Navigating Conflict, Finding Purpose & Maintaining Drive | Dr. Lex Fridman

My guest this episode is Lex Fridman, Ph. D., a Research Scientist at the Massachusetts Institute for Technology (MIT), an expert on artificial intelligence (AI) and robotics, and the host of the Lex Fridman Podcast. We discuss Lex’s recent trip to the heart of the Ukrainian-Russian War, geopolitics, perspectives on people living in war zones, the shared human experience, and how information is communicated and controlled. As an experienced podcaster and public educator, Dr. Fridman offers unique insights into the art of holding conversations that grow understanding, especially when they involve people with opposing viewpoints. We also discuss the peer-review process for scientific research publications and how social media and podcasts are evolving the way science and technology are communicated. We consider how to find and follow your life’s purpose, maintain ongoing motivation and implement support systems to build and sustain momentum. Our conversation also covers capitalism, masculinity, chess and cheating, Lex’s idea for an AI robotics start-up and a Q&A from audience questions solicited on social media. As one of the main inspirations for the Huberman Lab podcast, hosting Dr. Fridman for this special centennial episode was an honor and a pleasure! For the full show notes, visit hubermanlab.com.

  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, my guest is Dr. Lex Fridman. Dr. Lex Fridman is an expert in electrical and computer engineering, artificial intelligence, and robotics. He is also the host of the Lex Fridman Podcast, which initially started as a podcast focused on technology and science of various kinds, including computer science and physics, but rapidly evolved to include guests and other topics as a matter of focus, including sport. For instance, Dr. Lex Fridman is a black belt in Brazilian Jiu-Jitsu, and he's had numerous guests on who come from the fields of Brazilian Jiu-Jitsu, both from the coaching side and from the competitor side.

• 0:52Andrew D. Huberman?

  He also has shown an active interest in topics such as chess and essentially anything that involves intense activation and engagement of the mind and/or body. In fact, the Lex Fridman Podcast has evolved to take on very difficult topics such as mental health. He's had various psychiatrists and other guests on that relate to mental health and mental illness, as well as guests focused on geopolitics and some of the more controversial issues that face our times. He's had comedians, he's had scientists, he's had friends, he's had enemies on his podcast. Lex has a phenomenal, I would say, a one in an eight billion ability to find these

• 1:31Andrew D. Huberman?

  people, make them comfortable, and in that comfort, both try to understand them and to confront them and to push them so that we all learn. All of which is to say that Lex Fridman is no longer just an accomplished scientist. He certainly is that, but he has also become one of the more preeminent thought leaders on the planet. And if there's anything that really captures the essence of Lex Fridman, it's his love of learning, his desire to share with us the human experience, and to broaden that experience so that we all may benefit. In many ways, our discussion during today's episode captures the many facets of Lex Fridman, although no conversation, of course, could capture them all. We sit down to the conversation just days after Lex returned from Ukraine, where he

• 2:15Andrew D. Huberman?

  deliberately placed himself into the tension of that environment in order to understand the geopolitics of the region and to understand exactly what was happening at the level of the ground and the people there. You may notice that he carries quite a lot of both emotion and knowledge and understanding, and yet in a very classic Lex Fridman way, you'll notice that he's able to zoom out of his own experience around any number of different topics and view them through a variety of lenses, so that, first of all, everyone feel included, but most of all, so that everyone learns something new, that is, to gain new perspective. Our discussion also ventures into the waters of social media and how that landscape is changing the way that science and technology are communicated.

• 3:00Andrew D. Huberman?

  We also get into the topics of motivation, drive, and purpose, both finding it and executing on that drive and purpose. I should mention that this is episode 100 of the Huberman Lab Podcast, and I would be remiss if I did not tell you that there would be no Huberman Lab Podcast were it not for Lex Fridman. I was a fan of the Lex Fridman Podcast long before I was ever invited on to the podcast as a guest, and after our first recording, Lex was the one that suggested that I start a podcast. He only gave me two pieces of advice. The first piece of advice was, start a podcast, and the second piece of advice was that I not just make it me blabbing into the microphone and staring at the camera. So I can safely say that I at least followed half of his advice, and that I am ever grateful

• 3:45Andrew D. Huberman?

  for Lex, both as a friend, a colleague in science, and now fellow podcaster, for making the suggestion that we start this podcast. I already mentioned a few of the topics covered on today's podcast, but I can assure you that there is far more to the person that many of us know as Lex Fridman. If you are somebody interested in artificial intelligence, engineering, or robotics, today's discussion is most certainly for you, and if you are not, but you are somebody who's interested in world politics, and more importantly, the human experience, both the individual and the collective human experience. Lex shares what can only be described as incredible insights into what he views as the human experience and what is optimal in order to derive from our time on this planet.

• 4:29Andrew D. Huberman?

  Before we begin, I'd like to emphasize that this podcast is separate from my teaching and research roles at Stanford. 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.

And now NFL Network is on the ESPN app. More football, more coverage, more ways to watch. Football's on, all season long, on ESPN and streaming on the ESPN app.

• 6:11Andrew D. Huberman?

  And now for my discussion with Dr. Lex Fridman. Welcome back.

• 6:16Lex Fridman?

  It's good to be back in a bedroom. This feels like a porn set. I apologize to open that way. I've never been in a porn set, so I should admit this.

