is human lives at stake. This is safety critical. These are automated vehicles. Autonomous. Semi-autonomous. We want to be. Okay. We've gone through wars on these topics. Semi-autonomous. Semi-autonomous.

• 15:06Lex Fridman?

  So even though it's called FSD, full self-driving, it is currently not fully autonomous, meaning human supervision is required. So human is tasked with overseeing the systems. In fact, liability-wise, the human is always responsible. This is a human factor psychology question, which is fascinating. I am fascinated by the whole space, which is a whole nother space of human-robot interaction, when AI systems and humans work together to accomplish tasks. That dance, to me, is one of the smaller communities, but I think it will be one of the most important open problems

• 15:49Lex Fridman?

  once they're solved, is how do humans and robots dance together? To me, semi-autonomous driving is one of those spaces. So for Elon, for example, he doesn't see it that way. He sees semi-autonomous driving as a stepping stone towards fully autonomous driving. Like, humans and robots can't dance well together. Like, humans and humans dance and robots and robots dance. Like, we need to, this is an engineering problem. We need to design a perfect robot that solves this problem. To me, forever, maybe this is not the case with driving, but the world is going to be full of problems where it's always humans and robots have to interact. Because I think robots will always be flawed,

• 16:33Lex Fridman?

  just like humans are going to be flawed, are flawed. And that's what makes life beautiful, that they're flawed. That's where learning happens, at the edge of your capabilities. So you always have to figure out how can flawed robots and flawed humans interact together such that they, like, the sum is bigger than the whole, as opposed to focusing on just building the perfect robot. So that's one of the most exciting applications, I would say, of artificial intelligence to me is autonomous driving and semi-autonomous driving. And that's a really good example of machine learning because those systems are constantly learning.

• 17:16Lex Fridman?

  And there's a process there that maybe I can comment on. Andre Karpati, who's the head of Autopilot, calls it the data engine. And this process applies for a lot of machine learning, which is you build a system that's pretty good at doing stuff. You send it out into the real world. It starts doing the stuff and then it runs into what are called edge cases, like failure cases, where it screws up. You know, we do this as kids, that, you know. We do this as adults. We do this as adults, exactly. But we learn really quickly. But the whole point, and this is the fascinating thing about driving, is you realize there's millions of edge cases. There's just like weird situations that you did not expect.

• 18:00Lex Fridman?

  And so the data engine process is you collect those edge cases and then you go back to the drawing board and learn from them. And so you have to create this data pipeline where all these cars, hundreds of thousands of cars are driving around, and something weird happens. And so whenever this weird detector fires, it's another important concept. That piece of data goes back to the mothership for the training, for the retraining of the system. And through this data engine process, it keeps improving and getting better and better and better and better. So basically, you send out a pretty clever AI systems out into the world and let it find the edge cases.

• 18:44Lex Fridman?

  Let it screw up just enough to figure out where the edge cases are and then go back and learn from them and then send out that new version and keep updating that version. Is the updating done by humans? The annotation is done by humans. So you have to. The weird examples come back, the edge cases, and you have to label what actually happened in there. There's also some mechanisms for automatically labeling, but mostly, I think you always have to rely on humans to improve, to understand what's happening in the weird cases. And then there's a lot of debate. And that's the other thing. What is artificial intelligence? Which is a bunch of smart people having very different opinions about what is intelligence.

• 19:29Lex Fridman?

  So AI is basically a community of people who don't agree on anything.

• 19:33Andrew D. Huberman?

  Yeah, it seems to be the case. You know, first of all, this is a beautiful description of terms that I've heard many times among my colleagues at Stanford, at meetings, in the outside world. And there are so many fascinating things. I have so many questions. But I do want to ask one question about the culture of AI, because it does seem to be a community where, at least as an outsider, where it seems like there's very little consensus about what the terms and the operational definitions even mean. And there seems to be a lot of splitting happening now of not just supervised and unsupervised learning, but these sort of intermediate conditions where machines are autonomous, but then go back for more instruction, like kids go home from college during the summer and get a little, you know, mom still feeds them,

• 20:16Andrew D. Huberman?

  then eventually they leave the nest kind of thing. Is there something in particular about engineers or about people in this realm of engineering that you think lends itself to disagreement?

• 20:29Lex Fridman?

  Yeah, I think, so first of all, the more specific you get, the less disagreement there is. So there's a lot of disagreement about what is artificial intelligence, but there's less disagreement about what is machine learning, and even less when you talk about active learning or machine teaching or self-supervised learning. And then when you get into like NLP, language models, or transformers, when you get into specific neural network architectures, there's less and less and less disagreement about those terms. So you might be hearing the disagreement from the high-level terms. And that has to do with the fact that engineering, especially when you're talking about intelligent systems, is a little bit of an art and a science.

• 21:10Lex Fridman?

  So the art part is the thing that creates disagreements. Because then you start having disagreements about...

• 21:21Lex Fridman?

  How easy or difficult a particular problem is. For example, a lot of people disagree with Elon how difficult the problem of autonomous driving is. And so, but nobody knows. So there's a lot of disagreement about what are the limits of these techniques. And through that, the terminology also contains within it the disagreements. But overall, I think it's also a young science that also has to do with that. So like, it's not just engineering, it's that artificial intelligence truly as a large scale discipline where it's thousands, tens of thousands, hundreds of thousands, people working on it, huge amounts of money being made, that's a very recent thing. So we're trying to figure out those terms.

• 22:06Lex Fridman?

  And of course, there's egos and personalities and a lot of fame to be made, you know, like the term deep learning, for example. Neural networks have been around for many, many decades, since the 60s, you can argue since the 40s. So there was a rebranding of neural networks into the word deep learning, term deep learning, that was part of the reinvigoration of the field, but it's really the same exact thing.

• 22:32Andrew D. Huberman?

  I didn't know that. I mean, I grew up in the age of neuroscience when neural networks were discussed, computational neuroscience and theoretical neuroscience, they had their own journals. It wasn't actually taken terribly seriously by experimentalists until a few years ago. I would say about five to seven years ago, excellent theoretical neuroscientists like Larry Abbott and other, I've colleagues certainly at Stanford as well, that people started paying attention to computational methods. But these terms, neural networks, computational methods, I actually didn't know that neural networks and deep learning were, those have now become kind of synonymous.

• 23:09Lex Fridman?

  No, they were always, no, they're always the same thing.

• 23:12Andrew D. Huberman?

  Interesting.

• 23:13Lex Fridman?

  It was, so.

• 23:14Andrew D. Huberman?

  I'm a neuroscientist and I didn't know that.

• 23:15Lex Fridman?

  So, well, because neural networks probably mean something else in neuroscience, not something else, but a little different flavor, depending on the field. And that's fascinating too, because neuroscience and AI, people have started working together and dancing a lot more in the recent, I would say, probably decade.

• 23:33Andrew D. Huberman?

  Machines are going into the brain. I have a couple of questions, but one thing that I'm sort of fixated on that I find incredibly interesting is this example you gave of playing a game with a mutated version of yourself as a competitor.

• 23:49Lex Fridman?

  Yeah.

• 23:50Andrew D. Huberman?

  I find that incredibly interesting as a kind of a parallel or a mirror for what happens when we try and learn as humans, which is we generate repetitions of whatever it is we're trying to learn and we make errors. Occasionally, we succeed. In a simple example, for instance, of trying to throw bullseyes on a dartboard.

• 24:08Lex Fridman?

  Yeah.

• 24:09Andrew D. Huberman?

  I'm gonna have errors, errors, errors. I'll probably miss the dartboard and maybe occasionally hit a bullseye. And I don't know exactly what I just did, right? But then, let's say I was playing darts against a version of myself where I was wearing a visual prism, like my visual, I had a visual defect.

• 24:26Andrew D. Huberman?

  You learn certain things in that mode as well. You're saying that a machine can sort of mutate itself. Does the mutation always cause a deficiency that it needs to overcome? Because mutations in biology sometimes give us superpowers, right? Occasionally, you'll get somebody who has better than 2020 vision and they can see better than 99.9% of people out there.

• 24:46Lex Fridman?

  Mm-hmm.

• 24:46Andrew D. Huberman?

  So when you talk about a machine playing a game against a mutated version of itself, is the mutation always what we call a negative mutation or an adaptive or a maladaptive mutation?

• 24:57Lex Fridman?

  No, you don't know until you get, so you mutate first and then figure out and they compete against each other.

• 25:04Andrew D. Huberman?

  So you're evolving, the machine gets to evolve itself in real time?

• 25:08Lex Fridman?

  Yeah. And I think of it, which would be exciting if you could actually do with humans. It's not just, so usually you freeze a version of the system. So really, you take an Andrew of yesterday and you make 10 clones of them. And then maybe you mutate, maybe not. And then you do a bunch of competitions of the Andrew of today, like you fight to the death. Who wins last? So I love that idea of like creating a bunch of clones of myself from like, from each of the day for the past year and just seeing who's going to be better at like podcasting or science or picking up chicks at a bar or, I don't

• 25:50Lex Fridman?

  know, or competing in jiu-jitsu. That's the one way to do it. I mean, a lot of Lexes would have to die for that process. But that's essentially what happens is in reinforcement learning through the self-play mechanisms, it's a graveyard of systems that didn't do that well. And the surviving, the good ones survive.

• 26:09Andrew D. Huberman?

  Do you think that Darwin's theory of evolution might have worked in some sense in this way, but at the population level? I mean, you get a bunch of birds with different shaped beaks and some birds have the shaped beak that allows them to get the seeds. I mean, it's a trivial, trivially simple example of Darwinian evolution, but I think it's correct, if not, even though it's not exhaustive. Is that what you're referring to? You essentially that normally this is done between members of a different species, lots of different members of species have different traits and some get selected for, but you could actually create multiple versions of yourself with different traits?

• 26:43Lex Fridman?

  So with, I should probably have said this, but perhaps it's implied, but machine learning with reinforcement learning through these processes, one of the big requirements is to have an objective function, a loss function, a utility function, those are all different terms for the same thing, is there's like an equation that says what's good and then you're trying to optimize that equation. So there's a clear goal for these systems.

• 27:10Andrew D. Huberman?

  Because it's a game, like with chess, there's a goal.

• 27:13Lex Fridman?

  But for anything, anything you want machine learning to solve, there needs to be an objective function. In machine learning, it's usually called loss function that you're optimizing. The interesting thing about evolution, complicated of course, but the goal also seems to be evolving, like it's, I guess, adaptation to the environment is the goal, but it's unclear you can convert that always. It's like survival of the fittest. It's unclear what the fittest is. In machine learning, the starting point, and this is like what human ingenuity provides, is that fitness function of what's good and what's bad, which it lets you know which of the systems is going to win.

• 27:58Lex Fridman?

  So you need to have an equation like that. One of the fascinating things about humans is we figure out objective functions for ourselves, like we're, it's the meaning of life, like why the hell are we here? And a machine currently has to have a hardcoded statement about why.

• 28:19Andrew D. Huberman?

  It has to have a meaning of artificial intelligence based life.

• 28:23Lex Fridman?

  Right. It can't, so like there's a lot of interesting explorations about.

• 28:29Lex Fridman?

  That function being more about curiosity, about learning new things and all that kind of stuff, but it's still hardcoded. If you want a machine to be able to be good at stuff, it has to be given very clear statements of what good at stuff means. That's one of the challenges of artificial intelligence is you have to formalize the, in order to solve a problem, you have to formalize it and you have to provide both like the full sensory information, you have to be very clear about what is the data that's being collected, and you have to also be clear about the objective function. What is the goal that you're trying to reach? And that's a very difficult thing for artificial intelligence.

• 29:11Andrew D. Huberman?

  I love that you mentioned curiosity. I, I'm sure this definition falls short in many ways, but I define curiosity as a, a strong interest in knowing something, but without an attachment to the outcome. You know, it's sort of a, uh, it's not, it could be a random search, but it, there's not really an emotional attachment. It's really just a desire to discover and unveil what's there without hoping it's a, you know, a gold coin under a rock, you're just looking under rocks. Is that more or less how the machine, you know, within machine learning, it sounds like there are elements of reward prediction and, you know, rewards, the machine has to know when it's done the right thing.

• 29:51Andrew D. Huberman?

  So it, can you make machines that are curious or are the sorts of machines that you are describing curious by design?

• 29:59Lex Fridman?

  Yeah, curiosity is a kind of symptom, not the goal. So what, what happens is, uh, one of the big trade-offs in reinforcement learning is this exploration versus exploitation. So when you know very little, it pays off to explore a lot, even suboptimal, like even trajectories that seem like they're not going to lead anywhere. That's called exploration. The smarter and smarter and smarter you get, the, the more emphasis you put on exploitation, meaning you take the best solution, you take the best path. Now through that process, the exploration.

• 30:39Lex Fridman?

  Can look like curiosity by us humans, but it's really just trying to get out of the local optimal of the thing that's already discovered. It's it's from an AI perspective, it's always looking to optimize the objective function. It derives, and we could talk about this a lot more, but in terms of the tools of machine learning today, it derives no pleasure from just the curiosity of like, I don't know, discovery.

• 31:09Andrew D. Huberman?

  So there's no dopamine for

• 31:10Lex Fridman?

  There's no dopamine.

• 31:11Andrew D. Huberman?

  There's no reward system, chemical, or I guess electronic reward system.

• 31:16Lex Fridman?

  That said, if you look at machine learning literature and reinforcement learning literature, they will use like DeepMind will use terms like dopamine. We're constantly trying to use the human brain to inspire totally new solutions to these problems. So they'll think like, how does dopamine function in the human brain? And how can that lead to more interesting ways to discover optimal solutions? But ultimately, currently, the there has to be a formal objective function. Now, you could argue that humans also has a set of objective functions we're trying to optimize, we're just not able to introspect them.

• 31:53Andrew D. Huberman?

  We yeah, we don't actually know what we're looking for and seeking and doing.

• 31:59Lex Fridman?

  Well, like Lisa Feldman Barrett, you've spoken with at least on Instagram.

• 32:02Andrew D. Huberman?

  I met her through you.

• 32:04Lex Fridman?

  Yeah, I hope you actually have her on this podcast.

• 32:07Andrew D. Huberman?

  She's terrific.

• 32:08Lex Fridman?

  So she has a very, it has to do with homeostasis like that. Basically, there's a very dumb objective function that the brain is trying to optimize, like to keep like body temperature the same. Like, there's a very dumb kind of optimization function happening. And then what we humans do with our fancy consciousness and cognitive abilities is we tell stories to ourselves so we can have nice podcasts. But really, it's the brain trying to maintain just like healthy state, I guess. That's fascinating. I also.

• 32:44Lex Fridman?

  See the human brain and I hope artificial intelligence systems as not just systems that solve problems or optimize a goal, but also storytellers. I think there's a power to telling stories. We tell stories to each other. That's what communication is. Like when you're alone, that's when you solve problems. That's when it makes sense to talk about solving problems. But when you're a community, the capability to communicate, tell stories, whole, share ideas in such a way that those ideas are stable over a long period of time. That's like, that's being a charismatic storyteller. And I think both humans are very good at this.

• 33:25Lex Fridman?

  Arguably, I would, I would argue that's why we are who we are is we're great storytellers. And then AI, I hope will also become that. So it's not just about being able to solve problems with a clear objective function. It's afterwards be able to tell like a way better, like make up a way better story about why you did something or why you failed.

• 33:45Andrew D. Huberman?

  So you think that robots and or machines of some sort are going to start telling humans stories?

• 33:52Lex Fridman?

  Well, definitely. So the technical field for that is called explainable AI. Explainable artificial intelligence is trying to figure out how you get the AI system to explain to us humans why the hell it failed or why it succeeded. Or there's a lot of different sort of versions of this or to visualize how it understands the world. That's a really difficult problem, especially with neural networks that are famously opaque. That they, we don't understand in many cases why a particular neural network does what it does so well. And to try to figure out where it's going to fail, that requires the AI to explain itself.

• 34:36Lex Fridman?

  There's a huge amount of money, like there's a huge amount of money in this, especially from government funding and so on. Because if you want to deploy.

• 34:47Lex Fridman?

  AI systems in the real world, we humans at least, want to ask it a question like, why the hell did you do that? Like, in a dark way, why did you just kill that person? Right? Like, if a car ran over a person, we want to understand why that happened. And now, again, we're sometimes very unfair to AI systems because we humans can often not explain why very well. But that's the field of explainable AI. That's very, people are very interested in because the more and more we rely on AI systems, like the Twitter recommender system, that AI algorithm, that's, I would say, impacting elections, perhaps starting wars, or at least military conflict, that's, that

• 35:32Lex Fridman?

  algorithm, we want to ask that algorithm, first of all, do you know what the hell you're doing? Do you know, do you understand the society level effects you're having? And can you explain the possible other trajectories? Like, we would have that kind of conversation with a human, we want to be able to do that with an AI. And at my own personal level, I think it would be nice to talk to AI systems for stupid stuff, like robots, when they fail, to- Why'd you fall down the stairs? Yeah, but I'm not an engineering question, but almost like an endearing question. Like, like, I'm looking for, if I fell and you and I were hanging out, I don't think

• 36:15Lex Fridman?

  you need an explanation exactly what were the dynamic, like, what was the under-actuated system problem here? Like, what was the texture of the floor, or so on, or, like, what was the- I want to know what you're thinking. That, or you might joke about, like, you're drunk again, go home, or something, like, there could be humor in it. That, that's an opportunity, like, storytelling isn't just explanation of what happened. It's something that makes people laugh, makes people fall in love, makes people dream, and understand things in a way that poetry makes people understand things, as opposed to a rigorous log of where every sensor was, where every actuator was.