• 6:25Andrew D. Huberman?

  Our studio is being renovated, so here we are for the monumental recording of episode 100.

• 6:31Lex Fridman?

  Episode 100.

• 6:32Andrew D. Huberman?

  Of the Huberman Lab Podcast, which was inspired by the Lex Fridman Podcast. Some people already know this story, but I'll repeat it again. For those that don't, there would not be a Huberman Lab Podcast were it not for Lex Fridman, because after recording as a guest on his podcast a few years ago, he made the suggestion that I start a podcast and he explained to me how it works. And he said, you should start a podcast, but just make sure that it's not you labbing the whole time, Andrew, and I only sort of followed the advice.

• 7:04Lex Fridman?

  Yeah, well, you surprised, surprised me, surprised the world that you're able to talk for hours and cite some of the best science going on and be able to give people advice without many interruptions or edits or any of that. I mean, that takes an incredible amount of skill that you're probably born with and some of it is developed. I mean, the whole science community is proud of you, man. Stanford is proud of you. So, yeah, it's a beautiful thing. It was really surprising because it's unclear how a scientist can do a great podcast that's not just shooting the shit about random stuff, but really is giving very structured, good advice that's boiling down the state of the art science into something that's actually useful for people. So that was impressive.

• 7:49Lex Fridman?

  It's like, holy shit, he actually pulled this off. And doing it every week on a different topic. That, I mean, you know, I'm usually positive, especially for people I love and support. But damn, I thought there's no way he's going to be able to pull this off week after week. And he's been only getting better and better and better. I had a whole rant on a recent podcast, I forget with who, of how awesome you are, with Rana El Kalubi. She's an emotion recognition person, AI person. And then she didn't know who you were. And I was like, What the hell do you mean? And I just wanted this whole rant of how awesome you are. It's hilarious.

• 8:29Andrew D. Huberman?

  Well, I'm very gratified to hear this. I'm a it's a little uncomfortable for me to hear. But listen, I'm just really happy if people are getting information that they like and can make actionable. And it was inspired by you. And look right back at you. I I've followed a number of your structural formats. A tire. I don't wear a tie. I'm constantly reminded about this by my father, who says what it saw my podcast. He was like, why don't you dress properly like your friend Lex? He literally said that. And it's a debate that goes back and forth. But nonetheless.

• 9:05Lex Fridman?

  How's it feel? Episode 100. How does it feel?

• 9:08Andrew D. Huberman?

  You know, I think.

• 9:08Lex Fridman?

  Can you imagine you're you're here? You're here after so many episodes and done so much. I mean, the number of hours is just insane. The amount of passion, the amount of work you put into this. What's it feel like?

• 9:22Andrew D. Huberman?

  It feels great. And it feels very much like the the horizon is still at the same distance in front of me. You know, every episode, I just try and get information there. And the process, we talked about on your podcast, we won't go into it, of collecting information, distilling it down to some simple notes, walking around, listening to music, trying to, you know, figure out what the motifs are. And then, as just like you, I don't use a teleprompter or anything like that. There's very minimal notes. So it feels great and I love it. And again, I'm just grateful to you for inspiring it. And I just want to keep going and do more of it. And I should say, I am also relieved that we're sitting here because you recently went

• 10:04Andrew D. Huberman?

  overseas to a very intense war zone, literally, to Ukraine. And the entire time that you were there, I was genuinely concerned. You know, the world's a unpredictable place in general, and we don't always get the only vote and what happens to us. So first of all, welcome back safely, one piece, one alive piece. And what was that like? I mean, at a broad level, at a specific level, what drew you there? What surprised you? And how do you think it changed you in coming back here?

• 10:43Lex Fridman?

  I think there's a lot to say, but first, it is really good to be back. One of the things that when you go to a difficult part of the world, or a part of the world that's going through something difficult, you really appreciate how great it is to be an American. Everything, the easy access to food, despite what people think, the stable, reliable rule of law, the lack of corruption in that you can trust that if you start a business or if you take on various pursuits in life, that there's not going to be at-scale manipulation of your efforts such that you can't succeed. So this kind of, you know, capitalism and it's,

• 11:26Lex Fridman?

  and it's, the ideal of capitalism is really still burning bright in this country and it really makes you appreciate those aspects. And also just the ability to have a home for generations, across generations. So you can have your grandfather live in, I don't know, Kentucky in a certain city and then his children live there and you live there and then it just continues on and on. That's the kind of thing you can have when you don't have war. Because war destroys entire communities. It destroys histories, generations, like life stories that stretch across the generations.

• 12:07Andrew D. Huberman?

  Yeah, I didn't even think about that until you said just now, but photographs, hard drives get destroyed or just abandoned, right? Libraries. I mean nowadays, things exist in the cloud, but there are still a lot of material goods that have, you know, are irreplaceable, right?

• 12:23Lex Fridman?

  Well, even, you know, in rural parts of the United States that don't exist in the cloud, right? A lot of people still, well, even in towns, they still love the physical photo album of your family. A lot of people still store their photographs of families and the VHS tapes and all that kind of stuff, yeah. But I think... There's so many things I've learned and really felt the lessons. One of which is, nobody gives a damn when your photos are gone and all that kind of stuff. Your house is gone. The thing, time and time again, I saw for people that lost everything is how happy they are.

• 13:05Lex Fridman?