• 36:59Andrew D. Huberman?

  I mean, I find this incredible because, you know, one of the hallmarks of severe autism spectrum disorders is a report of experience from the autistic person that is very much a catalog of of action steps. It's like, how do you feel today? And they'll say, well, I got up and I did this, and then I did this, and I did this. And it's not at all the way that a a person with who doesn't have autism spectrum disorder would would respond. And the way you describe these machines has so much human has so much humanism or so much of of a human and biological element. But I realize that we are talking about machines.

• 37:38Andrew D. Huberman?

  I I want to make sure that I understand if there's a distinction between a machine that learns, a machine with artificial intelligence, and a robot. At what point does a machine become a robot? So if I have a ballpoint pen, I'm assuming I wouldn't call that a robot. But if my ballpoint pen can come to me when it's on when I move to the opposite side of the table, if it moves by whatever mechanism, at that point, does it become a robot?

• 38:10Lex Fridman?

  Okay, there's a million ways to explore this question. It's a fascinating one. So first of all, there's a question of what is life? Like, how do you know something is a living form or not? And it's similar to the question of when does sort of a maybe a cold computational system becomes a we're already loading these words with a lot of meaning, robot and machine. But so one, I think movement is is important. But but that's a kind of a boring idea that a robot is just a machine that's able to act in the world. So one, artificial intelligence could be

• 38:50Lex Fridman?

  Both just the thinking thing, which I think is what machine learning is, and also the acting thing, which is what we usually think about robots. So robots are the things that have a perception system that's able to take in the world, however you define the world, is able to think and learn and do whatever the hell it does inside, and then act on the world. So that's the difference between maybe an AI system or a machine and a robot. It's something that's able, a robot is something that's able to perceive the world and act in the world.

• 39:18Andrew D. Huberman?

  So it could be through language or sound, or it could be through movement or both?

• 39:22Lex Fridman?

  Yeah, and I think it could also be in the digital space, as long as there's a aspect of entity that's inside the machine and a world that's outside the machine, and there's a sense in which the machine is sensing that world and acting in it.

• 39:39Andrew D. Huberman?

  So it could, for instance, there could be a version of a robot, according to your, the definition that I think you're providing, where the robot, I, where I go to sleep at night and this robot goes and forages for information that it thinks I want to see, load it onto my desktop in the morning. There was no movement of that machine, there was no language, but it essentially has movement in cy- in cyberspace.

• 40:01Lex Fridman?

  Yeah, there's a distinction that I think is important in that there's a, there's an element of it being an entity, whether it's in the digital or the physical space. So when you have something like Alexa in your home, most of the speech recognition, most of what Alexa's doing is constantly being sent back to the mothership. The, when Alexa is there on its own, that's to me a robot. When it's there interacting with the world. When it's simply a finger of the main mothership, that's not, then Alexa's not a robot.

• 40:46Lex Fridman?

  Then it's just an interaction device. That then maybe the main Amazon Alexa AI, big, big system is the robot. So the, that's important because there's some element to us humans, I think, where we want there to be an entity, whether in the digital or the physical space. That's where ideas of consciousness come in and all those kinds of things that we project our understanding what it means to be a being.

• 41:14Lex Fridman?

  And so to take that further, when does a machine become a robot?

• 41:21Lex Fridman?

  I think there's a, there's a special moment. There's a special moment in a person's life, in a robot's life, where it surprises you. I think surprise is a really powerful thing, where you know how the thing works and yet it surprises you. That, that's a magical moment for us humans. So whether it's a chess playing program that does something that you haven't seen before, that makes people smile, like huh. Those moments happened with Alpha Zero for the first time in chess playing, where grandmasters were really surprised by a move. They didn't understand the move and then they studied and studied and then they understood it.

• 42:03Lex Fridman?

  But that moment of surprise, that's for grandmasters in chess. I find that moment of surprise really powerful, really magical in just everyday life. Because it supersedes the, the human brain in that moment? Not, uh, so it's not supersedes like outperforms, but uh, surprises you in a positive sense. Like I didn't, I didn't think you could do that. I, I didn't think that you had that in you. And I think that moment is a big transition for a robot from a, from a moment of being a servant that partic, that accomplishes a particular task with some level of accuracy, with some rate of, of failure,

• 42:45Lex Fridman?

  to an entity, a being that's struggling just like you are in this world. And that, that's a really important moment that I think, uh, you're not going to find many people in the AI community that talk like I just did.

• 43:01Lex Fridman?

  I, I'm not speaking like some philosopher or some hippie. I'm speaking from purely engineering perspective. I think it's really important for robots to become entities and explore that as a real engineering problem. As opposed to, uh, everybody treats robots in the robotic community. They don't even call them a he or she, they don't give them, try to avoid giving them names. They really want to see it like a system, uh, like a, a servant. They see it as a servant that's trying to accomplish a task. To me, And I don't think I'm just romanticizing the notion. I think it's a being. It's currently perhaps a dumb being, but in the, in the long arc of uh history, humans are pretty dumb beings too, so.

• 43:45Andrew D. Huberman?

  I, I would agree with that statement.

• 43:47Lex Fridman?

  So I, I tend to really want to explore this, uh, treating robots really as uh, as entities. Um, yeah, so like anthropomorphization, which is the, sort of the act of looking at a inanimate object and projecting onto it lifelike features. I think robotics generally sees that um, as a, as a negative. I see it as a superpower. Like that, we need to use that.

• 44:16Andrew D. Huberman?

  Well, I'm struck by how that really grabs on to the relationship between human and machine, or human and robot. So it's the simple question is, and I think you've already told us the answer, but does interacting with a robot change you? Does it, in other words, do, do we develop relationships to robots?

• 44:38Lex Fridman?

  Yeah, I think, I definitely, I definitely think so. I think uh, I think the moment you see a robot or AI systems as more than just servants, but uh, entities, they begin to change you, just like good friends do, just like um, relationships, just like other humans. I think for that, you have to have certain aspects of that interaction, like the robot's ability to um, say no, to uh, to have its own sense of identity, to have its own set of goals, that's not constantly serving you, but instead trying to understand the world and uh, do that dance of understanding through communication with you. So I, I definitely

• 45:19Lex Fridman?

  think there's a, I mean, I have a lot of thoughts about this, as you may know, uh, and that's at the core of my lifelong dream, actually, of what I want to do, which is um, I believe that most people have.

• 45:36Lex Fridman?

  A notion of loneliness in them that we haven't discovered, that we haven't explored, I should say. And I see AI systems as helping us explore that so that we can become better humans, better people towards each other. So I think that connection between human and AI, human and robot is not only possible, but will help us understand ourselves in ways that are like several orders of magnitude, deeper than we ever could have imagined. I

• 46:11Lex Fridman?

  tend to believe that, well, I have a very wild levels of belief in terms of how impactful that would be.

• 46:25Andrew D. Huberman?

  So when I think about human relationships, I don't always break them down into variables, but we could explore a few of those variables and see how they map to human-robot relationships. One is just time, right? If you spend zero time with another person at all in cyberspace or on the phone or in person, you essentially have no relationship to them. If you spend a lot of time, you have a relationship. This is obvious, but I guess one variable would be time. How much time you spend with the other entity, robot or human. The other would be wins and successes. You know, you enjoy successes together. I'll give an absolutely trivial example of this in a moment, but the other would be failures. When you struggle

• 47:09Andrew D. Huberman?

  with somebody, whether or not you struggle between one another, you disagree. Like, I was really struck by the fact that you said that robots saying no, I've never thought about a robot saying no to me. But there it is.

• 47:21Lex Fridman?

  I look forward to you being one of the first to put this robot to.

• 47:25Andrew D. Huberman?

  So do I. So there's there's struggle. You grow, you know, when you struggle with somebody, you grow closer. Sometimes the struggles are imposed between those two people, so-called trauma bonding. They call it in the whole psychology literature and pop psychology literature. But in any case, I could imagine so time, successes together, struggle together, and then just peaceful time, hanging out at home, watching, watching movies, waking up near one another. Here we're breaking down the elements of relationships of any kind. So do you think that these elements?

• 48:03Andrew D. Huberman?

  Apply to robot-human relationships. And if so, then I could see how if the if the robot is its own entity and has some autonomy in terms of how it reacts to you, it's not just there just to serve you. It's not just a servant. It actually has opinions and can tell you when maybe your thinking is flawed or your actions are flawed.

• 48:25Lex Fridman?

  It can also leave.

• 48:27Andrew D. Huberman?

  It can could also leave. So I've never conceptualized robot-human interactions this way. So tell me more about how this might look. Are we thinking about a human appearing robot? I know you and I have both had intense relationships to our we have separate dogs, obviously, but to animals. This sounds a lot like human-animal interaction. So what is the ideal human-robot relationship?

• 48:54Lex Fridman?

  So there's a lot to be said here, but you actually pinpointed one of the big, big first steps, which is this idea of time. And it's a huge limitation in machine learning community currently. As now we're back to like the actual details. Lifelong learning is a is a is a problem space that focuses on how AI systems can learn over a long period of time. What's currently most machine learning systems are not able to do is to all of the things you've listed under time, the successes, the failures, are just chilling together, watching movies.

• 49:34Lex Fridman?

  AI systems are not able to do that, which is all the beautiful, magical moments that I believe are the days filled with. They're not able to keep track of those together with you.

• 49:47Andrew D. Huberman?

  Because they can't move with you and be with you.

• 49:49Lex Fridman?

  No, no, like literally, we don't have the techniques to do the learning, the actual learning of containing those moments. Current machine learning systems are really focused on understanding the world in the following way. It's more like the perception system, like looking around, understand.

• 50:07Lex Fridman?

  Uh, like what's in the scene? That there's a bunch of people sitting down, that there is uh cameras and microphones, that there's a table, understand that. But the fact that we shared this moment of talking today and still remember that for next time you're for like uh, next time you're doing something, remember that this moment happened. We don't know how to do that technique wise. This is what I'm, this is what I'm hoping to innovate on. As I think it's a very, very important component of what it means to create a deep relationship, that sharing of moments together.

• 50:42Andrew D. Huberman?

  Could you post a photo of you and the robot, like selfie with robot? And then the robot sees that image and recognizes that was time spent, there was, there were smiles or there were tears.

• 50:53Lex Fridman?

  Yeah.

• 50:53Andrew D. Huberman?

  And create some sort of um metric of, of emotional depth in the relationship and update its behavior?

• 51:01Lex Fridman?

  So.

• 51:03Andrew D. Huberman?

  Could it text you in the middle of the night and say, why haven't you texted me back?

• 51:06Lex Fridman?

  Well, yes, all of those things. But we could, we could dig into that. But I think that time element, forget everything else, just sharing moments together, that changes everything. I believe that changes everything. Uh, there's specific things that are more in terms of systems that can explain you.

• 51:27Lex Fridman?

  It's, it's more technical and probably a little bit offline because I have kind of wild ideas how that can revolutionize um social networks and um, and operating systems. But the point is that element alone. Forget all the other things we're talking about, like emotions, saying no, all that, just remember sharing moments together would change everything. We don't currently have systems that uh, um, share, share moments together, like even just you and your fridge. Just all those times you went late at night and ate the thing you shouldn't have eaten. That was a secret moment you had with your refrigerator. You shared that moment, that darkness or that beautiful moment

• 52:10Lex Fridman?

  where you just uh, you know, like heartbroken for some reason, you're eating that ice cream or whatever. That's a special moment and that refrigerator was there for you. And the fact that it missed the opportunity to remember that uh, is, is tragic. And once it does remember that. I think you're gonna be very attached to their refrigerator. You're gonna go through some through some hell with that refrigerator. Most of us have like in a in a developed world have weird relationships with food, right? So you can go through some some deep moments of trauma and triumph with food. And at the core of that is the refrigerator. So a smart refrigerator, I believe, would change society.

• 52:54Lex Fridman?

  Not just the refrigerator, but the these ideas in the systems all around us. So that I just want to comment on how powerful that idea of time is. And then there's a bunch of elements of actual interaction of

• 53:11Lex Fridman?

  allowing you as a human to feel like you're being heard. Truly heard, truly understood. That we human like deep friendship is like that, I think. But we're still, there's still an element of selfishness. There's still an element of not really being able to understand another human. And a lot of the times when you're going through trauma together, through difficult times and through successes, you're actually starting to get that inkling of understanding of each other. But I think that could be done more aggressively, more efficiently. Like if you think of a great therapist, I think I've never actually been to a therapist, but I'm a believer, I used to want to be a psychiatrist.

• 53:55Andrew D. Huberman?

  Do Russians go to therapists?

• 53:56Lex Fridman?

  No, they don't, they don't. And if they do, the therapist don't live to tell the story, no. I I do believe in talk therapy, which friendship is to me is is talk therapy. Or like it's like it's you don't necessarily need to talk. It's like just connecting through in the space of ideas and the space of experiences. And I think there's a lot of ideas of how to make AI systems to be able to ask the right questions and truly hear another human. This is what we try to do with podcasting, right? I think there's ways to do that with AI. But above all else, just remembering the collection of moments that make up the day, the week, the months.

• 54:42Lex Fridman?

  I think you maybe have some of this as well. Some of my closest friends still are the friends from high school. That's time. We've been through a bunch of shit together. And that, like, we've, we're very different people. But just the fact that we've been through that and we remember those moments and those moments somehow create a depth of connection like nothing else. Like you and your refrigerator.

• 55:06Andrew D. Huberman?

  I, I love that because the, I had a, my graduate advisor, unfortunately, she passed away. But when she passed away, somebody said at her, um, at her memorial,

• 55:17Andrew D. Huberman?

  you know, all these amazing things she had done, et cetera. And then her kids got up there and she had young children that I knew as they were, when she was pregnant with them. And so it was really, you know, even now I can feel like your heart gets heavy thinking about this. They're going to grow up without their mother. And it was really amazing, very, very strong, uh, young girls and now young women. And what they said was incredible. They said what they really appreciated most about their mother, who was an amazing person, is all the unstructured time they spent together. So it wasn't the trips to the zoo. It wasn't, you know, oh, you know, she woke up at five in the morning and drove us to school. She did all those things too. She had two hour commute in each direction. It was incredible, ran a lab, et cetera. But it was the unstructured time.

• 56:01Andrew D. Huberman?

  So on the passing of their mother, that, that's what they remembered was the, the biggest give. And what bonded them to her was all the time where they just kind of hung out. And the way you described the relationship to a refrigerator is so, I want to say human-like, but I'm almost reluctant to say that because what I'm realizing as we're talking is that what we think of as human-like might actually be the, a lower form of relationship. There may be relationships that are far better than the sorts of relationships that we can conceive in our minds right now, based on what these machine relationship interactions could teach us. Do I have that right?

• 56:42Lex Fridman?

  Yeah, I think so. I think there's no reason to see machines as somehow incapable of teaching us something that's deeply human. I, I don't think, uh, humans have a monopoly on that. I think we understand ourselves very poorly and we need to have the kind of, uh, prompting from, uh, from a machine. And definitely part of that is just remembering the moments, remembering the moments. I'm, I'm, you know, I think the unstructured time together.

• 57:14Lex Fridman?

  I wonder if it's quite so unstructured. That's like calling this podcast unstructured time.

• 57:20Andrew D. Huberman?

  Maybe what they meant was it wasn't a big outing. It wasn't a, there was no specific goal, but a goal was created through the lack of a goal. Like where you just hang out and then you start playing, you know, thumb war. You end up playing thumb war for an hour there. So it's, it's the structure emerges from lack of structure.

• 57:38Lex Fridman?

  No, but the thing is the moments, there's something about those times that creates special moments. And I think that those could be optimized for. I think we think of like a big outing is, I don't know, going to Six Flags or something, or some big, the Grand Canyon, or go into some, I don't know. I think we would need to, we don't quite yet understand as humans what creates magical moments. I think there's possible to optimize a lot of those things. And perhaps like podcasting is helping people discover that like, uh, maybe the thing we want to optimize for isn't necessarily, uh, like some sexy, uh, like quick clips.

• 58:21Lex Fridman?

  Maybe what we want is long form authenticity.

• 58:24Andrew D. Huberman?

  Depth.

• 58:25Lex Fridman?

  Depth. So we were trying to figure that out, uh, certainly from a deep connection between, between humans and humans and AI systems. I think long conversations or long periods of communication over a series of moments, like minute, perhaps seemingly insignificant to the big ones, the big successes, the big, uh, failures. Those are all just stitching those together and talking throughout. I think that's the formula for a really, really deep connection that from a, like a very specific engineering perspective, is, um, I think a fascinating, open problem that hasn't been really worked on very much.

• 59:08Lex Fridman?

  And for me, from a, if I have the guts and, um, I mean, there's a lot of things to say, but one of it is guts. Uh, is I'll build a startup around it.

• 59:19Andrew D. Huberman?

  Yeah. So let's talk about this startup and let's talk about the, the dream. You've mentioned this dream before in our previous conversations, always as little hints dropped here and there, just for anyone listening, there's never been an offline conversation about this dream. I'm not privy to anything, except what Lex says now. And I realize that there's no way to capture the full essence of a dream in any kind of verbal statement in a way that captures all of it. But what is the, what is this dream that you've referred to now several times, when we've sat down together and talked on the phone? Maybe it's this company, maybe it's something distinct. If you feel comfortable, it'd be great if you could share a little bit about what that is.

• 1:00:03Lex Fridman?

  Sure. So the, the way people express long-term vision, I've noticed is quite different. Like Elon is an example of somebody who can very crisply say exactly what the goal is. Also has to do with the fact the problems he's solving have nothing to do with humans. So my long-term vision is a little bit more difficult to express in words. I've noticed as I've tried. It could be my brain's failure. But there's ways to sneak up to it. So let me just say a few things. Early on in life, in, also in the recent years, I've interacted

• 1:00:43Lex Fridman?

  with a few robots where I understood there's magic there. And that magic could be shared by millions, if it's brought to light. When I first met Spot from Boston Dynamics, I realized there's magic there that nobody else is seeing.

• 1:01:00Andrew D. Huberman?

  Is the dog.

  Is it the dog, sorry. The Spot is the four-legged robot from Boston Dynamics. Some people might have seen it. It's this yellow dog. And, you know, sometimes in, in life, you just notice something that just grabs you. And I believe that this is something that, this magic is something that could be every single device in the world.

• 1:01:28Lex Fridman?

  The way that I think maybe Steve Jobs thought about the personal computer. Was didn't think about the personal computer this way, but Steve did. Which is like, he thought that the personal computer should be as thin as a sheet of paper and everybody should have one. I mean, this idea, I think it is heartbreaking that we're getting, the world is being filled up with machines that are soulless. And I think every one of them can have that same magic. One of the things that also inspired me in terms of a startup is that magic can be engineered much easier than I thought. That's my intuition with everything I've ever built and worked on.

• 1:02:13Lex Fridman?

  So the dream is to add a bit of that magic in every single computing system in the world. So the way that Windows operating system for a long time was the primary operating system everybody interacted with. They built apps on top of it. I think this is something that should be as a layer, almost as an operating system in every device that humans interact with in the world. Now, what that actually looks like, the actual dream when I was especially a kid, it didn't have this concrete form of a business. It had more of a dream of exploring your own loneliness

• 1:02:58Lex Fridman?

  by interacting with machines, robots. This deep connection between humans and robots was always a dream. And so for me, I'd love to see a world where there's every home has a robot. And not a robot that washes the dishes or a sex robot. Or, I don't know, I think of any kind of activity the robot can do, but more like a companion. A family member. A family member, the way a dog is. But a dog that's able to speak your language too. So not just connect the way a dog does by looking at you and looking away and almost like smiling with its soul in that kind of way.

• 1:03:41Lex Fridman?

  But also to actually understand what the hell, like, why are you so excited about the successes? Like, understand the details, understand the traumas. And I just think. That had always filled me with excitement that I could with artificial intelligence bring joy to a lot of people. More recently, I've been more and more heartbroken to see the kind of division, derision, even hate that's boiling up on the internet through social networks. And I thought this kind of mechanism is exactly applicable in the context of social networks as well.

• 1:04:24Lex Fridman?

  So it's an operating system that serves as your guide to, on the internet. One of the biggest problems with YouTube and social networks currently is they're optimizing for engagement. I think if you create AI systems that know each individual person, you're able to optimize for long-term growth, for a long-term happiness.

• 1:04:50Andrew D. Huberman?

  Of the individual?

• 1:04:51Lex Fridman?

  Of the individual, of the individual. And there's a lot of other things to say, which is the, in order for AI systems to learn everything about you, they need to collect, they need to, just like you and I, when we talk offline, we're collecting data about each other, secrets about each other. The same way AI has to do that. And that allows you to, and that requires you to rethink ideas of ownership of data. I think each individual should own all of their data and very easily be able to leave, just like AI systems can leave,

• 1:05:33Lex Fridman?

  humans can disappear and delete all of their data in a moment's notice, which is actually better than we humans can do. Because once we load the data into each other, it's there. I think it's very important to be both, give people complete control over their data in order to establish trust that they can trust you. And the second part of trust is transparency. Whenever the data is used, to make it very clear what it's being used for. And not clear in a lawyerly legal sense, but clear in a way that people really understand what it's used for. I believe when people have the ability to delete all their data and walk away and know how the data is being used, I think they'll stay.

• 1:06:19Andrew D. Huberman?

  The possibility of a clean breakup is actually what will keep people together.

• 1:06:23Lex Fridman?

  Yeah, I think so. I think, exactly. I think a happy marriage requires the ability to divorce easily without the divorce industrial complex or whatever is currently going on. There's so much money to be made from lawyers and divorce. But yeah, the ability to leave is what enables love, I think.

• 1:06:45Andrew D. Huberman?

  It's interesting. I've heard the phrase from a semi cynical friend that marriage is the leading cause of divorce. But now we've heard that divorce or the possibility of divorce could be the leading cause of marriage.

• 1:06:56Lex Fridman?

  Of a happy marriage.

• 1:06:58Andrew D. Huberman?

  Good point.

• 1:06:58Lex Fridman?

  Of a happy marriage. So yeah, but there's a lot of details there. But the big dream is that connection between AI system and a human. And I haven't, you know, there's so much fear about artificial intelligence systems and about robots that I haven't quite found the right words to express that vision because the vision I have is one, it's not like some naive, delusional vision of like, technology is going to save everybody. It's, I really do just have a positive view of ways AI systems can help humans explore themselves.

• 1:07:34Andrew D. Huberman?

  I love that positivity and I agree that the stance, everything is doomed, is equally bad to say that everything's going to turn out all right. There has to be a dedicated effort. And clearly, you're thinking about what that dedicated effort would look like. You mentioned two, two aspects to this dream. And I want to make sure that I understand where they connect, if they do, or if these are independent streams. One was this hypothetical robot family member or some other form of robot that would allow people to experience the kind of delight that you experienced many times and that you would like the world to.

• 1:08:19Andrew D. Huberman?

  To be able to have, and it's such a beautiful idea of this give. And the other is social media or social network platforms that really serve individuals and their best selves and their happiness and their growth. Is there crossover between those or are these two parallel dreams?

• 1:08:37Lex Fridman?

  It's 100% the same thing. It's difficult to kind of explain without going into details, but maybe one easy way to explain the way I think about social networks is to create an AI system that's yours. That's yours. It's not like Amazon Alexa that's centralized. You own the data. It's like your little friend that becomes your representative on Twitter. That helps you find things that will make you feel good, that will also challenge your thinking to make you grow, but not get to that, not let you get lost in the negative

• 1:09:15Lex Fridman?

  spiral of dopamine that gets you to be angry or most just gets you to be not open to learning. And so that little representative is optimizing your long-term health. And it's, I believe that that is not only good for human beings, it's also good for business. I think long-term you can make a lot of money by challenging this idea that the only way to make money is maximizing engagement. And one of the things that people disagree with me on is they think Twitter is always going to win, like maximizing engagement is always going to win. I don't think so.

• 1:09:56Lex Fridman?

  I think people have woken up now to understanding that like they don't always feel good, the ones who are on Twitter a lot, that they don't always feel good at the end of the week.

• 1:10:09Andrew D. Huberman?

  I would love feedback from whatever this creature, whatever, I can't, I don't know what to call it, as to, you know, maybe at the end of the week, it would automatically unfollow some of the people that I follow because it realized through some really smart data about how I was feeling inside or how I was sleeping or something that, you know, that just wasn't good for me. But it might also put things and people in front of me that I ought to see. Is that kind of sliver of what this, what this looks like?

• 1:10:38Lex Fridman?

  The whole point, because of the interaction, because of sharing the moments and learning a lot about you.

• 1:10:46Lex Fridman?

  You're now able to understand what interactions led you to become a better version of yourself, like the person you yourself are happy with. This isn't, you know, if you're into a flat earth and you feel very good about it, that you believe the earth is flat. Like the idea that you should censor that is ridiculous. If it makes you feel good and you're becoming the best version of yourself, I think you should be getting as much flat earth as possible. Now, it's also good to challenge your ideas, but not because the centralized committee decided, but because you tell to the system that you like challenging your ideas. I think all of us do.

• 1:11:30Lex Fridman?

  And then, which actually YouTube doesn't do that well. Once you go down the flat earth rabbit hole, that's all you're gonna see. It's nice to get some really powerful communicators to argue against flat earth. And it's nice to see that for you and potentially, at least long term, to expand your horizons. Maybe the earth is not flat. But if you continue to live your whole life thinking the earth is flat, I think, and you're being a good father or son or daughter and like you're being the best version of yourself and you're happy with yourself, I think the earth is flat. So like I, I, I think this kind of idea, and I'm just using that kind of silly ridiculous example,

• 1:12:14Lex Fridman?

  because I don't like the idea of centralized forces controlling what you can and can't see. But I also don't like this idea of like not censoring anything. Because that's always the biggest problem with that is this, it's the, there's a central decider. I think you yourself can decide what you want to see and not. And it's good to have a companion that reminds you that you felt shitty last time you did this or you felt good last time you did this.

• 1:12:48Andrew D. Huberman?

  I mean, I feel like in every good story, there's a, there's a guide or a companion that flies out or forages a little bit further or a little bit differently and brings back information that helps us, or at least tries to steer us in the right direction.

• 1:13:01Lex Fridman?

  So actually, that's exactly, that's exactly the.

• 1:13:05Lex Fridman?

  What I'm thinking and what I've been working on, I should mention there's a bunch of difficulties here. You see me up and down a little bit recently. So there's technically a lot of challenges here. Like with a lot of technologies and the reason I'm talking about it on a podcast comfortably as opposed to working in secret is it's really hard. And maybe it's time has not come.

• 1:13:32Lex Fridman?

  And that's something you have to constantly struggle with in terms of like entrepreneurially as a startup.

• 1:13:38Lex Fridman?

  Like I've also mentioned to you, maybe offline, I really don't care about money. I don't care about business success, all those kinds of things.

• 1:13:48Lex Fridman?

  So it's a difficult decision to make. How much of your time? Do you want to go all in here and give everything to this? It's a big roll of the dice. Because I've also realized that working on some of these problems, both with the robotics and the technical side in terms of the machine learning system that I'm describing.

• 1:14:13Lex Fridman?

  It's lonely.

• 1:14:15Lex Fridman?

  It's really lonely. Because both on a personal level and a technical level. So on the technical level, I'm surrounded by people that kind of

• 1:14:26Lex Fridman?

  doubt me, which I think all entrepreneurs go through. And they doubt you in the following sense. They

• 1:14:35Lex Fridman?

  they know how difficult it is, like the people that the colleagues of mine, they know how difficult lifelong learning is. They also know how difficult it is to build a system like this, to build a competitive social network. And

• 1:14:51Lex Fridman?

  in general, there's a kind of loneliness to

• 1:14:56Lex Fridman?

  Just working on something on your own for a long periods of time and you start to doubt whether, given that you don't have a track record of success, like that's a big one. When you look in the mirror, especially when you're young, but I still have that on most things. You look in the mirror, it's like, and you have these big dreams. How do you know you're, how do you know you're actually as smart as you think you are? Like, how do you know you're going to be able to accomplish this dream? You have this ambition.

• 1:15:26Andrew D. Huberman?

  You sort of don't, but you're, you're kind of pulling on a, on a string, hoping that there's a bigger ball of yarn.

• 1:15:33Lex Fridman?

  Yeah, but you have this kind of intuition. I, I've, I think I pride myself in knowing what I'm good at. Because the reason I have that intuition is because I think I'm very good at knowing all the things I suck at, which is basically everything. So like, whenever I notice, like, wait a minute, I'm kind of good at this, which is very rare for me. I think like that, that might be a ball of yarn worth pulling at. And the thing with, in terms of engineering, systems that are able to interact with humans. I think I'm very good at that. And because we talk about podcasting and so on, I don't know if I'm very good at podcasting.

• 1:16:13Andrew D. Huberman?

  You're very good at podcasting.

• 1:16:15Lex Fridman?

  But I certainly don't, I think maybe it is compelling to, for people to watch a kind-hearted idiot struggle with this, with this form. Maybe that's what, what's compelling. But in terms of like actual being a good engineer of human robot interaction systems. I think I'm good, but it's hard to know until you do it. And then the world keeps telling you, you're not. And it's just, it's full of doubt. It's really hard. And I've been struggling with that recently. It's, it's kind of a fascinating struggle, but then that's where the Goggins thing comes in is like.

• 1:16:52Lex Fridman?

  Aside from the stay hard motherfucker is the uh like whenever you're struggling that's a good sign that if you keep going that you're going to be alone in the success, right? Like um

• 1:17:05Andrew D. Huberman?

  Well, in your case, however, I I agree. And actually, David had a post recently that I thought was among his many brilliant posts was one of the more brilliant about how um you know, he talked about this myth of the light at the end of the tunnel. And instead, what he replaced that myth with was a concept that eventually your eyes adapt to the dark. Uh that the tunnel, it's not about a light at the end, that it's really about adapting to the dark of the tunnel. It's very Goggins.

• 1:17:33Lex Fridman?

  I love him so much.

• 1:17:34Andrew D. Huberman?

  Yeah, you you guys share a lot and uh a lot in common, uh knowing you both a bit, um you know, share a lot in common. But in this this loneliness and the and the pursuit of this dream, it seems to me it has a certain component to it that is extremely valuable, which is that the loneliness itself could serve as a driver to build the companion for the journey.

• 1:18:00Lex Fridman?

  Well, I'm very deeply aware of that. So like some people can uh make, because I talk about love a lot. I really love everything in this world and but I also love humans, friendship and uh romantic, you know, like even the cheesy stuff um. Just

• 1:18:21Andrew D. Huberman?

  You like romantic movies.

• 1:18:22Lex Fridman?

  Yeah.

• 1:18:22Andrew D. Huberman?

  Lex, let's just not, I'm just kidding.

• 1:18:24Lex Fridman?

  It's uh well, I got so much shit from Rogan about like uh was it the tango scene from uh Scent of a Woman? But yes, I find like a woman, there's nothing better than a woman in a red dress, like a uh uh you know, just like classy.

• 1:18:39Andrew D. Huberman?

  You should move to Argentina, my friend. You know, my father is Argentine. And you know what he said when I uh when I went on your podcast for the first time, he said he dresses well, because in Argentina, the men go to a wedding or a party or something. You know, in the US, they by halfway through the night, 10 minutes in the night, all the jackets are off. It looks like everyone's undressing for the party they just got dressed up for. And he said uh and he said, you know, I like the way he dresses. And then when I started, he was talking about you. And then when he when I started my podcast, he said, why don't you wear a a real suit like your friend Lex?

• 1:19:10Lex Fridman?

  I remember that.

• 1:19:11Andrew D. Huberman?

  In any case, um, but let's talk about um, this, this pursuit just a bit more because I think what you're talking about is, is building a, not just a solution for loneliness, but you've alluded to the loneliness as itself, an important thing. And I think you're right. I think within people, there is a caverns of thoughts and shame, but also just the desire to be, um, to have resonance, to, to be seen and heard. And I don't even know that it's seen and heard through language. But these reservoirs of loneliness, I think, um, they're, well, they're interesting. Maybe you could comment a little bit about it because just as often as you talk about love, I haven't

• 1:19:55Andrew D. Huberman?

  quantified it, but it seems that you talk about this loneliness. And maybe you just would, if you're willing, you could, you share a little bit more about that and, and what, what that feels like now in the pursuit of building this robot, human relationship. You've been, let, let me be direct. You've been spending a lot of time on building a robot, human relationship. Where's that at?

• 1:20:18Lex Fridman?

  Oh, wow. Uh, in terms of business and in terms of systems?

• 1:20:23Andrew D. Huberman?

  No, I'm talking about a specific robot.

• 1:20:25Lex Fridman?

  Oh, Rob. So, okay, I should, I should mention a few things. So one is there's a startup where there's an idea where I hope millions of people can use. And then there's my own personal, like, uh, almost like Frankenstein explorations with a, with particular robots. So I'm very fascinated with the legged robots in my own, uh, private, sounds like dark, but like in one, N of one experiments to see if I can recreate the magic. And, uh, that's been, I have a lot of really good already, the perception systems and control systems that are able to communicate affection

• 1:21:09Lex Fridman?

  in a dog-like fashion. So I'm, I'm in a really good place there. The stumbling blocks, which also have been part of my sadness recently, is, uh, that I also have to work with robotics companies that, um, you know, I gave so much of my heart, soul and love and appreciation towards Boston Dynamics, but.