  For the people, they love the friends, the family that are still alive. That's the only thing they talk about. That, in fact, they don't mention, actually, with much dramatic sort of vigor about the trauma of losing your home. They're just nonstop saying how lucky they are that person X, person Y is still here. And that makes you realize that when you lose everything, it's the, it makes you realize what really matters, which is the people in your life. I mean, a lot of people kind of realize that later in life, when you're facing mortality, when you're facing your death, or, you know, you get a cancer diagnosis, that kind of stuff.

• 13:45Lex Fridman?

  I think people here in America, in California with the fires, you can still lose your home. You realize like, nah, it doesn't really matter. It's a pain in the ass, but what matters is still the family, the people, and so on. I think the most intense thing, I talked to several hundred people, some of which is recorded, I've really been struggling to put that out because I have to edit it myself. And so it's, you're talking about thirty, forty hours of footage. Is it emotionally struggling? Yeah. Emotional struggle? It's extremely difficult. So I talked to a lot of politicians, the number two in the country, number three. I'll be back there to talk to the president, to do a three-hour conversation. Those are easy to edit.

• 14:29Lex Fridman?

  You know, they're, they're really heartfelt and thoughtful folks from different perspectives on the geopolitics of the war. But the ones that's really hard to edit is like grandmas that are like in the middle of nowhere. They lost everything, they still have hope, they still have love. And some of them have, some of them, many of them unfortunately have now hate in their heart. So in February, when Russia invaded Ukraine, this is the thing I realized about war. One of the most painful lessons is that war creates generational hate.

• 15:08Lex Fridman?

  You know, we sometimes think about war as a thing that kills people, kills civilians, kills soldiers, takes away lives, injures people, but we don't directly think about the secondary and tertiary effects of that, which last decades, which is anyone who's lost a father, or a mother, or a daughter, or a son, they now hate, not just the individual soldiers or the leaders that invaded their country, but the entirety of the people. So it's not that they hate Vladimir Putin, or hate the Russian military, they hate Russian people.

• 15:50Lex Fridman?

  So that tears the fabric of a thing that, for me, you know, my, half my family is from Ukraine, half of my family is from Russia, but there's a, I remember, the pain, the triumph of World War II still resonates through my entire family tree. And so you remember when the Russians and Ukrainians fought together against this Nazi invasion, you remember a lot of that. And now to see the fabric of this people's torn apart completely with hate is really, really difficult for me, just to realize that things will just never be the same on

• 16:31Lex Fridman?

  this particular cultural, historical aspect, but also, there's so many painful ways in which things will never be the same, which is we've seen that it's possible to have a major hot war in the 21st century. I think a lot of people are watching this, China is watching this, India is watching this, United States is watching this, and thinking, we can actually have a large-scale war. And I think the lessons learned from that might be the kind that lead to a major World War III in the 21st century. So like, one of the things I realized, watching the whole scene... Is that we don't know shit about what's gonna happen in the 21st century.

• 17:15Lex Fridman?

  And it might, we kind of have this intuition, like surely, there's not gonna be another war. Like we'll just coast. Yeah. Yeah. Yeah, pandemic. And back to normal. Back to normal. Whatever that is. But you have to remember, at the end of World War I, you know, as Woodrow Wilson called it, the war to end all wars, nobody, ironically, in a dark way, it was also the roaring twenties, when people believed this, there will never be another world war. And 20 years after that, the rise of Nazi Germany, a charismatic leader that captivated the minds of millions and built up a military that can take on the whole world. And so, it makes you realize that this is still possible.

• 18:01Lex Fridman?

  This is still possible. And then the tension, you see the media machine, the propaganda machine, that I've gotten to see every aspect of, it's still fueling that division between America and China, between Russia and India. And then Africa has a complicated thing that's trying to figure out who are they with, who are they against? And just this tension is building and building. And like, it makes you realize, like, we might, the thing that might shake human civilization may not be so far off. That's a realization you get to really feel.

• 18:44Lex Fridman?

  I mean, there's all kinds of other lessons, and one of which is propaganda. Is I got to, I get a lot of letters, emails, and some of them are full of really intense language, full of hate from every side. Toward? Me. Well, the hate is towards me as representing side X.

• 19:08Lex Fridman?

  And X stands as a variable for every side. So either I'm a Zelensky show, or I'm a Putin show, or I'm a NATO show, or I'm an America, uh, America show, American empire show, or I'm a Democrat or a Republican, because it's already been in this country politicized. I think there's a sense of Ukraine is this place that's full of corruption. Why are we sending money there? I think that's kind of the messaging on the Republican side, on the Democratic side. I'm not even keeping track of the actual messaging and the conspiracy theories and, and the narratives, but they are, the tension is there and I get to feel it directly.

• 19:53Lex Fridman?

  And what you get to really experience is there's a large number of narratives that all are extremely confident in themselves that they know the truth. People are convinced, first of all, that they're not being lied to. People in Russia think there's no propaganda. They think that, yes, yes, there's like state sponsored propaganda, but we're all smart enough to ignore the, the, uh, the sort of lame propaganda that's everywhere. They know that we can think on our own. We, we know the truth and everybody kind of speaks in this way. Everybody in the United States says, well, yes, there's mainstream media. They're full of messaging and propaganda, but we, we're smart. We can think on our own. Of course, we see through that.

• 20:38Lex Fridman?

  Everybody says this and then the conclusion of their thought is often hatred towards some group, whatever that group is. And the more you've lost, the more intense the, the feeling of hatred. It's a really difficult, um, field to walk through calmly and with an open mind and try to understand what's really going on.

• 21:02Andrew D. Huberman?

  It's super intense. Those are the only words that come to mind as I hear this. You mentioned something that it seems that hate generalizes. You know, it's against an entire group or an entire country. Why do you think it is that hate generalizes and that love may or may not generalize?

• 21:23Lex Fridman?

  I've had, so one of the, as you can imagine.

• 21:28Lex Fridman?

  The kind of question I asked is, do you have

• 21:32Lex Fridman?

  love or hate in your heart? It's a question I ask almost everybody. And then I would dig into this exact question that you're asking.

• 21:41Lex Fridman?

  I think some of the most beautiful things I've heard, which is people that are full of hate are able to self introspect about it. They they know they shouldn't feel it, but they can't help it. It's not, they know that ultimately the thing that helps them and helps everyone is to feel love for fellow man. But they're, they've, they can't help it. They know it's like a drug. They say like hate escalates. It's like a vicious spiral. You just can't help it. And the question I also asked is, do you think you'll ever be able to forgive Russia? And after much thought, almost

• 22:24Lex Fridman?

  it's it's split, but most people will say, no. I will never be able to forgive.

• 22:32Andrew D. Huberman?

  And because of the generalization you talked about earlier, that could even include all Russians. Not say means they mean all Russians.

• 22:37Lex Fridman?

  Because

• 22:40Lex Fridman?

  because

• 22:43Lex Fridman?

  if you do nothing that's as bad or worse than than than being part of the army that invades. So the the people that are just sitting there, the good Germans, the people that are just quietly going on with their lives. You're just as bad, if not worse, is their perspective.

• 23:04Andrew D. Huberman?

  Earlier, you said that going over to the Ukraine is now allowed you to realize just so many of the positives of being here in the United States. I have a good friend, we both know him, I won't name him by name, but we've communicated, the three of us from tier one special operations, he spent years doing deployments, really amazing individual. And I remember when the pandemic hit. He said on a text thread, you know, Americans aren't used to the government interfering with their plans. You know, around the world, many people are familiar with governments dramatically interfering with their plans. Sometimes even in a seemingly random way. Here, we were not braced for that.

• 23:48Andrew D. Huberman?

  There, I mean, you know, there, we get speeding tickets and there's, you know, lines to vote and things like that. But I think the pandemic was one of the first times, at least in my life that I can remember, where it really seemed like the government was impeding what people naturally wanted to do. And that was a shock for people here. And I have a, what might seem like a somewhat mundane question, but it's something that I saw on social media. A lot of people were asking me to ask you, and I was curious about too. What was a typical day like over there? Were you sleeping in a bed? Were you sleeping on the ground? Everyone seems to want to know, what were you eating? Were you eating once a day? Were you eating your steak? Or were you, were you in fairly deprived conditions over there?

• 24:31Andrew D. Huberman?

  I saw a couple photos that you posted with out of doors, in front of rubble, with a pith helmet on in one case, you know. What, what was that typical day like over there?

• 24:46Lex Fridman?

  So there's, there's two modes. One of them, I spent a lot of time in Kiev, which is much safer than, it may be obvious to state, but for people who don't know, it's in the middle of the country and it's much safer than the actual front, that the, where the battle is happening. So the, much, much safer than Kiev even is Lviv, which is the western part of the country. So the times I spent in Kiev were fundamentally different than the time I spent at the front. And I went to the Kherson region, which is where a lot of really heated battle was happening. There's several areas. So there's Kharkiv, it's in northeast of the country. And then there's Donbass region, which is east of the country.

• 25:29Lex Fridman?

  And then there's Kherson region, which, but I'm not good at geography. So is the southeast of the country. And that's where, at least when I was there, was a lot of really heated fighting happening. So when I was in the Kherson region, there's, you know, it's what you would imagine.

• 25:50Lex Fridman?

  The place I stayed in a hotel where all the lights have to stay off. So the entire town, all the lights are off. You have to kind of navigate through the darkness and then use your phone to shine and so on.

• 26:02Andrew D. Huberman?

  This is terrible for the circadian system.

• 26:04Lex Fridman?

  Yeah, that's exactly how it was this. How can I do this? Where's my element in the flood of greens? How can I function? No, uh, there's, uh, I think it was balanced by the deep appreciation of being alive.

• 26:18Andrew D. Huberman?

  Right now, I mean, this is the reason I asked. This is the reason I ask is, you know, we, we get used to all these creature comforts.

• 26:25Lex Fridman?

  Yes.

• 26:26Andrew D. Huberman?

  And, um, we don't need them, but we often come to depend on them in a way that makes us feel like we need them.

• 26:33Lex Fridman?

  Yeah, but very quickly, there's something about the intensity of life that you see in people's eyes because they've been living through war. That makes you forget all those creature comforts. And it's, it was actually, um, you know, I'm somebody who hates traveling and so on. I love the creature habits. I love, I love, um, the comfort of the ritual, right? But all of that was forgotten very quickly. Just the, the intensity of feeling, the intensity of love that people have for each other. That was, that was obvious. In terms of food, so there's a curfew. Uh, so depends on what part of the country, but usually you basically have to scammer home at like nine P M.