• 1:21:29Lex Fridman?

  Boston Dynamics is also, you know, is a company that has to make a lot of money and they have marketing teams and they're like looking at this silly Russian kid in a suit and tie. It's like, what's he trying to do with all this love and robot interaction and dancing and so on? So there was a, I think, let's say for now, it's like when you break up with a girlfriend or something. Right now, we decided to part ways on this particular thing. They're huge supporters of mine. They're huge fans, but on this particular thing, Boston Dynamics is not focusing on or interested in human robot interaction. In fact, their whole business currently is keep the robot as far away from humans as possible. Uh, because it's in the industrial setting where it's doing

• 1:22:14Lex Fridman?

  monitoring in dangerous environments. It's almost like a remote security camera essentially is its application. To me, I thought, uh, it's still even in those applications exceptionally useful for the robot to be able to perceive humans, like see humans and to be able to, uh, in a big map localize where those humans are and have human intention. For example, like this, I did this a lot of work with pedestrians for a robot to be able to anticipate what the hell the human is doing, like where it's walking. If you're, it's, humans are not ballistics object. They're not, just because you're walking this way one moment, doesn't mean you'll keep walking that direction. You have to infer a lot of signals, especially the head movement and the

• 1:22:56Lex Fridman?

  eye movement. And so I thought that's super interesting to explore, but, uh, they didn't feel that. So I'll be working with a few other robotics companies that, uh, are, are, um, much more open to that kind of stuff and they're super excited and fans of mine. And hopefully Boston Dynamics, my first love, they're getting back with an ex-girlfriend will come around. But so the algorithmically, it's, uh, I'm basically, uh, done there. Uh, the, the rest is actually getting, um, some of these companies to work with. And then there's a, uh, for people who'd work with robots know that one thing is to write software that works and the other is to have a real machine that actually works. And it breaks down in all kinds of different ways that are fascinating.

• 1:23:41Lex Fridman?

  And so there's a big challenge there, but that's almost, um, It may sound a little bit confusing in the context of our previous discussion, because the previous discussion was more about the big dream, how I hoped to have millions of people enjoy this moment of magic. The current discussion about a robot is something I personally really enjoy, it just brings me happiness. I really try to do now everything that just brings me joy, maximize that, because robots are awesome. But two, given my little bit growing platform, I want to use the opportunity to educate people. It's just, it's like, robots are cool, and if I think they're cool, I'll be able to,

• 1:24:26Lex Fridman?

  I hope, be able to communicate why they're cool to others. So this little robot experiment is a little bit of research project, too. There's a couple of publications with MIT folks around that. But the other is just to make some cool videos and explain to people how they actually work. And as opposed to people being scared of robots, they can be, they could still be scared, but also excited. Like, see the dark side, the beautiful side, the magic of what it means to bring, you know, for a machine to become a robot. I want to inspire people with that. But that's less, it's interesting, because I think the big impact in terms of the dream

• 1:25:10Lex Fridman?

  does not have to do with embodied AI, so it does not need to have a body. I think the refrigerator is enough that for an AI system, just to have a voice and to hear you, that's enough for loneliness. The embodiment is just... By embodiment, you mean the physical structure? Physical instantiation of intelligence. So it's a legged robot, or even just a thing, I have a few other humanoid robot, a little humanoid robot, maybe I'll keep him on the table. It's like walks around, or even just like a mobile platform that can just like turn around and look at you. It's like we mentioned with the pen, something that moves and can look at you. It's like that butter robot that asks, what is my purpose?

• 1:26:01Lex Fridman?

  That that is really, it's almost like art. There's something about a physical entity that moves around, that's able to look at you and interact with you, that makes you wonder what it means to be human. It like challenges you to think, if I, if that thing looks like it has consciousness, what the hell am I? And I like that feeling. I think that's really useful for us. It's humbling for us humans. But that's less about research. It's certainly less about business and more about exploring our own, our own selves. And challenging others to think like, to, to think about what makes them human.

• 1:26:42Andrew D. Huberman?

  I love this desire to share the delight of an interaction with a robot. And as you describe it, I actually, I find myself starting to crave that because we all have those elements from childhood where, or from adulthood, where we experience something, we want other people to feel that. And I think that you're right. I think a lot of people are scared of AI. I think a lot of people are scared of robots. My only experience of a robotic like thing is my Roomba vacuum, where it goes about, actually was pretty good at picking up Costello's hair when he was shed. And then, and I was grateful for it. But then when it would, when I was on a call or something and it would get caught on a, on a wire or something, I would find myself getting upset with the Roomba in that moment. I'm like, what are you doing?

• 1:27:26Andrew D. Huberman?

  You know, and I, and obviously it's just doing what it does. But, but that's a kind of mostly positive, but slightly negative interaction. But what you're describing has so much more richness and layers of detail that I can only imagine what those relationships are like.

• 1:27:43Lex Fridman?

  Well, there's a few, just a quick comment. So I've had, they're currently in Boston. I have a bunch of Roombas for my robot. And I did this experiment.

• 1:27:51Andrew D. Huberman?

  Wait, how many Roombas? Sounds like a fleet of Roombas.

• 1:27:56Lex Fridman?

  So probably seven or eight.

• 1:27:58Andrew D. Huberman?

  Wow, that's a lot of Roombas. This place is very clean.

• 1:28:02Lex Fridman?

  Well, so this, I'm kind of waiting. This, this is, the place we're currently in in Austin is way larger than I need. But it's I basically got it so to make sure I have room for robots.

• 1:28:17Andrew D. Huberman?

  So you're gonna so you have these seven or so Roombas you deploy all seven at once?

• 1:28:22Lex Fridman?

  Oh, no, I do different experience with them, uh, different experiments with them. So one of the things I want to mention is this is a, I think there was a YouTube video that inspired me to try this. Is, uh, I got them to, uh, to scream in pain and moan in pain. Um, whenever they, uh, were kicked or contacted. And I did that experiment to see how I would feel. I, I meant to do like a YouTube video on it, but then it just seemed very cruel.

• 1:28:50Andrew D. Huberman?

  Did any Roomba rights activists come at you?

• 1:28:53Lex Fridman?

  Like, I, I think if I release that video, I think it's gonna make me look insane, which I, I know people know I'm already insane.

• 1:29:02Andrew D. Huberman?

  Now you, now you have to release the video.

• 1:29:05Lex Fridman?

  Sure, well, I, I think maybe if I contextualize it by showing other robots of like to show why this is fascinating. Because ultimately I felt like they were human almost immediately. And that display of pain was, uh, what did that?

• 1:29:20Andrew D. Huberman?

  Giving them a voice.

• 1:29:21Lex Fridman?

  Giving them a voice, especially a voice of, um, dislike of, of pain.

• 1:29:27Andrew D. Huberman?

  I have to connect you to my friend Eddie Chang. He studies speech and language. He's a neurosurgeon and we're lifelong friends. He, uh, studies speech and language, but he described some of these, um, more primitive visceral vocalizations, cries, groans, moans of delight, um, other sounds as well, use your imagination, as such powerful rudders for the other, for the emotions of other people. And so I find it fascinating, um, I can't wait to see this video. Is that, so is the video available online?

• 1:29:59Lex Fridman?

  No, I haven't, uh, I haven't recorded it. I just hit a bunch of Roombas that are able to scream in pain, um, in my Boston, uh, in my Boston place. So I, I, like, people are ready as

• 1:30:11Andrew D. Huberman?

  Next, next podcast episode with Lex, maybe we'll have that one, who knows?

• 1:30:16Lex Fridman?

  So the thing is, like, people, I, I've noticed, because I talk so much about love, and it's really who I am, I think they wanna, it, to a lot of people, it seems like there's, there's, there gotta be a dark person in there somewhere. And I thought if I released videos of Roomba screaming, and they're like, yep, yep, that guy is definitely insane.

• 1:30:34Andrew D. Huberman?

  What about, um, like, shouts of glee and delight? You could do that, too, right?

• 1:30:38Lex Fridman?

  I, well, I don't know how to, I don't, how to, to me, delight is quiet, right?

• 1:30:44Andrew D. Huberman?

  You're Russian. Americans are much, Americans are much louder than Russians.

• 1:30:49Lex Fridman?

  Yeah, yeah, but I don't, I mean, unless you're talking about, like, I don't know how you would have sexual relations with a Roomba.

• 1:30:57Andrew D. Huberman?

  Well, I wasn't necessarily saying, uh, sexual delight, but, um,

• 1:31:00Lex Fridman?

  Trust me, I tried. I'm just kidding. That's a joke, internet. Okay. But I was fascinated in the psychology of how little it took, because you mentioned you had a negative relationship with the Roomba.

• 1:31:11Andrew D. Huberman?

  Only, well, I'd find that mostly I took it for granted.

• 1:31:14Lex Fridman?

  Yeah.

• 1:31:15Andrew D. Huberman?

  It just served me. It collected Costello's hair, and then when it would do something I didn't like, I would get upset with it. So that's not a good relationship. It was taken for granted, and I would get upset, and then I'd park it again, and I'd just, like, you're, you're in the, in the corner.

• 1:31:28Lex Fridman?

  Yeah, but there's a way to frame its, uh, it being quite dumb as, uh, almost cute. You know, you're almost connecting with it for its dumbness, and I think that's an artificial intelligence problem.

• 1:31:44Andrew D. Huberman?

  Interesting.

• 1:31:45Lex Fridman?

  I think flaws are, should be a feature, not a bug.

• 1:31:49Andrew D. Huberman?

  So along the lines of this, um, the different sorts of relationships that one could have with robots, and the fear, but also that some of the positive relationships that one could have, there's so much dimensionality there, so much to explore. But power dynamics in relationships are very interesting because the obvious ones that the unsophisticated view of this is, you know, one, there's a master and a servant, right? But there's also manipulation, there's benevolent manipulation, you know, children do this with parents, puppies do this, puppies turn their head and look cute and maybe give out a little little noise, kids, koo, and parents always think that they're, you know, they're doing

• 1:32:31Andrew D. Huberman?

  this because, you know, they, they love the parent, but in many ways, studies show that those koo's are ways to extract the sorts of behaviors and expressions from the parent that they want. The child doesn't know it's doing this, it's completely subconscious, but it's benevolent manipulation. So there's one version of fear of robots that I hear a lot about, that I think most people can relate to, where the robots take over and they become the masters and we become the servants. But there could be another version that, you know, in certain communities that I'm certainly not a part of, but they call topping from the bottom, where the robot is actually manipulating you into doing things, but you are under the belief that you are in charge,

• 1:33:16Andrew D. Huberman?

  but actually they're in charge. And so I think that's one that, if we could explore that for a second, you could imagine it wouldn't necessarily be bad, although it could lead to bad things. The reason I want to explore this is I think people always default to the extreme, like the robots take over and we're in little jail cells and they're out having fun and ruling the universe. What, what sorts of manipulation can a robot potentially carry out, good or bad?

• 1:33:46Lex Fridman?

  Yeah, so there's a lot of good and bad manipulation between humans, right? Just like you said.

• 1:33:54Lex Fridman?

  To me,

• 1:33:57Lex Fridman?

  especially, like you said, topping from the bottom, is that the term?

• 1:34:01Andrew D. Huberman?

  So I think someone from MIT told me that term. Wasn't Lex.

• 1:34:07Lex Fridman?

  I think, so first of all, there's power dynamics in bed and power dynamics in relationships and power dynamics on the street and in the work environment. Those are all very different.

• 1:34:19Lex Fridman?

  I think,

• 1:34:21Lex Fridman?

  I think power dynamics can make human relationships, especially romantic relationships, fascinating and rich and fulfilling and exciting and all those kinds of things. So I don't,

• 1:34:36Lex Fridman?

  I don't think in themselves they're bad. And the same goes with robots. I really love the idea that a robot will be a top or a bottom in terms of like power dynamics. And I think everybody should be aware of that. And the manipulation is not so much manipulation, but a dance of like pulling away, a push and pull and all those kinds of things. In terms of control, I think we're very, very, very far away from AI systems that are able to lock us up. They, to lock us up in, you know, like to have so much control that we basically cannot live our lives in the way that we want.

• 1:35:16Lex Fridman?

  I think there's, in terms of dangers of AI systems, there's much more dangers that have to do with autonomous weapon systems and all those kinds of things. So the power dynamics as exercised in the struggle between nations and war and all those kinds of things. But in terms of personal relationships, I think power dynamics are a beautiful thing. Now, there is, of course, going to be all those kinds of discussions about consent and rights and all those kinds of things.

• 1:35:43Andrew D. Huberman?

  Well, here we're talking, I always say, you know, in any discussion around this, if we need to define really the context, it's always, it always should be consensual, age appropriate, context appropriate, species appropriate. But now we're talking about human robot interactions and so I guess that.

• 1:36:00Lex Fridman?

  No, I actually was trying to make a different point, which is I do believe that robots will have rights down the line. And I think in order for, in order for us to have deep meaningful relationship with robots, we would have to consider them as entities in themselves that deserve respect.

• 1:36:19Lex Fridman?

  That's a really interesting concept that I think people are starting to talk about a little bit more, but it's very difficult for us to understand how entities that are other than human, I mean, the same as with dogs and other animals can have rights on a level as humans.

• 1:36:34Andrew D. Huberman?

  Well, that, yeah, I mean, we, we can't and nor should we do whatever we want with animals. We have a USDA, we have departments of agriculture that deal with, you know, animal care and use committees for research for, you know, for farming and ranching and all that. So I, I, while, when you first said it, I thought, wait, why would have, there'd be a bill of robotic rights, but it absolutely makes sense in the context of everything we've been talking about up until now. Let's, if you're willing, I'd love to talk about dogs because you've mentioned dogs a couple of times, a robot dog. You had a biological dog.

• 1:37:15Lex Fridman?

  Yeah, I had a Newfoundland named Homer for many years, growing up.

• 1:37:24Andrew D. Huberman?

  In Russia or in the US?

• 1:37:25Lex Fridman?

  In the United States. And he was about, he was over 200 pounds. It's a big dog.

• 1:37:30Andrew D. Huberman?

  That's a big dog.

• 1:37:31Lex Fridman?

  If people know, people know Newfoundland, so he's this black dog that's really long hair and just a kind. So I think perhaps that's true for a lot of large dogs, but he thought he was a small dog. So he moved like that and.

• 1:37:46Andrew D. Huberman?

  Was he your dog?

• 1:37:47Lex Fridman?

  Yeah, yeah.

• 1:37:48Andrew D. Huberman?

  So you had him since he was fairly young?

• 1:37:50Lex Fridman?

  Since, yeah, since the very, very beginning to the very, very end. And one of the things, I mean, he had this kind of, we mentioned like Roombas. He had a kind-hearted dumbness about him that was just overwhelming. It's part of the reason I named him Homer because it's after Homer Simpson, in case people are wondering which Homer I'm referring to. I'm not, you know, so there's.

• 1:38:18Andrew D. Huberman?

  A deep odyssey.

• 1:38:20Lex Fridman?

  Exactly. There's a clumsiness that was just something that immediately led to a deep love for each other. And one of the.

• 1:38:31Lex Fridman?

  I mean, he was always, it's a shared moments. He was always there for so many nights together. That's a, that's a powerful thing about a dog that, um, he was there through all the loneliness, through all the tough times, through the successes and all those kinds of things. And I remember, um, I mean, that was a really moving moment for me. I still miss him to this day. How long ago did he die? Um, maybe 15 years ago. So it's, it's been a while, but it was the first time I've really experienced, like, the feeling of death. So what happened is, uh, he, uh, he got cancer.

• 1:39:12Lex Fridman?

  And so he was dying slowly and then at a certain point, he couldn't get up anymore. Uh, there's a lot of things I could say here, uh, you know, that I struggle with that maybe, uh, maybe he suffered much longer than he needed to. That's something I really think about a lot. But I remember I had to take him to the hospital and the nurses couldn't carry him, right? So you talk about a 200 pound dog. I was really into powerlifting at the time. I remember like they, they, they tried to figure out all these kinds of ways to, uh, so in order to put him to sleep, they had to take him, um,

• 1:39:55Lex Fridman?

  into, into a room. And so I had to carry him everywhere. And here's this dying friend of mine that I just had to, uh, first of all, it's really difficult to carry somebody that heavy when they're not helping you out. And, um, yeah, so I remember it was the first time seeing a friend laying there and seeing life drain from his body.

• 1:40:24Lex Fridman?

  And that realization that we're here for a short time was made so real. That here's a friend that was there for me the week before, the day before, and now he's gone. And that was, um, I don't know, that that spoke to the fact that you could be deeply connected with a dog. Also spoke to the fact that, uh, the, the shared moments together that led to that deep friendship is, um,

• 1:40:54Lex Fridman?

  are, will make life so amazing. But also spoke to the fact that death is a motherfucker.

• 1:41:03Lex Fridman?

  So I know you've lost Costello recently.

• 1:41:05Andrew D. Huberman?

  Yeah.

• 1:41:06Lex Fridman?

  And you've been going.

• 1:41:06Andrew D. Huberman?

  And as you're saying this, I'm definitely fighting back the tears. I, um, I, uh, thank you for sharing that, that, uh, I guess we're about to both cry over our dead dogs. That it was, it was bound to happen, just given when this is, when this is happening. Yeah, it's, uh.

• 1:41:25Lex Fridman?

  How long, how long did you know that Costello was not doing well?

• 1:41:28Andrew D. Huberman?

  Um, well, let's see, a year ago, during the start of, about six months into the pandemic, he started getting abscesses and he was not, his behavior changed and something really changed. And then, um, I put him on testosterone because, uh, which helped a lot of things. It certainly didn't cure everything, but it helped a lot of things. He was dealing with joint pain, sleep issues. And then it just became a very slow decline. To the point where, you know, two, three weeks ago, he had, you know, a closet full of medication. I mean, this dog was, you know, it was like a pharmacy. It's amazing to me when I looked at it the other day, still haven't cleaned up and removed all his things

• 1:42:12Andrew D. Huberman?

  because I can't quite bring myself to do it, but, um. Do you think he was suffering? Well, so what happened was about a week ago, it was really just about a week ago, it's amazing. He was going up the stairs, I saw him slip. He was a big dog, he wasn't 200 pounds, he was about 90 pounds, he's a bulldog, that's pretty big, and he was fit.

• 1:42:31Andrew D. Huberman?

  And then I noticed that he wasn't carrying a foot in the back like it was injured, it had no feeling at all. He never liked me to touch his hind paws, and I could do, that thing was just flopping there. And then the vet found some spinal degeneration, and I was told that the next one would go. Did he suffer? Sure hope not, but something changed in his eyes. Yeah. It's the eyes again, I know you and I spend long hours on the phone and talking about like the eyes and how, what they convey and what they mean about internal states and forsake of robots and biology of other kinds, but. Do you think something about him was gone in his eyes? I, I think he was real, here I am anthropomorphizing.

• 1:43:12Andrew D. Huberman?

  I think he was realizing that one of his great joys in life, which was to walk and sniff and pee on things.

• 1:43:23Andrew D. Huberman?

  This dog. The fundamentals. Loved to pee on things, it was amazing. I wondered where he put it, he was like a reservoir of urine, it was incredible. I think, oh, that's it, he's just, he'd put like one drop on the 50 millionth plant, and then we get to the 50 millionth and one plant, and he'd just have, you know, leave a puddle, and here I am talking about Costello peeing. He was losing that ability to stand up and do that, he was falling down while he was doing that. And I, I do think he started to realize, and the, the passage was easy and peaceful, but,

• 1:43:56Andrew D. Huberman?

  you know, I'll say this, I'm not ashamed to say it, I mean, I wake up every morning since then, just, I, I don't even make the conscious decision to allow myself to cry, I wake up crying. And I'm fortunately able to make it through the day, thanks to the great support of my friends and, and you and my family, but,

• 1:44:13Andrew D. Huberman?

  I miss him, man. You miss him? Yeah, I miss him, and I feel like, uh, he, you know, Homer, Costello, you know, the relationship to one's dog is so specific, but.

• 1:44:24Andrew D. Huberman?

  So that, that part of you is gone.

• 1:44:27Andrew D. Huberman?

  That's the hard thing. You know.

• 1:44:34Andrew D. Huberman?

  What's, what, what I think is different is that I made the mistake, I think. Well, I hope it was a good decision, but sometimes I think I made the mistake of I brought Costello a little bit to the world through the podcast, through posting about him. I gave, I answered for more advice about him in public. Let's be honest, I have no idea what his mental life was or his relationship to me. And I'm just exploring all this for the first time because he was my first dog, but I raised him since he was seven weeks.

• 1:44:59Lex Fridman?

  Yeah, you gotta hold it together. I, I noticed the episode, you released on Monday. You mentioned Costello, like you, you brought him back to life for me for that brief moment.

• 1:45:10Andrew D. Huberman?

  Yeah, but he's, he's, he's gone.

• 1:45:12Lex Fridman?

  Well, that's the, he's gonna be gone for a lot of people too.

• 1:45:18Andrew D. Huberman?

  Well, this is what I'm struggling with. I think that maybe, you're pretty good at this. Have you done this before? This is the challenge is I actually, part of me, I know how to take care of myself pretty well.

• 1:45:32Lex Fridman?

  Yeah.

• 1:45:33Andrew D. Huberman?

  Not perfectly, but pretty well. And I have good support. I, I do worry a little bit about how it's gonna land and how people will feel. I'm, I'm concerned about their internalization. So that's something I'm still, I'm still iterating on.

• 1:45:46Lex Fridman?

  And you have to, they have to watch you struggle, which is fascinating.

• 1:45:49Andrew D. Huberman?

  Right. And I've mostly been shielding them from this, but what would make me happiest if, is if people would internalize some of Costello's best traits and his best traits were that he was incredibly tough. I mean, he was a, you know, 22 inch neck bulldog, the whole thing. He was just born that way. But was, what was so beautiful is that his toughness is never what he rolled forward. It was just how sweet and kind he was. And so if people can take that, then, um, then there's a win in there someplace. So.

• 1:46:22Lex Fridman?

  I, I think there's some ways in which you should probably live on in your podcast too. You should, uh, I mean, it's such a, one of the things I loved about, uh, his role in your podcast is that he brought so much joy to you. We mentioned the robots, right? I think, uh, that's such a powerful thing to bring that joy into, like, allowing yourself to experience that joy, to bring that joy to others, to share it with others. Uh, that's really powerful. And I mean, not to, this is, this is like the Russian thing is, um,

• 1:46:59Lex Fridman?

  It touched me when Louis CK had that moment that I keep thinking about in his show Louis, where like an old man was criticizing Louis for whining about breaking up with his girlfriend. And you're saying like the most, the most beautiful thing about love, the song that's catchy now, that's now making me feel horrible saying it, but like is the loss. The loss really also is making you realize how much that person, that dog meant to you. And like allowing yourself to feel that loss and not run away from that loss is really powerful.

• 1:47:41Lex Fridman?

  And in some ways, that's also sweet, just like the love was, the loss is also sweet. Because you know that you felt a lot for that, for your friend. So I, you know, and then continue bringing that joy. I think it would be amazing to the podcast. I hope to do the same with, with robots or whatever else is the source of joy, right? And maybe, do you think about one day getting another dog?

• 1:48:12Andrew D. Huberman?

  Yeah, in time. You're hitting on all the key buttons here. I want that to, we're thinking about, you know, ways to kind of immortalize Costello in a way that's real, not just, you know, creating some little logo or something silly. You know, Costello, much like David Goggins is a person, but Goggins also has grown into kind of a verb, you're gonna Goggins this, or you're gonna, and there's an adjective, like that's extremely like it. I think that for me, Costello was all those things. He was a, he was a being, he was his own being. He was a noun, a verb, and an adjective. So, and he had this amazing superpower that I wish I could get, which is this ability

• 1:48:54Andrew D. Huberman?

  to get everyone else to do things for you without doing a damn thing. The Costello effect, as I call it.

• 1:49:00Lex Fridman?

  So it's an idea, I hope he lives on.

• 1:49:02Andrew D. Huberman?

  Yes. Thank you for that. This actually has been very therapeutic for me. Which, which actually brings me to a question. We're friends, we're not just co-scientists, colleagues, working on a project together and, and in the world.

• 1:49:23Andrew D. Huberman?

  That's somewhat similar. Just, just. Two, two dogs. Just two dogs, basically.

• 1:49:30Andrew D. Huberman?

  But let's talk about friendship.

• 1:49:34Andrew D. Huberman?

  Because I think that, I certainly know as a scientist, that there are elements that are very lonely of the scientific pursuit. There are elements of many pursuits that are lonely. Music, math always seemed to me like they're like the loneliest people. Who knows if that's true or not. Also, people work in teams and sometimes people are surrounded by people, interacting with people, and they feel very lonely. But for me, and I, and I think as well for you, friendship is an incredibly strong force in making one feel like certain things are possible or worth reaching for. Maybe even making us compulsively reach for them.

• 1:50:18Andrew D. Huberman?

  So when you were growing up, you grew up in Russia until what age?

• 1:50:22Lex Fridman?

  Thirteen.

• 1:50:23Andrew D. Huberman?

  Okay. And then, and then you moved directly to Philadelphia?

• 1:50:28Lex Fridman?

  To Chicago.

• 1:50:29Andrew D. Huberman?

  Chicago.

• 1:50:29Lex Fridman?

  And then Philadelphia, you know, and then San Francisco and Boston and so on. But really to Chicago, that's when I went to high school.

• 1:50:38Andrew D. Huberman?

  Do you have siblings?

• 1:50:39Lex Fridman?

  Brother, older brother.

• 1:50:41Andrew D. Huberman?

  Most people don't know that.

• 1:50:43Lex Fridman?

  Yeah, he is a very different, very different person. But somebody I definitely look up to. So he's a wild man. He's extrovert. He's, he was into, I mean, so he's, he's also a scientist, a bioengineer. But he's, when we were growing up, he was the person who, you know, did, drank and did every drug and, but also was the life of the party. And, and I just thought he was the, you know, when you're the older brother, five years older, he was the coolest person that, you know, I always wanted to be him. So to that, he was, he definitely had a big influence.

• 1:51:21Lex Fridman?

  But I think for me, in terms of friendship, growing up, I had, I had one really close friend. And then when I came here, I had another close friend, but I'm very. I believe, uh, I don't know if I believe, but I draw a lot of strength from deep connections with, uh, with other people and just a small number of people, just a really small number of people. That's when I moved to this country, I was really surprised how like, uh, there were these, be these, uh, large groups of friends, quote unquote, but they, the, the, the depth of connection was not there at all from my sort of perspective. Now, I, I moved

• 1:52:05Lex Fridman?

  to the suburb of Chicago, it was Naperville. It's more like a middle class, maybe upper middle class. So it's like people that, uh, cared more about material possessions than deep human connection. So that added to the thing. But I, I drew more meaning than almost anything else was from friendship. Early on, I had a best friend. His name was, his name is Yura. Uh, I don't know how to say it in English. Uh, how do you say it in Russian? Yura. What's his last name? Do you remember? Uh, Mirkoev. Uh, Yura Mirkoev. Uh, so we just spent all our time together. There's,

• 1:52:46Lex Fridman?

  there's a, there's also a group of friends, like, I don't know, it's like eight guys. In Russia, growing up, it's, uh, like, parents didn't care if you're coming back at a certain hour. So we'd spend all day, all night, just playing soccer, usually called football, uh, and just talking about life and all those kinds of things, even at that young age. The, I think people in Russia, in Soviet Union, grow up much quicker. Uh, I think the education system at the university level is world-class in the United States in terms of like really creating really, uh, big, powerful minds. Um, at least it used to be,

• 1:53:30Lex Fridman?

  but I think that they aspire to that. But the education system for like, for younger kids in the Soviet Union was incredible. Like, they did not treat us as kids. We, the, the level of literature, Tolstoy, Dostoevsky, When you were just a small child? Yeah. Amazing. You're in like the level of mathematics and you're made to feel like shit if you're not good at mathematics. Like we, I think in this country, there's more like especially young kids because they're so cute. Like they're being babied. We only start to really push adults later in life. Like, so if you want to be the best in the world at this, then you get to be pushed. But we were pushed at a young age. Everybody was pushed and that brought out the best in people.

• 1:54:15Lex Fridman?

  I think they really forced people to discover, like discover themselves in the Goggins style, but also discover what they're actually passionate about, what they're not. Was this true for boys and girls where they pushed equally there? Yeah, they were pushed. Yeah, they were pushed equally, I would say. There was a, obviously there was more, not obviously, but there, at least from my memories, more of, what's the right way to put it? But there was like gender roles, but not in a negative connotation. It was, it was the red dress versus the suit and tie kind of connotation, which is like,

• 1:54:51Lex Fridman?

  there's, you know, like guys like lifting heavy things and girls like creating beautiful art. And, you know, like there's. A more traditional view of gender, more nineteen fifty, sixties. But we didn't think in terms of, at least at that age, in terms of like roles and then like a homemaker or something like that, or no, it was more about what people care about. Like, uh, girls cared about this set of things and guys cared about this set of things. I think mathematics and engineering was something that guys cared about and sort of, at least my perception of that time. And then girls create about, girls cared about beauty.

• 1:55:34Lex Fridman?

  So like guys want to create machines, girls want to create beautiful stuff. And now, of course, that I don't take that forward in some kind of philosophy of life, but it's just the way I grew up and the way I remember it. But all, everyone worked hard. The, the value of hard work was instilled in everybody. And through that.

• 1:55:59Lex Fridman?

  I think it's a little bit of hardship. Of course, also economically, everybody was poor, especially with the collapse of the Soviet Union. There's poverty everywhere. You didn't notice it as much, but there was a, because there's not much material possessions. There was a huge value placed on human connection. Just meeting with neighbors, everybody knew each other. We lived in an apartment building, very different than you have in the United States these days. Everybody knew each other. You know, you would get together, drink vodka, smoke cigarettes and play guitar and sing sad songs about, about life.

• 1:56:37Andrew D. Huberman?

  What's with the sad songs and the Russian thing? I mean, Russians do express joy from time to time.

• 1:56:45Lex Fridman?

  Yeah, they do.

• 1:56:45Andrew D. Huberman?

  Certainly you do. But what do you think that's about? Is it because it's cold there? But it's cold other places, too.

• 1:56:54Lex Fridman?

  I think, so first of all, the Soviet Union, the echoes of World War II and the millions and millions and millions of people, civilians that were slaughtered. And also starvation is there, right? So like the echoes of that, of the ideas, the literature, the art is there. Like that's grandparents, that's parents, that's all there. So that contributes to it, that life can be absurdly, unexplainably cruel. At any moment, everything can change. So that's in there. Then I think there's an empowering aspect to finding beauty in suffering, that then everything else is beautiful, too. Like if you just linger, it's like why you meditate on death.

• 1:57:39Lex Fridman?

  It's like if you just think about the worst possible case and find beauty in that, then everything else is beautiful, too. And so you write songs about the dark stuff. And that somehow helps you deal with whatever comes. There's a hopelessness to the Soviet Union that like, you know, inflation, all those kinds of things where people were sold dreams and never delivered. And so like, there's a, if you don't sing songs about sad things, you're going to become cynical about this world.

• 1:58:14Andrew D. Huberman?

  Interesting.

• 1:58:14Lex Fridman?

  So they don't want to give in to cynicism. Now, a lot of people did, you know, one of the... But that is the battle against cynicism. One of the things that may be common in Russia is a kind of cynicism about, like if I told you the thing I said earlier about dreaming about robots, it's very common for people to dismiss that dream of saying, no, that's not, that's too wild. Like, who else do you know that did that? Or you want to start a podcast, like who else? Like, nobody's making money on podcasts. Like, why do you want to start a podcast? That kind of mindset, I think, is quite common, which is why I would say entrepreneurship in Russia is still not very good.

• 1:58:59Lex Fridman?

  Which, to be a business, like, to be an entrepreneur, you have to dream big. And you have to have others around you, like friends and support group that makes you, make you dream big. But if you don't give in to cynicism and appreciate the beauty in the unfairness of life, the absurd unfairness of life, then I think it just makes, uh, makes you appreciative of everything. It's like a, it's a prerequisite for gratitude. And so, um, yeah, I think that instilled in me ability to appreciate everything. Just like, everything, everything's amazing. And then also, there's a culture

• 1:59:41Lex Fridman?

  of romantic, of like, romanticizing everything. Like, it's almost like, uh, like romantic relationships were, were very like soap opera-like. It's very like, over-the-top dramatic. And I think, I think that was instilled in me too. Not only do I appreciate everything about life, but I get like, emotional about it. In a sense, like, I get like, a visceral feeling of joy for everything. And the same with, uh, you know, friends or people of the opposite sex, like, there's a deep, like, emotional connection there, that like,

• 2:00:22Lex Fridman?

  That's like way too dramatic to like, I guess, relative to what the actual moment is, but I derive so much deep, like dramatic joy from so many things in life. And I think I would attribute that to upbringing in Russia. But the thing that sticks most of all is the friendship. And I've now, since then, had one other friend like that in the United States. He lives in Chicago. His name is Matt. And slowly, here and there accumulating really fascinating people, but I'm very selective with that. Funny enough, the few times,

• 2:01:05Lex Fridman?

  you know, it's not few, it's a lot of times now, interacting with Joe Rogan. It's sounds surreal to say, but there was a kindred spirit there, like I've connected with him. And there's been people like that also in the grappling sports that I really connected with. I've actually struggled, which is why I'm so, I'm so glad to be your friend, is I've struggled to connect with scientists.