• 27:14Lex Fridman?

  So the hard curfew in a lot of places is 11 P M. night. But by then you like, you have to be home. So, uh, in some places it's 10. So you, at nine P M. you start going home, which for me was, was kind of wonderful also because I get to spend, um, I get to be, uh, forced to spend time alone and think for many hours. You know, wherever I'm staying, which, which is really nice in every, there's a calmness and the quietness to the whole thing. In terms of food, once a day, uh, just, uh, the food is incredibly cheap.

• 27:54Lex Fridman?

  And incredibly delicious. People are still, one of the things they can still take pride in is making the best possible food they can. So meat, but they do admire American meat. So the meat is not as great as it could be in that country. But I eat borscht every day, you know, all that kind of stuff, mostly meat. So spend the entire day, wake up in the morning with coffee, spend the entire day talking to people, which for me is very difficult because of the intensity of the stories, one after the other, after the other. We just talk to regular people, talk to soldiers, talk to politicians, all kinds of soldiers.

• 28:35Lex Fridman?

  I talked to people there who are doing rescue missions, so Americans. I hung out with Tim Kennedy.

• 28:43Andrew D. Huberman?

  Oh, yeah. The great Tim Kennedy.

• 28:46Lex Fridman?

  The great Tim Kennedy, who also, him and many others, revealed to me, one of the many reasons I'm proud to be an American is how trained and skilled and effective American soldiers are.

• 29:05Andrew D. Huberman?

  I guess for listeners of this podcast, maybe we should familiarize them with who Tim Kennedy is, because I realize that a number of them will know.

• 29:11Lex Fridman?

  How do you do that? How do you try to summarize a man?

• 29:14Andrew D. Huberman?

  Right. In, let's, we can be accurate but not exhaustive, as any good, good data are accurate but not exhaustive. Very skilled and accomplished MMA fighter, very skilled and accomplished, former special operations, American patriot and podcaster too, right? Does he have his own podcast?

• 29:35Lex Fridman?

  Maybe, maybe.

• 29:37Andrew D. Huberman?

  We know Andy Stumpf has his own podcast.

• 29:38Lex Fridman?

  Yes, it's an amazing podcast. Yeah, Andy's great.

• 29:41Andrew D. Huberman?

  Yeah. Clearing Hot Podcast with Andy Stumpf.

• 29:44Lex Fridman?

  But also, Tim Kennedy is like the embodiment of America into the, to the most beautiful and the most ridiculous degree. So he's like, would you imagine?

• 29:55Lex Fridman?

  What is it, Team America? That, like, I just imagine him like shirtless on a tank, rolling into enemy territory, just screaming at the top of his lungs. That's just his personality.

• 30:07Andrew D. Huberman?

  But not posturing, that's it. He actually does the work, as they say.

• 30:10Lex Fridman?

  So this is the thing, he really embodies that. Now, some of that is just his personality and humor. I'd like to sort of comment on the humor of things, not just with him. It's very, one other interesting thing I've learned. But also, when he's actually helping people, he's extremely good at what he does, which is building teams that rescue, that go into the most dangerous areas of Ukraine, dangerous areas anywhere else, and they get the job done. And, but one of the things I heard time and time again, which, which really interesting to me, that Ukrainian soldiers said that, you know, comparing Ukrainian, Russian, and American soldiers, American soldiers are the bravest.

• 30:53Lex Fridman?

  Which was very interesting for me to hear, given how high the morale is for the Ukrainian soldiers. But that just reveals that training enables you to be brave. So it's not just about how well-trained they are and so on, it's how intense and ferocious they are in the fighting. And that makes you realize, like, this is American Army, not just through the technology, especially the special, special force guys, they still, is one of the most effective and terrifying armies in the world. And I'm, listen, just for context, I'm somebody who is, for the most part, anti-war, a pacifist. But you get to see, you know, some of the realities of war kind of wake you up to what

• 31:37Lex Fridman?

  needs to get done to protect sovereignty, to protect some of the values, to protect civilians and homes and all that kind of stuff. Sometimes, you know, war has to happen. And I should also mention on the Russian side, because...

• 31:54Lex Fridman?

  Well, I haven't gotten to experience the Russian side yet. I do fully plan to travel to Russia. As I've told everybody, I was very upfront with everybody about this. I would like to hear the story of Russians. But I do know from the Ukrainian side, like the grandmas, I love grandmas. They told me stories that the Russians, really, the ones that entered their villages, they really, really believe they're saving Ukraine from Nazis, from Nazi occupation. So they feel that Ukraine is under control of Nazi organizations and they believe they're saving the country that's their brothers and sisters.

• 32:34Lex Fridman?

  So I think propaganda and I think truth is a very difficult thing to arrive in that war zone. I think in the 21st century, one of the things you realize that so much of war, even more so than in the past, is an information war. And people that just use Twitter for their source of information might be surprised to know how much misinformation there is on Twitter, like real narratives being sold. And so it's really hard to know who to believe. And through all of that, you have to try to keep an open mind

• 33:14Lex Fridman?

  and ultimately ignore the powerful and listen to actual citizens, actual people. That's the other maybe obvious lesson is that war is waged by powerful, rich people and it's the poor people that suffer. And that's just visible time and time again.