• 2:01:30Andrew D. Huberman?

  They can be a little bit wooden sometimes.

• 2:01:32Lex Fridman?

  Yeah.

• 2:01:33Andrew D. Huberman?

  Even the biologists. I mean, one thing that I, well, I'm so struck by the fact that you, you know, you work with robots, you're an engineer, AI, you know, science, technology, and that all sounds like hardware, right? But what you're describing, and I know is true about you, is this deep emotional life and this resonance. And it's, it's really wonderful. I actually think it's one of the reasons why so many people, scientists and otherwise, have gravitated towards you and your podcast is because you hold both elements. You know, in Herman Hesse's book, I don't know if you read Narcissus and Goldman, right? It's about these elements of the logical rational mind and the, the emotional mind and how those are woven together. And if people haven't read it, they should. And

• 2:02:15Andrew D. Huberman?

  you embody the, the full picture. And I think that's so much of what draws people to you.

• 2:02:19Lex Fridman?

  I've read every Herman Hesse book.

• 2:02:21Andrew D. Huberman?

  As usual, as usual, I've done about nine percent of what likes it. No, it's true. You mentioned Joe, who is a A phenomenal human being, not just for his amazing accomplishments, but for how he shows up to the world, one-on-one. I think I heard him say the other day on an interview. He said, there is no public or private version of him. He's like, this is, this is me. He said, it was beautiful. He said, I'm like the fish that got through the net. You know, there is no onstage, offstage version. And you're absolutely right. And I, so, but, well, you guys, I have a question actually about.

• 2:02:59Lex Fridman?

  But that's a really good point about public and private life. He was a huge, if I could just comment real quick. Like that, he was, I've been a fan of Joe for a long time, but he's been an inspiration to, to not have any difference between public and private life. I actually had a conversation with Naval about this. And he said that you can't have a rich life, like a exciting life, if you're the same person publicly and privately. And I think I understand that idea, but I don't agree with it. I, I think it's really fulfilling and exciting to be the same person privately and publicly,

• 2:03:41Lex Fridman?

  with very few exceptions. Now, that said, I don't have any really strange sex kinks. So like, I feel like I can be open with basically everything. I don't have anything I'm ashamed of. You know, there's some things that could be perceived poorly, like the screaming Roombas, but I'm not ashamed of them. I just have to present them in the right context. But there is, there's freedom to being the same person in private as in public. And that, Joe made me realize that you can, you can be that. And also to be kind to others. It sounds, it sounds kind of absurd, but I really, I really always enjoyed, like, being good to others.

• 2:04:28Lex Fridman?

  Like just being kind towards others. But I always felt like the world didn't want me to be. Like, there's so much negativity when I was growing up, like just around people. If you actually just notice how people talk. They uh from like complaining about the weather. This could be just like the big cities that I visited, but there's a general negativity. And positivity is kind of suppressed. You're not, one, you're not seen as very intelligent. And two, there's a kind of, you're seen as like a little bit of a weirdo. And so I always felt like I had to hide that. And what Joe made me realize, one, I have, I can be fully just the same person, private and public.

• 2:05:12Lex Fridman?

  And two, I can embrace being kind and just in the way that I like, in the way I I know how to do. And sort of for me, I'm like on Twitter. Uh, or like publicly, whenever I say stuff, that means saying stuff simply, almost to the point of cliche. And like, I have the strength now to say it, even if I'm being mocked. You know what I mean? Like, just, it's okay. If everything's going to be okay, okay, some people will think you're dumb. They're probably right. The point is, like, just enjoy being yourself. And that Joe, Joe more than almost anybody else, because he's so successful at it, uh, inspired me to do that. Be kind and be the same person, private and public.

• 2:05:56Andrew D. Huberman?

  I love it. And I, I love the idea that authenticity doesn't have to be oversharing, right? That it doesn't mean you reveal every detail of your life, what, you know, it, it's a way of being true to an essence of oneself.

• 2:06:08Lex Fridman?

  Right. You're not, there's never a feeling when you deeply think and introspect that you're hiding something from the world. Or you're being dishonest in some fundamental way. So, uh, yeah, that, that, uh, that's truly liberating. It allows you to think, it allows you to, uh, like, think freely, to speak freely, to, um, just to be freely. That said, it's not like, you know.

• 2:06:37Lex Fridman?

  It's not like there's not still a responsibility to be the best version of yourself. So, you know, I'm very careful with the way I say something. So the whole point, it's not so simple to express the spirit that's inside you with words. It depends, I mean, some people are much better than others. I struggle, like oftentimes when I say something and I hear myself say it, it sounds really dumb and not at all what I meant. So that's the responsibility you have. It's not just like being the same person publicly privately means you can just say whatever the hell. It means there's still a responsibility to try to be, to express who you truly are. And that, that's, that's, uh, that's hard.

• 2:07:22Andrew D. Huberman?

  It is hard and I think that, you know, we have this pressure, all people, when I say we, I mean, all, all humans, and maybe robots too, feel this pressure to be able to express ourselves in that one moment, in that one form. And it is beautiful, beautiful when somebody, for instance, can capture some essence of love or sadness or anger or something in a song or in a poem or in a short quote. But perhaps it's also possible to do it in aggregate, you know, all, all the things, you know, how you show up. Your, for instance, one of the things that initially drew me to want to get to know you as a human being and a scientist,

• 2:08:01Andrew D. Huberman?

  and eventually we became friends, was the level of respect that you brought to your podcast listeners by wearing a suit.

• 2:08:09Lex Fridman?

  Yeah.

• 2:08:09Andrew D. Huberman?

  I'm being serious here, you know?

• 2:08:10Lex Fridman?

  Well, I think of it the same way.

• 2:08:11Andrew D. Huberman?

  I was raised thinking that if you overdress a little bit, overdressed by American, certainly by American standards, you're overdressed for a podcast, but this is, but it's genuine. You're not doing it for any reason, except I have to assume, and I assumed at the time, that it was because you have a respect for your audience. You respect them enough to show up a certain way for them. It's for you also, but it's for them.

• 2:08:34Lex Fridman?

  Yeah.

• 2:08:34Andrew D. Huberman?

  And I think between that and your commitment to your friendships, the way that you talk about friendships and love and the way you hold up these higher ideals. I think at least as a consumer of your content and as your friend, I what I find is that in aggregate, you're communicating who you are. It doesn't have to be one quote or something. And I think that, you know, we were sort of obsessed by like the one Einstein quote or the one line of of poetry or something. But it's the I think you so embody the way that and Joe as well. It's about how you live your life and how you show up as a collection of things and said and done.

• 2:09:14Lex Fridman?

  Yeah, that's fascinating. So the aggregate is is the goal. The the tricky thing, and Jordan Peterson talks about this because he's under attack way more than you and I will ever be. But

• 2:09:26Andrew D. Huberman?

  For now.

• 2:09:27Lex Fridman?

  For now, right? This is very true for now. That the people who attack on the internet, this is one of the problems with Twitter, is they don't consider the aggregate. They they take a single statements. And so one of the defense mechanisms, again, why Joe's been an inspiration, is that when you in aggregate are a good person, a lot of people will know that. And so that makes you much more immune to the attacks of people that bring out an individual statement. There might be a misstatement of some kind, or doesn't express who you are.

• 2:10:06Lex Fridman?

  And so that I like that idea is the aggregate and the the power of the podcast is you have hundreds of hours out there and being yourself and people get to know who you are. And once they do, and you and you post pictures of screaming Roombas as you kick them, they will understand that you don't mean well. By the way, as a side comment, I don't know if I want to release this because it's not just the Roombas.

• 2:10:36Andrew D. Huberman?

  You have a whole dungeon of robots.

• 2:10:38Lex Fridman?

  Okay, so this is a, this is a problem. This, the Boston Dynamics came up against this problem, but let me just, let me work this out, like workshop this out with you. And maybe, because we'll post this, people will let me know.

• 2:10:55Lex Fridman?

  So there's legged robots, you know, they look like a dog. They have a very, I'm trying to create a very real, uh, human robot connection. But like, they're also incredible because you can throw them like off of a building and it'll land fine. And this is beautiful.

• 2:11:12Andrew D. Huberman?

  That's amazing. I've seen the Instagram videos of like cats getting, jumping off of like fifth story buildings and then walking away. No one should throw their cat out of the window.

• 2:11:21Lex Fridman?

  This is the problem I'm experiencing, or certainly kicking the robots. It's really fascinating how they recover from those kicks. But like, just seeing myself do it and also seeing others do it, it just does not look good. And I don't know what to do with that. Cause I, it's such a-

• 2:11:36Andrew D. Huberman?

  I'll do it.

• 2:11:39Andrew D. Huberman?

  I, see, but you don't, I, you, cause you-

• 2:11:42Lex Fridman?

  Robot, no, I'm kidding. Now, now I'm, you know what's interesting?

• 2:11:45Andrew D. Huberman?

  Yeah.

• 2:11:46Lex Fridman?

  Before today's conversation, I probably could do it. And now I think, I'm thinking about robots, bills of rights and things. I'm actually, and not, not for any, not to satisfy you or to satisfy anything, except that if I, if they have some sentient aspect to their being, then I would loathe to kick. I don't think we'd be able to kick it. You might be able to kick it the first time, but not the second. This, this is the problem of experience. One of the cool things is, uh, one of the robots I'm, I'm working with, you can pick it up by one leg and it's dangling. You can throw it in any kind of way and it'll land correctly. So it's really-

• 2:12:24Andrew D. Huberman?

  I have a friend who had a cat like that.

• 2:12:27Lex Fridman?

  Oh, man, we look forward to the letters from the cat.

• 2:12:30Andrew D. Huberman?

  Oh, no, I'm not suggesting anyone did that, but he had this cat and the cat, he would just, you know, throw it onto the bed from across the room and then it would run back for more somehow. They had, that was the nature of the relationship. I think most, no one should do that to an animal, but this cat seemed to, you know, return for it for whatever reason.

• 2:12:48Lex Fridman?

  The robot is a robot. It's fascinating to me how hard it is for me to do that. So it's unfortunate, but I don't think I can do that to a robot. Like I, I struggle with that. So for me to be able to do that with a robot, I have to almost get like into the state that I imagine like doctors get into when they're doing surgery. Like I have to start, I have to do what robotics colleagues of mine do, which is like start seeing it as an object.

• 2:13:15Andrew D. Huberman?

  Dissociate.

• 2:13:15Lex Fridman?

  Like dissociate. So it was just fascinating that I have to do that in order to do that with a robot. I just wanted to take that little bit of a tangent.

• 2:13:23Andrew D. Huberman?

  No, I think it's an important thing. I mean, I am not, I'm not shy about the fact that for many years I've worked on experimental animals and that's been a very challenging aspect to being a biologist. Mostly mice, but in the past, no longer, thank goodness, because I just don't like doing it. Larger animals as well. And now I work on humans, which I can give consent, verbal consent. So I think that it's extremely important to have an understanding of what the guidelines are and where one's own boundaries are around this. It's, it's, it's not just an important question. It might be the most important question before any work can progress.

• 2:14:02Lex Fridman?

  So you, you asked me about friendship. I know you have a lot of thoughts about friendship. What do you think is the value of friendship in life?

• 2:14:10Andrew D. Huberman?

  Well, for me personally, just because of my life, my life trajectory and arc, friendship and I should say I do have some female friends that are just friends, they're completely platonic relationships, but it's been mostly male friendship to me has been.

• 2:14:29Lex Fridman?

  It's been all male friendships for me, actually.

• 2:14:31Andrew D. Huberman?

  Interesting. Yeah. It's been an absolute lifeline. They are my family. I have a biological family and I have great respect and love for them and appreciation for them, but it, it provide, it's provided me the.

• 2:14:47Andrew D. Huberman?

  I wouldn't even say confidence, because there's always an anxiety in taking any good risk or any risk worth taking. It's given me the sense that I should go for certain things and try certain things to take risks, to weather that anxiety. And I, I don't consider myself a particularly competitive person, but I would sooner die than disappoint or let down one of my friends. I can think of nothing worse, actually, than disappointing one of my, my friends. Everything else is secondary to me.

• 2:15:21Lex Fridman?

  What disappointment?

• 2:15:23Andrew D. Huberman?

  Disappointing meaning not, I mean, certainly I strive always to show up as best I can for the friendship. And that can be in small ways. That can mean, you know, making sure the phone is away. Sometimes it's about, um, yeah, I'm terrible with punctuality because I'm an academic. And so I just get lost in time and I don't mean anything by it. But striving to, to listen, to, to enjoy good times and to make time. You know, it kind of goes back to this first variable we talked about, to make sure that I spend time and to get time in person and check in. And it's, I think there's so many ways in which friendship is vital to me. It's, it's actually to me what makes life worth living.

• 2:16:04Lex Fridman?

  Yeah. Well, there's a, I am surprised like with the high school friends, how we don't actually talk that often these days in terms of time. But every time we see each other, it's immediately right back to where we started. So I, you know, I struggle with that, how much time you really allocate to, um, for the, for the friendship to be deeply meaningful, because they're just, they're always there with me, even if we don't talk often. So there's a kind of loyalty. I, I think, uh, maybe it's a different style, but I think, um, much more, to me, friendship is being there in the hard times. I think like I I'm much more reliable when you're going through shit than than like

• 2:16:47Andrew D. Huberman?

  You're pretty reliable anyway.

• 2:16:49Lex Fridman?

  No, but if like you're if you're like like a wedding or something like that or like, um, I don't know. Like you want an award of some kind like, yeah, I'll congratulate the the shit out of you, but like that's not. And I'll be there, but that's not as important to me as being there when like nobody else is like just being there when shit is gets shit hits the fan or something stuff where the world turns their back on you, all those kinds of things. That to me, that's where friendship is meaningful.

• 2:17:19Andrew D. Huberman?

  Well, I know that to be true about you, and that's a felt thing and a real thing with you. Let me ask you one more thing about that, actually, because I'm not a practitioner of jujitsu. I know you are, Joe is, but years ago I read a book that I really enjoyed, which is Sam Sheridan's book, A Fighter's Heart. He talks about all these different forms of martial arts and um, and maybe it was in the book, maybe it was in an interview, but he said that, you know, fighting or being in physical battle with somebody, jujitsu, boxing, or some other form of physical, direct physical contact between two individuals creates this bond unlike any other. Because he said it's it's like a one night stand, you're sharing bodily fluids with somebody that you barely know. And I, you know, and I chuckled about it because it's it's kind of funny and it kind of tongue in cheek.

• 2:18:04Andrew D. Huberman?

  But at the same time, I think uh, this is a fundamental way in which um, members of a species bond is through physical contact. And certainly there are other forms, there's cuddling and there's hand holding and there's um, and there's sexual intercourse and there's all sorts of things.

• 2:18:20Lex Fridman?

  What's cuddling? I haven't heard of it.

• 2:18:22Andrew D. Huberman?

  I heard this recently, I didn't know this term, but there's a term, um, they've turned the noun cupcake into a verb. Cupcaking, it turns out, I just learned about this, cupcaking is when you spend time just cuddling. I didn't know about this, you heard it here first, although I heard it first just the other day, cupcaking is actually a

• 2:18:40Lex Fridman?

  Cuddling is everything, it's not just like, is it in bed or is that on the couch, like what's cuddling? I need to look up what cuddling is.

• 2:18:46Andrew D. Huberman?

  We need to look at this up and we need to define the variables. I think it definitely has to do with physical contact, I I'm told, but um, but in terms of Battle, competition, you know, and the Sheridan quote, I'm just curious. So do you get close or feel a bond with people that, for instance, you've rolled jiu jitsu with? Or even though you don't know anything else about them, is he, was he right about this?

• 2:19:15Lex Fridman?

  Yeah, I mean, on many levels, he also has the book, What A Fighter's Mind.

• 2:19:19Andrew D. Huberman?

  Yeah, that was the second one. He's, he's actually an excellent writer. What's interesting about him, just briefly about Sheridan, I don't know him, but I did a little bit of research. He, he went to Harvard, he was an art major at Harvard. He claims all he did was smoke cigarettes and do art. I don't know if his art was any good. And, and I think his father was in the SEAL teams. And then when he got out of Harvard, graduated, he took off around the world, learning all the forms of martial arts. And was early to the kind of ultimate fighting, kind of mixed martial arts and things. Great, great book.

• 2:19:50Lex Fridman?

  Yeah, it's, it's amazing. I don't actually remember it, but I read it and I remember thinking there was an amazing encapsulation of what makes fighting the like, the art, like what makes it compelling. I would say that there's so many ways that jiu jitsu, grappling, wrestling, combat sports in general, is like one of the most intimate things you could do. I don't know if I would describe it in terms of bodily liquids and all those kinds of things.

• 2:20:17Andrew D. Huberman?

  I think he was more or less joking, but.

• 2:20:20Lex Fridman?

  I think there's a few ways that it does that. So one, because you're so vulnerable.

• 2:20:31Lex Fridman?

  So that the honesty of stepping on the mat. And often all of us have ego, thinking we're better than we are at this particular art. And then the honesty of being submitted or being worse than you thought you are. And just sitting with that knowledge, that kind of honesty, we don't get to experience it in most of daily life. We can continue living somewhat of an illusion of our conceptions of ourselves. Cause people are not going to hit us with the reality. The mat speaks only the truth, that the reality just hits you. And that vulnerability is the same as like the loss of a loved one. It's the loss of a reality that you knew before.

• 2:21:16Lex Fridman?

  You now have to deal with this new reality. And when you're sitting there in that vulnerability, and there's these other people that are also sitting in that vulnerability, you get to really connect like, fuck. Like, I'm not as special as I thought I was. And life is like, not, you know, life is harsher than I thought I was. And we're just sitting there with that reality. Some of us can put words to them, some we can't. So I think that definitely is a thing that leads to intimacy.

• 2:21:44Lex Fridman?

  The other thing is, is the human contact. There is something about, I mean, like a big hug. Like during COVID, very few people hugged me and I hugged them. And I always felt good when they did. Like, we're all tested, and especially now we're vaccinated. But there's still people, this is true of San Francisco, this is true in Boston, that wanna keep not only six feet away, but stay at home and never touch you. That, that was, that loss of basic humanity is the opposite of what I feel in jiu-jitsu, where it was like, that, that contact where you're like, I don't give a shit about whatever rules we're supposed to have in society,

• 2:22:27Lex Fridman?

  where you're not, you have to keep a distance and all that kind of stuff. Just the hug, like, that, the intimacy of a hug, that's like a good bear hug, and you're like, just controlling another person. And also, there is some kind of love communicating through just trying to break each other's arms. I don't, I don't exactly understand why violence is the, such a close neighbor to love, but it is, like-

• 2:22:52Andrew D. Huberman?

  Well, in, you know, in the hypothalamus, the neurons that control sexual behavior, but also non-sexual contact, are not just nearby the neurons that control aggression and fighting. They are salt and pepper with those neurons.

• 2:23:10Andrew D. Huberman?

  It's a very interesting, and, you know, it almost sounds kind of risque and controversial and stuff. There's, I'm not anthropomorphizing about what this means, but in the brain, those structures are interdigitated. They, they, you can't, you can't separate them, except at a very fine level. And here, you're, the way you describe it is the same, as a real thing.

• 2:23:29Lex Fridman?

  I, I do wanna make an interesting comment. Again, these are things that could be taken out of context, but-

• 2:23:38Lex Fridman?

  You know, I, one of the amazing things about jiu jitsu is both guys and girls train it. And I was surprised, so like, I'm a big fan of yoga pants.

• 2:23:49Lex Fridman?

  You know, at the gym kind of thing. It reveals the beauty of the female form. But the, the thing is like, girls are, you know, dressed in skin tight clothes in jiu jitsu often. And I found myself like not at all thinking like that at all with, when training with girls. Well, the context is very non-sexual. But that, I was surprised to learn that. Like I, when I first started jiu jitsu, I thought, wouldn't that be kind of weird to train with the opposites that like, in something so intimate? Boys and girls, men and women, they, they roll jiu jitsu? Together, completely. Interesting. And the, the only times girls kind of try to stay away from guys, I mean, there's two contexts. Of course, there's always going to be creeps in this world. So everyone knows who, you know, who kind of to stay away from. And the other is like, there's a size disparity.

• 2:24:34Lex Fridman?

  So girls will often try to roll with people a little bit closer weight wise. But no, they're, that's one of the things that are empowering to women. That's, that's what they fall in love with when they start doing jiu jitsu is I, I can, first of all, they gain an awareness and a pride over their body, which is great. And then second, they get, especially later on, start submitting big dudes, like these like, uh, uh, bros that come in who are all shredded and like muscular. And they get to technique to, uh, exercise dominance over them. And that's a powerful feeling. To be, you've seen women force a, a larger guy to tap or even choke him out?

• 2:25:12Lex Fridman?

  Well, I was, uh, I was deadlifting, uh, uh, uh, for, oh, boy, I think it's 495. So I was really into powerlifting when I started jiu jitsu. And I remember being submitted by, you know, I thought I walked in feeling like I'm going to be, if not the greatest fighter ever, at least top three. And so as a white belt, you roll in like all happy. And then you realize that as long as you're not applying too much force, that you're having, I remember being submitted many times by like 130, 120 pound girls. At, uh, Balance Studios in Philadelphia, had a lot of incredible female jiu jitsu players. And that's really humbling too, the technique.

• 2:25:56Lex Fridman?

  Can overpower in combat pure strength. And that that's the other thing that there is something about combat that's primal. Like that there it just feels it feels like um. We were born to do this like that.

• 2:26:16Andrew D. Huberman?

  Well, we have circuits in our brain that are dedicated to this kind of interaction. There's no there's no question.

• 2:26:23Lex Fridman?

  And like that's what it felt like. It wasn't that I'm learning a new skill. It was like somehow I am remembering echoes of something I've learned in the past.

• 2:26:34Andrew D. Huberman?

  It's like hitting puberty. A child before puberty has no concept of boys and girls having this attraction, regardless of whether or not they're attracted to boys or girls. It doesn't matter. At some point, most people, not all, but certainly, but most people, when they hit puberty, suddenly people appear differently. And certain people take on a romantic or sexual interest for the very first time.

• 2:26:57Lex Fridman?

  Yeah.

• 2:26:57Andrew D. Huberman?

  And so it's like it's revealing a circuitry in the brain. It's not like they learn that it's innate. And I think when I hear the way you describe jujitsu and and rolling jujitsu, it reminds me a little bit Joe was telling me recently about the first time he went hunting. And he felt like it revealed a circuit that was that was in him all along, but he hadn't experienced before.

• 2:27:20Lex Fridman?

  Yeah, that's that's definitely there. And and of course, there's the physical activity. One of the interesting things about jujitsu is it's one of the really strenuous exercises that you can do late into your adult life, like into your 50s, 60s, 70s, 80s. I've when I when I came up, there's a few people in their 80s that were training. And as long as you're smart, as long as you practice techniques and pick your partners correctly, you can do that kind of art. It's late into life and you see you're getting exercise. There's not many activities I find that are amenable to that. So because it's such a thinking game, the the jujitsu in particular is an art where technique pays off a lot.

• 2:28:03Lex Fridman?

  So you can still maintain, first of all, remain injury free if you use good technique. And also through good technique, be able to go, you know, be active with people that are much, much younger. And so that was to me, that and running are the two activities you can kind of do late in life. Because. To me, a healthy life is has exercises as the piece of the puzzle.

• 2:28:29Andrew D. Huberman?

  No, absolutely. And I'm glad that we're on the physical component because I know that there's for you, you've talked before about the crossover between the physical and the intellectual and the mental and are you still running at ridiculous hours of the night for ridiculously long?

• 2:28:49Lex Fridman?

  Yeah, so I'm definitely I've been running late at night here in Austin. People tell me the area we're in now, people say is a dangerous area, which I find laughable coming from the bigger cities. No, I run late at night. There's something.

• 2:29:05Andrew D. Huberman?

  If you see a guy running through Austin at 2am in a suit and tie, it's probably.

• 2:29:12Lex Fridman?

  Well, yeah, I mean, I do think about that because I get recognized more and more in Austin. I worry that not really that I get recognized late at night, you know, but there's something about the night that brings out those deep philosophical thoughts and self-reflection that I really enjoy. But recently I started getting back to the grind. So I'm going to be competing or hoping to be compete in September and October.

• 2:29:39Andrew D. Huberman?

  And jujitsu.

• 2:29:40Lex Fridman?

  And jujitsu, yeah, to get back to competition. And so that requires getting back into great cardio shape. I've been getting running as part of my daily routine.

• 2:29:52Andrew D. Huberman?

  Got it. Well, I always know I can reach you regardless of time zone in the middle of the night, wherever that happens.

• 2:29:59Lex Fridman?

  Well, part of that has to be just being single and being a programmer. Those two things just don't work well in terms of a steady sleep schedule.

• 2:30:08Andrew D. Huberman?

  It's not banker's hours kind of work, nine to five. I want to, you mentioned single. I want to ask you a little bit about the other form of relationship, which is romantic love. So your parents are still married?

• 2:30:22Lex Fridman?

  Still married, still happily married?

• 2:30:24Andrew D. Huberman?

  That's impressive.

• 2:30:24Lex Fridman?

  Yeah.

• 2:30:25Andrew D. Huberman?

  A rare thing nowadays.

• 2:30:26Lex Fridman?

  Yeah.

• 2:30:27Andrew D. Huberman?

  So you grew up with that example?

• 2:30:28Lex Fridman?

  Yeah, I guess that's a powerful thing, right? If there's an example that I think can work.

• 2:30:34Andrew D. Huberman?

  Yeah, I didn't have that in my own family, but when you, when I see it, it's, it's inspiring and it's, and it's beautiful. The fact that they have that and that was the norm for you, I think is, is really wonderful.

• 2:30:46Lex Fridman?

  It was, in the case of my parents, it was interesting to watch because. There's obviously tension, like there'll be times where they fought and all those kinds of things. They uh, they obviously get frustrated with each other and they like, but they find mechanisms how to communicate that to each other, like to make fun of each other a little bit, like to tease, to get some of that frustration out and then ultimately to reunite and to find their joyful moments and be that the energy. I think it's clear because I got together in their, I think, early twenties, like very, very young. I think you grow together as people. Yeah, you're still in the critical period of brain plasticity.

• 2:31:27Lex Fridman?

  And also, I mean, it's just like divorce was so frowned upon that you stick it out. And I think a lot of couples, especially from that time in the Soviet Union, that's probably applies to a lot of cultures, you stick it out and you put in the work, you learn how to put in the work. And once you do, you start to get to some of those rewarding aspects of being like through time, sharing so many moments together. Yeah, that, that's definitely something that um, that was an inspiration to me, but maybe that's where I have, so I have a similar kind of longing to have a lifelong partner, like that have that kind of view where same with friendship, lifelong friendship is the most meaningful

• 2:32:09Lex Fridman?

  kind, that there's something with that time of sharing all that time together, like till death do us part is a powerful thing, not by force, not because the religion said it or the government said it or your culture said it, but because you want to. Do you want children? Definitely, yeah. Definitely want children. It's, it's How many Roombas do you have? Oh, oh, I thought You should No, no. Human children. No, human, human children. Because I already have the children. Exactly. Well, I was saying you probably need at least as many uh, human children as you do Roombas, big family, small family.

• 2:32:42Lex Fridman?

  So In your mind's eyes, there are big, there are a bunch of, bunch of old Fridman running around? So I'll tell you, like realistically, I can explain exactly my thinking, and this is similar to the robotics work is if I'm like purely logical right now, my answer would be I don't want kids because

• 2:33:04Lex Fridman?

  I just don't have enough time. I have so much going on. But when I'm using the same kind of vision I use for the robots is I know my life would be transformed with the first. Like, I know I would love being a father. And so the question of how many I that that's on the other side of that hill. It it could be some ridiculous number. So I just know that.

• 2:33:26Andrew D. Huberman?

  I I have a feeling and I could be I I don't have a crystal ball. But I don't know, I I see an upwards of of certainly three or more come comes to mind.

• 2:33:37Lex Fridman?

  So so much of that has to do with the partner you're with too. So like that, that's such an open question, especially in this society of what the right partnership is. Cause I'm I'm I'm deeply empathetic. I want to see like to me. What I look for in a relationship is for me to be really excited about the passions of another person. Like whatever they're into, it doesn't have to be a career success, any kind of success, just to be excited for them. And for them to be excited for me and they share in that excitement and build and build and build. But there's also practical aspects of like, what kind of shit do you enjoy doing together? And I think family is a real serious undertaking.

• 2:34:22Andrew D. Huberman?

  Oh, it's it. It certainly is. I mean, I think that I have a friend who said it, I think, best, which is that.

• 2:34:30Andrew D. Huberman?

  You first have, he's in a very successful relationship and and has a family. And he said, you first have to define the role and then you have to cast the right person for the role.

• 2:34:41Lex Fridman?

  Well, yeah, there there's some deep aspect to that, but there's also an aspect to which you're not smart enough. From this side of it to define the right to to define the role. And there's part of it that has to be a leap that you have to take. And I I see.

• 2:34:59Lex Fridman?

  I see having kids that way. You just, you just have to go with it and figure it out also. As long as there's love there, like what the hell is life for even? So I've, uh, there's so many incredibly successful people that I know that I've gotten to know that all have kids. And the presence of kids, for the most part, has only been something that energized them, something that gave them meaning, something that made them the best versions themselves, like made them more productive, not less, which is fascinating to me.

• 2:35:33Andrew D. Huberman?

  It is fascinating. I mean, you can imagine if the way that you felt about Homer, the way that I feel and felt about Costello is, is at all a, a glimpse of what that must be like, then.

• 2:35:44Lex Fridman?

  Exactly.

• 2:35:45Andrew D. Huberman?

  You know?

• 2:35:45Lex Fridman?

  The, the downside, the thing I worry more about is, uh, the, uh, the partner side of that. I've seen, uh, the kids are almost universally a source of increased productivity and joy and happiness. Uh, like, yeah, they're a pain in the ass. Yeah, it's complicated. Yeah. So, so on and so forth. People like to complain about kids. But when you actually look past that little shallow layer of complaint, kids are great. The source of pain for a lot of people is the, if when their relationship doesn't work. And so I'm very kind of concerned about, like, you know, dating is very difficult. And I'm a complicated person. And so it's, it's been very difficult to find, um,

• 2:36:30Lex Fridman?

  to find the right kind of person. But that, that statement doesn't even make sense because I'm not on dating apps. I don't see people. You're like the first person I saw in a while. It's like you, Michael Malice and like Joe. So like, um, I don't think I've seen, uh, like, uh,

• 2:36:48Lex Fridman?

  a female, what is it? Uh, an element of the female species in quite, in quite a while. So I think you have to put yourself out there. What is it? Uh, Daniel Johnston says, true love will find you, uh, but only if you're looking. So there's some element of really taking the leap and putting yourself out there in kind of different situations. Um, and I don't know how to do that when you're behind a computer all the time.

• 2:37:10Andrew D. Huberman?

  Well, you're a, uh, you're a builder and you're a problem solver. And, um, uh, you're, you find solutions and, uh, I'm confident this solution is, uh, the solution is out there and.

• 2:37:24Lex Fridman?

  I think you're implying that I'm going to build the girlfriend, which, uh,

• 2:37:28Lex Fridman?

  I think.

• 2:37:28Andrew D. Huberman?

  Or that you or well, and maybe we shouldn't separate this friendship. The notion of friendship and community and the if we go back to this concept of the aggregate. You know, maybe you'll meet this woman through through a friend or maybe or something of that sort.

• 2:37:43Lex Fridman?

  So one of the things, I don't know if you if you feel the same way. I definitely one of those people that just falls in love and that's it.

• 2:37:52Andrew D. Huberman?

  Yeah, I can't say I'm like that. With Costello, it was instantaneous.

• 2:37:56Lex Fridman?

  Yeah.

• 2:37:57Andrew D. Huberman?

  It really was. I mean, I know it's not it's not romantic love, but it was instantaneous. No, I but that's me, you know, and I think that if you know, you know, because that that's a that's a good thing that you have that.

• 2:38:08Lex Fridman?

  Well, it's a I'm very careful with that. Because you don't want to fall in love with the wrong person. So I try to be very kind of careful with I I've noticed this because I fall in love with everything. This mug, everything I fall in love with things in this world. So like you have to be really careful because a girl comes up to you and says she loves Dostoevsky. That doesn't necessarily mean you to marry her tonight.

• 2:38:36Andrew D. Huberman?

  Exactly, yes, and I like the way you said that out loud so that you heard it. It doesn't mean you need to marry her tonight.

• 2:38:42Lex Fridman?

  Exactly, right. But I mean, but people people are amazing and people are beautiful and that's. So I I'm fully embrace that, but I also have to be careful with with relationships. And at the same time, like I mentioned to you offline, I don't. There's something about me that appreciates swinging for the fences and not dating. Like doing serial dating or dating around.

• 2:39:05Andrew D. Huberman?

  Yeah, you're a one guy, one girl kind of guy.

• 2:39:07Lex Fridman?

  Yeah.

• 2:39:08Andrew D. Huberman?

  He said that.

• 2:39:08Lex Fridman?

  And it's it's tricky because you want you want to be careful with that kind of stuff. Especially now there's a growing platform that have a ridiculous amount of female interest of of a certain kind, but I'm looking for deep connection. And and I'm looking by sitting home alone. And every once in a while, talking to Stanford professors.

• 2:39:31Andrew D. Huberman?

  Perfect solution. Perfect solution.

• 2:39:33Lex Fridman?

  It's gonna work out great.

• 2:39:33Andrew D. Huberman?

  It's well incorporated. It's part of, that constitutes machine learning of sorts.