• 33:36Andrew D. Huberman?

  You mentioned the fact that people still enjoy food or the pleasure of cooking, or there's occasional humor, or maybe frequent humor. I know Jaco Willink has talked about this in Warfare and that all the elements of the human spirit and condition still emerge at various times. I find this amazing, and you and I have had conversations about this before, but the aperture of the mind, you know. The classic story that comes to mind is the one of Viktor Frankl or Nelson Mandela. You put somebody into a small box of confinement and... Some people break under those conditions and other people find entire stories within

• 34:17Andrew D. Huberman?

  a centimeter of concrete that can occupy them and real stories and richness or humor or love or fascination and surprise. And I find this so interesting that the mind is so adaptable. You know, we talked about creature comforts and then lack of creature comforts and the way that we can adapt. And yet, humans are always striving, it seems, or one would hope for these better conditions to better their conditions. So as you've come back, and you've been here now back in the in the States for how long after your trip?

• 34:48Lex Fridman?

  Depends on this podcast release, but it felt like I've never left. So practically speaking, a couple of months.

• 34:56Andrew D. Huberman?

  Yeah, and we won't be shy. We're recording this mid-September, so.

• 35:01Lex Fridman?

  We actually recorded this several years ago, so we're anticipating the future.

• 35:05Andrew D. Huberman?

  This is what we're gonna start telling you. This is a simulation. You and Joe. I'm still trying to figure out what that actually means.

• 35:11Speaker 01

  Mr. President, my company foreme of the explosion on our rig. On October 2nd. Causing massive water displacement and triggering a tsunami. They all keep the blame on me. Tom Cruise is.

• 35:23Speaker 02

  Digger got us into this mess, and Digger's gonna dig us out. From the director of Birdman and The Revenant.

• 35:29Speaker 03

  What would happen if I stopped drilling? You start, you freeze in there. That's what.

• 35:34Speaker 02

  With great power comes great deniability.

• 35:37Speaker 03

  I'm not the first then.

• 35:38Speaker 02

  Digger. See the trailer online. Only in theaters October 2nd. Rated R. Under 17. Not a minute without parent.

• 35:43Andrew D. Huberman?

  I know I speak for many people when I say that we are very happy that you're back. We know that it's not going to be the first and last trip, that there will be others, and that you'll be going to Russia as well, and presumably other places as well, in order to explore. And I have to say, as a podcaster and as your friend, I was really inspired that your sense of adventure and your sense of not just adventure, but thoughtful, respectful adventure. You understood what you were doing. You weren't just going there to get some wartime footage or something. This wasn't a kick or a thrill. This is really serious and remains serious. So, thank you for doing it. And please, next time you go, bring Tim Kennedy again.

• 36:27Lex Fridman?

  I feel like Tim Kennedy gets you into, we'll take it, because he really loves going to the most dangerous places and helping people. So I think he'd get me into more trouble than it's worth. And I should mention that.

• 36:40Lex Fridman?

  I mean, there's many reasons I went, but it's definitely not something I take lightly or want to do again.

• 36:46Andrew D. Huberman?

  Right.

• 36:46Lex Fridman?

  So I'm doing things that I don't want to do, I just feel like I have to.

• 36:50Andrew D. Huberman?

  You're compelled.

• 36:51Lex Fridman?

  So I don't think there's, now, I'll definitely talk about it, as we all should. There's different areas of the world that are seeing a lot of suffering. Yemen, there's so many atrocities going on in the world today, but this one is just personal to me, so I want to, I feel like I'm qualified just because of the language. So most of the talking, by the way, I've been, I was doing it, it was in Russian. And so because of the language, because of my history, I felt like I had to do this particular thing. I think it's in many ways stupid and dangerous, and that was made clear to me, but I do many things of this nature because the heart says, pulls, pulls towards that.

• 37:34Lex Fridman?

  But also, there's a, there's a freedom to not, you know, I'm afraid of death, but I think there's a freedom to, it's almost like, okay, if I die, I want to take full advantage of not having a family currently. I feel like when you have a family, there's a responsibility for others. So you immediately become more conservative and careful. I feel like I want to take full advantage of this particular moment in my life when you can be a little bit more accepting of risk, so.

• 38:07Andrew D. Huberman?

  Well, you should definitely reproduce at some point. Maybe before next time, you should just freeze some sperm.

• 38:14Lex Fridman?

  Really? Is that, is that what you do with the ice bath? Is that how that works?

• 38:17Andrew D. Huberman?

  You know, it's interesting, here's, there's always an opportunity to do some science protocols. You know, there are products on the internet, and there are actually a few decent manuscripts looking at how cold exposure can increase testosterone levels. But it doesn't happen by the cold directly. Good scientists, as the authors of those papers were and are, realize that it's the vasoconstriction and then the vasodilation, you know, as it, as people warm up again, there's increased blood flow to the testicles. And in women, it seems there's probably increased blood flow to the reproductive organs as well after people warm back up. So that seems to cause some sort of hypernourishment of the various cells, the...

• 38:59Andrew D. Huberman?

  Sertolian Leydig cells of the testes that lead to increased output of testosterone and in women, testosterone as well. So the cold exposure in any case is obviously a, do you do the ice bath? Are you into that?

• 39:13Lex Fridman?

  I've not done that.