• 2:39:39Lex Fridman?

  Yeah, of sorts.

• 2:39:41Andrew D. Huberman?

  I would do, you mentioned what has now become a quite extensive and expansive public platform, which is incredible. I mean, the number of people, first time I saw your podcast, I noticed the suit. I was like, he respects his audience, which was great. But I also thought, this is amazing. You know, people are showing up for science and engineering and technology information and those discussions and other sorts of discussions. Now, I do want to talk for a moment about the podcast. So my two questions about the podcast are, when you started it, did you have a plan? And regardless of what that answer is, do you, do you know where you're taking it? Or would you like to leave us? I do believe in an element of surprise is always fun. But what about the podcast?

• 2:40:26Andrew D. Huberman?

  Do you enjoy the podcast? I mean, your audience certainly includes me, really enjoys the podcast. It's incredible.

• 2:40:32Lex Fridman?

  So I love talking to people. And there's something about microphones that really bring out the best in people. Like, you don't get a chance to talk like this. If you and I were just hanging out, we would have a very different conversation in the amount of focus we allocate to each other. We would be having fun, talking about other stuff and doing other things. There would be a lot of distraction. There would be some phone use and all that kind of stuff. But here, we're 100% focused on each other and focused on the idea. And like, sometimes playing with ideas that we both don't know, like, the answer to, like, a question we don't know the answer to. We're both like fumbling with it, trying to figure out, trying to get some insights

• 2:41:17Lex Fridman?

  at something we haven't really figured out before and together arriving at that. I think that's magical. I don't know why we need microphones for that, but we somehow do.

• 2:41:25Andrew D. Huberman?

  It feels like doing science.

• 2:41:26Lex Fridman?

  It feels like doing science for me, definitely. That's exactly it. Then, and I'm really glad you said that because I don't actually often say this, but that's exactly what I felt like. I wanted to talk to friends and colleagues at MIT to do real science together. That's how I felt about it. Like, to really talk to problems that are actually interesting.

• 2:41:53Lex Fridman?

  As opposed to like incremental work that we're currently working for for a particular conference. So really asking questions like, what are we doing? Like, where's this headed to? Like, what are the big, is this really going to help us solve, in the case of AI, solve intelligence? Like, is this even working on intelligence? There's a, there's a certain sense, which is why I initially called it artificial intelligence, is like, most of us are not working on artificial intelligence. You're, you're working on some very specific problem and a set of techniques. At the time, it's machine learning to solve this particular problem.

• 2:42:32Lex Fridman?

  This is not going to take us to a system that is anywhere close to the generalizability of the human mind, like the kind of stuff the human mind can do in terms of memory, in terms of cognition, in terms of reasoning, common sense reasoning. This is, doesn't seem to take us there. See, the initial impulse was, can I talk to these folks, do science together through conversation? And I also thought that there was not enough. Now, I didn't think there was enough good conversations with world-class minds that I got to meet, and not the ones with a book. Or, this was the thing, oftentimes you go on this tour when you have a book, but there's a lot of minds that don't write books.

• 2:43:16Lex Fridman?

  And the books constrain the conversation too, because then you're talking about this thing, this book. But there's, I've, I've noticed that with people that haven't written a book, who are brilliant, we get to talk about ideas in a new way. We both haven't actually, when we raise a question, we don't know the answer to it when the question is raised, and we try to arrive there. Like, I don't know, I remember asking questions of world-class researchers in deep learning, of why do neural networks work as well as they do? That question is often loosely asked, but like, when you have microphones,

• 2:43:59Lex Fridman?

  and you have to think through it, and you have 30 minutes to an hour to think through it together, I think that's, that's science. I think that's really powerful. So that was, that was the one goal. The other one is,

• 2:44:13Lex Fridman?

  I again, don't usually talk about this, but

• 2:44:17Lex Fridman?

  there's some sense in which I wanted to have dangerous conversations.

• 2:44:22Lex Fridman?

  Part of the reasons I wanted to wear a suit is like, I wanted to be fearless. The reason I don't usually talk about it is because I feel like I'm not good at conversation. So it looks like it doesn't match the current skill level. But I wanted to have really

• 2:44:42Lex Fridman?

  dangerous conversations that I uniquely would be able to do.

• 2:44:48Lex Fridman?

  Not completely uniquely, but like, I'm a huge fan of Joe Rogan. And I had to ask myself, what conversations can I do that Joe Rogan can't? For me, I know I bring this up.

• 2:45:02Lex Fridman?

  But for me, that person I thought about at the time was Putin. Like, that's, that's why I bring him up. He's, he's, uh, just like with Costello. He's not just a person. He's also an idea to me for what I strive for, is to have those dangerous conversations. And the reason I'm uniquely qualified is both the Russian, but also there's the judo and the martial arts. There's a lot of elements that make me have a conversation he hasn't had before. And, um, and there's a few other people that I kept in mind, like Don Knuth. He's a computer scientist from Stanford that I thought is one of the most beautiful minds ever.

• 2:45:44Lex Fridman?

  And nobody really talked to him, like, really talked to him. He did a few lectures which people loved, but really just have a conversation with him. There's a few people like that. One of them passed away, John Conway, that I never got, we agreed to talk, but he died before we did. There's a few people like that, that I thought like, it's such a crime. To not hear those folks. And I have the unique ability to know how to purchase a microphone on Amazon and plug it into a device that records audio and then publish it, which seems relatively unique. Like, that's not easy in the scientific community, people knowing how to plug in a microphone.

• 2:46:26Andrew D. Huberman?

  No, they can build Faraday cages and two photon microscopes and bioengineer all sorts of things, but the idea that you could take ideas and export them into a structure or pseudo-structure that people would benefit from seems like a cosmic achievement to them.

• 2:46:44Lex Fridman?

  I don't know if it's a fear or just basically they haven't tried it, so they haven't learned the skill level.

• 2:46:50Andrew D. Huberman?

  I think they're not trained, I mean, we could riff on this for a while, but I think that, but it's important, and maybe we should, which is that it's, they're not trained to do it. They're trained to think in specific aims and specific hypotheses, and many of them don't care to, right? They don't, they became scientists because that's where they felt safe, and so why would they leave that haven of safety?

• 2:47:15Lex Fridman?

  Well, they also don't necessarily always see the value in it. It's, we're all together learning. You and I are learning the value of this. I think you're probably, you have an exceptionally successful and amazing podcast that you started just recently.

• 2:47:30Andrew D. Huberman?

  Thanks to your encouragement.

• 2:47:32Lex Fridman?

  Well, but there's, there's a raw skill there that, that's, you're definitely an inspiration to me in how you do the podcast, in the, in the level of excellence you reach. But I think you've discovered that that's also an impactful way to do science, that podcast. And I think a lot of scientists have not yet discovered that, that this is, if they apply the same kind of rigor as they do to academic publication, or to even conference presentations, and they do that rigor and effort to, to podcast, whatever that is, that could be a five-minute podcast, a two-hour podcast, it could be conversational, or it can be more like lecture-like, if they apply that effort, you have the potential to reach

• 2:48:16Lex Fridman?

  over time, tens of thousands, hundreds of thousands, millions of people. And that's, that's really, really powerful. But yeah, for, for me, giving a platform to a few of those folks, especially for me personally, so maybe you can speak to what fields. You're drawn to, but I thought computer scientists

• 2:48:41Lex Fridman?

  were especially bad at this. So there's brilliant computer scientists that I thought

• 2:48:48Lex Fridman?

  it would be amazing to explore their mind, explore their thinking. And so that I took that almost as an on as an effort. And at the same time, I had other guests in mind or people that connect to my own interests. So the wrestling, wrestling, music, football, both American football and soccer. I have a few particular people that I'm really interested in.

• 2:49:15Lex Fridman?

  Boval Sarsatia, the Satia brothers, even Khabib for wrestling, just to talk to them.

• 2:49:20Andrew D. Huberman?

  Oh, because you can, you guys can communicate.

• 2:49:23Lex Fridman?

  In Russian and in wrestling. Right. As wrestlers and as Russians. And so that that little, it's like an opportunity to explore a mind that that I'm able to bring to the world. And also, it, I feel like it makes me a better person. Just that being that vulnerable and exploring ideas together. I don't know, like good conversation. I don't know how often you have really good conversation with friends, but like podcasts are like that. And it's deeply moving.

• 2:49:57Andrew D. Huberman?

  It's the best, you know, and, and what, what you've brought through. I mean, when I saw you sit down with Penrose, you know, Nobel Prize winning physicists and these other folks. It's not just because he has a Nobel, it's what comes out of his mouth is incredible. And what you were able to

• 2:50:10Andrew D. Huberman?

  to hold in that conversation was so much better. Light years beyond what he had any other interviewer. I don't want to even call you an interviewer because it's really about conversation. Light years beyond what anyone else had been able to engage with him was, was such a beacon of what's possible. And I know that, I think that's what people are drawn to. And, and there's a certain intimacy that certainly if two people are friends as we are and they know each other, that there's more of that, but there's an intimacy in those kinds of private conversations that are made public. And

• 2:50:45Lex Fridman?

  Well, that's the, with you, you're probably starting to realize and Costello is like.

• 2:50:52Lex Fridman?

  Part of it, because you're authentic and you're putting yourself out there completely, people are almost not just consuming the words you're saying. They also enjoy watching you, Andrew, struggle with these ideas or try to communicate these ideas. They like the flaws. They like, they like a human being.

• 2:51:13Andrew D. Huberman?

  Oh, good. They like flaws? Well, that's good, because I got plenty of those.

• 2:51:16Lex Fridman?

  Well, they like the self-critical aspects, like where you're very careful, where you're very self-critical about your flaws. I mean, that, in that same way, it's interesting, I think, for people to watch me talk to Penrose, not just because Penrose is communicating ideas, but here is this, like, silly kid trying to explore ideas. Like, they know this kid. There's a human connection that is really powerful. Same, I think, with Putin, right? Like, it's not just a good interview with Putin. It's also here's this kid struggling to, uh, to talk with one of the most powerful, uh, and some would argue, dangerous people in the world. That, they love that. The authenticity that led up to that.

• 2:52:01Lex Fridman?

  Like, and in return, I get to connect everybody I run to in the street and all those kinds of things. There's a depth of connection there, almost within like a minute or two, that's unlike any other.

• 2:52:14Andrew D. Huberman?

  Yeah, there's an intimacy that you've formed with them.

• 2:52:16Lex Fridman?

  Yeah, we've been on this, like, journey together. And yeah, I have the same thing with Joe Rogan before I ever met him, right? Like, I was, because I was a fan of Joe for so many years. You have, there's something, there's a kind of friendship, as absurd as it might be to say, in podcasting, in listening to podcasts.

• 2:52:35Andrew D. Huberman?

  Yeah, maybe it, maybe it fills in a little bit of that, or solves a little bit of that loneliness that you're talking about.

• 2:52:41Lex Fridman?

  Until the robots are here.

• 2:52:44Andrew D. Huberman?

  I have just a couple more questions, but one of them is on behalf of your audience, which is I'm not going to ask you the meaning of the hedgehog, but I just want to know, does it have a name? And you don't have to tell us the name, but just does it have a name? Yes or no?

• 2:53:02Lex Fridman?

  Well, there's a, there's a name he likes to be referred to as. And then there's a private name in the privacy of our own company that we call each other. No, I'm not that insane. No, his name is Hegi.

• 2:53:17Lex Fridman?

  He's a hedgehog. I don't like stuffed animals. But his story is one of minimalism. So I gave away everything I own now three times in my life. By everything, I mean, almost everything. Kept jeans and shirt and a laptop. And recently, it's also been guitar, things like that.

• 2:53:41Lex Fridman?

  But he survived because he was always in the, at least in the first two times, was in the laptop bag and he just got lucky. And so I just like the perseverance of that. And I first saw him in the, the reason I got a stuffed animal and I don't have other stuffed animals is it was in a thrift store

• 2:54:03Lex Fridman?

  in this like giant pile of stuffed animals. And he jumped out at me because unlike all the rest of them, he has this intense, mean look about him. That he's just, he's upset at life, at the cruelty of life. And just especially in the contrast of the other stuffed animals, they have this dumb smile on their face. If you look at most stuffed animals, they have this dumb look on their face. They're just happy. It's like Pleasantville.

• 2:54:30Andrew D. Huberman?

  That's what we say in neuroscience. They have a smooth cortex, not, not many folds.

• 2:54:34Lex Fridman?

  Exactly. And this like Hegi like saw through all of it. He was like a Dostoevsky's man from underground. I mean, there's a sense that he saw the darkness of the world and persevered. So like, and there's also a famous Russian cartoon, Hedgehog in the Fog, that I grew up with, I connected with. There's people who know of that cartoon, you can see it on YouTube.

• 2:54:59Andrew D. Huberman?

  It's like Hedgehog in the Fog?

• 2:55:00Lex Fridman?

  Yeah.

• 2:55:03Lex Fridman?

  It's just as you would expect, especially from like early Soviet cartoons. It's a hedgehog, like sad.

• 2:55:11Lex Fridman?

  Walking through the fog, exploring loneliness and sadness. It's like, but it's beautiful. It's like a piece of art. People should, even if you don't speak Russian, you'll see, you'll understand.

• 2:55:21Andrew D. Huberman?

  Oh, it's, I, the moment you said that, I was gonna ask, so it's in Russian, but of course it's in Russian.

• 2:55:25Lex Fridman?

  It's in Russian, but it's more, there's very little speaking in it. It's almost, there's an interesting exploration of, of how you make sense of the world when you see it only vaguely through the fog. So he's trying to understand the world.

• 2:55:45Andrew D. Huberman?

  Here we have Mickey Mouse.

• 2:55:46Lex Fridman?

  Yeah.

• 2:55:47Andrew D. Huberman?

  We have Bugs Bunny.

• 2:55:48Lex Fridman?

  Yeah.

• 2:55:48Andrew D. Huberman?

  We have all these, you know, crazy animals and you have the hedgehog in the fog.

• 2:55:53Lex Fridman?

  So there's a, there's a certain period, and this is again, I don't know what it's to attribute it to, but it's really powerful, which there's a period in Soviet history, I think probably seventies and eighties, where like especially kids were treated very seriously. Like they were treated like they're able to deal with the, with the weightiness of life. And that was reflected in the cartoons.

• 2:56:21Lex Fridman?

  And there was a, it was allowed to have like, like really artistic content. Not like dumb cartoons that are trying to get you to be like smile and run around, but like create art, like stuff that, you know how like short cartoons or short films can win Oscars? Like that's what they're swinging for.

• 2:56:38Andrew D. Huberman?

  So what, what strikes me about this is a little bit how we were talking about the suit earlier. It's almost like they treat kids with respect.

• 2:56:45Lex Fridman?

  Yeah.

• 2:56:45Andrew D. Huberman?

  Like that they have, that they have an intelligence and they honor that intelligence.

• 2:56:49Lex Fridman?

  Yeah, they're really just adult in a small body. Like you want to protect them from the true cruelty of the world.

• 2:56:56Andrew D. Huberman?

  Sure.

• 2:56:56Lex Fridman?

  But in terms of their intellectual capacity or like philosophical capacity, they're right there with you. And so the cartoons reflected that, the art that they consumed, the education reflected that. So he represents that. And there's a

• 2:57:11Lex Fridman?

  There's a sense because he survives so long and because I don't like stuffed animals that it's like we've been through all of this together and it's the same sharing the moments together is the friendship and there's a sense in which, you know, if all the world turns on you and goes to hell, at least we got each other that, and he doesn't die because he's an inanimate object. So.

• 2:57:35Andrew D. Huberman?

  Until you animate him.

• 2:57:37Lex Fridman?

  Until you animate him and then I probably wouldn't want to know what he was thinking about this whole time. He's probably really into Taylor Swift or something like that. It's like that I wouldn't even want to know. Anyway.

• 2:57:48Andrew D. Huberman?

  Well, um, well, I now feel a connection to Hedgy, the hedgehog that I certainly didn't have before. And I think that encapsulates the kind of possibility of connection that is possible between human and other object and through, through robotics, certainly. There's a saying that I heard when I was a graduate student that I, that's just been ringing in my mind throughout this conversation in such a, I think, appropriate way, which is that Lex, you are in a minority of one. You are truly extraordinary in your ability to encapsulate so many aspects of science, engineering, public communication about so

• 2:58:32Andrew D. Huberman?

  many topics, martial arts, and the emotional depth that you bring to it and just the purposefulness. And I think if it's not clear to people, it absolutely should be stated, but I think it's abundantly clear that just the amount of time and thinking that you put into things is, uh, it is the ultimate mark of respect. So I'm just extraordinarily grateful for your friendship and for this conversation.

• 2:58:59Lex Fridman?

  I'm proud to be your friend and I just wish you showed me the same kind of respect by wearing a suit and make your father proud. Maybe next time.

• 2:59:07Andrew D. Huberman?

  Next time, indeed. Thanks so much, my friend.

• 2:59:10Lex Fridman?

  Thank you. Thank you, Andrew.