• 39:13Andrew D. Huberman?

  As a Russian, you probably consider that a hot tub.

• 39:16Lex Fridman?

  Yeah, exactly. Yeah, it's a nice thing to have fun with every once in a while to warm up. No, I haven't done that. I've been kind of waiting to maybe do it together with you at some point.

• 39:27Andrew D. Huberman?

  Great. We have a guide. No, we have one here. It'll be straightforward for you. I always say that adrenaline comes in waves. And so if you just think about it, walls, like you're going through a number of walls of adrenaline as opposed to going for time, becomes rather trivial. With your jiu jitsu background and whatnot, you'll immediately recognize the physiological sensation, even though it's cold specifically. It's the adrenaline that makes you want to hop out of the thing.

• 39:49Lex Fridman?

  And you've seen Joe's, so Joe set up a really nice man cave. Or it's not even a cave because it's so big. It's like a network of man caves. But it has ice bath and a sauna next to each other. So.

• 40:04Andrew D. Huberman?

  We have one of those here, ice bath and sauna. So we'll have to get you in it when one of these days, maybe tonight, maybe tomorrow. No, although there is a, I don't know the underlying physiological basis, but there does seem to be a trend toward truth telling in the sauna. Some people refer to them as truth barrels, lines of barrel sauna, shaped like a barrel. Who knows why? Maybe under intense heat duress, people just feel compelled to share.

• 40:29Lex Fridman?

  I have a complicated relationship with saunas because of all the weight cutting.

• 40:34Andrew D. Huberman?

  Oh.

• 40:34Lex Fridman?

  Some of the deepest sufferings, sorry to interrupt, I've done was in the sauna. It's very, it's, I mean, I've gone to some dark places in the sauna because I wrestle my whole life, judo, jiu jitsu, and those weight cuts can really test the mind. So you're, truth telling. Yeah, it's a certain kind of truth telling because you're sitting there and the clock. Moves slower than it has ever moved in your life. Yeah, so I usually, for the most part, I would try to, you know, have a bunch of sweats, garbage bags and all that kind of stuff and run. It's easier because you can distract the mind. In the sauna, you can't distract the mind. It's just you and all the excuses and all the, all the weaknesses in your mind is coming

• 41:19Lex Fridman?

  to the surface and you're just sitting there sweating or not sweating. That's the worst.

• 41:24Andrew D. Huberman?

  And to talk about visual aperture, you're in a small box, so it also inspires some claustrophobia, even if you're not claustrophobic. That's absolutely true. And the desire to just get out of the thing is where the, you get a pretty serious adrenaline surge from, from in the sauna as well. Now, the sauna actually will, it won't deplete testosterone, but it kills sperm. So for people that, sperm are on a 60 day sperm cycle. So if you're trying to donate sperm or, because that's what got us onto this, or fertilize an egg or eggs in whatever format, dish or in vivo, as we say in science, which means, well, you can look it up, folks. The 60 day sperm cycle, so if you go into a really hot sauna or a hot bath or a hot

• 42:09Andrew D. Huberman?

  tub, you're, in 60 days, those sperm are going to be, a significantly greater portion of them will be dead, will be non-viable. So there's a simple solution, people just put ice pack down there or, you know, a jar, not this jar, but a jar of cold fluid, you know, between their legs and just sit there and, or they go back and forth between the ice bath and the sauna. But you probably, if you're going to go back over there, you should freeze sperm. We're going to do a couple of episodes on fertility when it's relatively inexpensive and you're young, so you should probably do it now because there is a association with autism as males get older. It's not a strong one, it's significant, but it's still a small contribution to the autism phenotype.

• 42:48Lex Fridman?

  As you age, don't sperm get wiser or no? There's no science to back that?

• 42:53Andrew D. Huberman?

  No, but you know, men can conceive healthy children at a considerable age, but in any case, but no, they don't get wiser. What happens is interesting.

• 43:02Lex Fridman?

  Finally aged steak.

• 43:03Andrew D. Huberman?

  Well, it's a little bit like, like the maturation of the brain in the sense that some of the sperm get much better at swimming and then many of them get, get less good. Motility is a, is a strong correlate of the DNA of the sperm.

• 43:14Lex Fridman?

  This is probably a good time to announce that I'm selling my sperm as an NFTs.

• 43:19Lex Fridman?

  See how much that

• 43:20Andrew D. Huberman?

  Oh my goodness.

• 43:21Lex Fridman?

  Writing the

• 43:22Andrew D. Huberman?

  Well, your children, your future children and my future children are supposed to do jujitsu together since I've only done the one jujitsu class. So I'm strongly vested in you having children.

• 43:33Lex Fridman?

  Yes.

• 43:34Andrew D. Huberman?

  But only in the friendly kind of way.

• 43:37Lex Fridman?

  Well, yes, friendly competition kind of way. Yeah.

• 43:40Andrew D. Huberman?

  Right.

• 43:40Lex Fridman?

  Dominance of the clan. Yep.

• 43:44Lex Fridman?

  For sure.

• 43:46Andrew D. Huberman?

  So, moving on to science, but still with our minds in the Ukraine. Did you encounter any scientists or see any universities? Or, you know, as we know, in this country and in Europe and in elsewhere, you know, science takes infrastructure, you need buildings, you need laboratories, you need robots, you need a lot of equipment and you need minus 80 freezers and you need incubators and you need money and you need technicians and typically it's been the wealthier countries that have been able to do more research for sake of research and development of and productization. Certainly the Ukraine had some marvelous universities and marvelous scientists.

• 44:29Andrew D. Huberman?

  What's going on with science and scientists over there? And, and gosh, can we even calculate the loss of discovery that is occurring as a consequence of this conflict?

• 44:41Lex Fridman?

  So, science goes on. The, before the war, Ukraine had a very vibrant tech sector that which means engineering and all that kind of stuff. And Kiev has a lot of excellent universities and they still go on. The, the biggest hit, I would say, is not the infrastructure of the science, but the fact because of the high morale, everybody is joining the military. So everybody's going to the front to fight, including, you know, you, Andrew Huberman, would be fighting and not because you have to, but because you want to. And everybody you know would be really proud that you're fighting, even though everyone tries to convince, you know, Andrew Huberman, you have much better ways to contribute.

• 45:25Lex Fridman?

  There's deep honor in fighting for your country, yes, but there are better ways to contribute to your country than just picking up a gun that you're not that trained with and going to the front. Still, they do it. Scientists, engineers, CEOs, professors, students. Men and women. Actors. Men and women. Obviously, primarily men, but men and women. Like, much more than you would see in other militaries, women are everybody. Everybody wants to fight. Everybody's proud of fighting. There's no discussion of kind of pacifism. Should we be fighting? Should this right? Is this, you know, it's everybody's really proud of

• 46:09Lex Fridman?

  fighting. So that's a, so there's this kind of black hole that pulls everything, all the resource into the war effort. That's not just financial, but also psychological. So it's like, if you're a scientist, it feels like, well, it feels like, almost like you're dishonoring humanity by continuing to do things you were doing before. There's a lot of people that converted to being soldiers. They literally watch a YouTube video of how to shoot a particular gun, how to arm a drone with a grenade. You know, if you're a tech person, you know how to work with drones. So you're going to use that, use whatever

• 46:52Lex Fridman?

  skills you got. Figure out whatever skills you got and how to use them to help the effort on the front. And so that's a big hit. But that said, that, you know, I've talked to a lot of folks in Kiev, faculty, primarily in the tech economics space. So I didn't get a chance to interact with folks who are on the biology, chemistry, neuroscience side of things, but that, that, that still goes on. So one of the really impressive things about Ukraine is that they're able to maintain infrastructure, like road, food supply, all that kind of stuff, education while the war is going on, especially in Kiev. The war started where nobody knew whether Kiev was going to be taken by the Russian forces. It was surrounded. And

• 47:40Lex Fridman?

  A lot of experts from outside were convinced that Russia would take Kiev. And they didn't. And one of the really impressive things as a leader, one of the things I really experienced is that a lot of people criticized Zelensky before the war. He only had about like 30% approval rate. A lot of people didn't like Zelensky. But one of the great things he did as a leader, which I'm not sure many leaders will be able to do, is when Kiev was clearly being invaded, he chose to stay. He stayed in the capital. Everybody, all the American military,

• 48:20Lex Fridman?

  the intelligence agencies, NATO, his own staff, advisors, all told him to flee and he stayed. And so that's, I think that was a beacon, a symbol for the rest, for the universities, for science, for the infrastructure that we're staying to. And that kept the whole thing going. There's an interesting social experiment that happened. I think for folks who are interested in sort of gun control in this country in particular, is one of the decisions they made early on is to give guns to everybody. Semi-automatics.

• 48:55Andrew D. Huberman?

  Early on in the war?

• 48:56Lex Fridman?

  Early on in the war, yeah. So everybody got a gun. They also released a bunch of prisoners from prison because there was no staff to to keep the prisons running. And so there's a very interesting psychological experiment of like, how is this gonna go? Everybody has a gun. Are they gonna start robbing places? Are they going to start taking advantage of a chaotic situation? And what happened is that crime went to zero. So it turned out that this, as an experiment, worked wonderfully.

• 49:32Andrew D. Huberman?

  That's a case where love generalized.

• 49:34Lex Fridman?

  Yes.

• 49:34Andrew D. Huberman?

  Or at least hate did not. We don't know if it's love or it's sort of lack of initiative or self, you know, common culture directed hate.

• 49:41Lex Fridman?

  Yeah, I don't, right, it's, I think that's very correct to say that it wasn't hate that was unifying people. It was love of country, love of community. It's the, probably the same thing that will happen to humans when like aliens invade. It's, we're all, it's the common effort. Everybody puts everything else to the side. Plus, just the sheer amount of guns. It's similar to like Texas, you realize like, well, there's going to be a self correcting mechanism very quickly because the rule of law was also put aside, right? Like, um, basically, the police force lost a lot of power because everybody else has guns and they're kind of taking the law into their own hands.

• 50:24Lex Fridman?

  And that system, at least in this particular case, in this particular moment in human history, worked. It's an interesting lesson, you know?

• 50:32Andrew D. Huberman?

  I did, it is. I had an interesting contrast that I'll share with you, I, because you mentioned Texas. So not so long ago, I was in Austin, often visit you or others in Austin, as you know, and many doors that I walked past, including a school, said, um, no firearms past this point, you know, there's a sticker on the door. You see this on hospitals sometimes, I saw this at Baylor College of Medicine, et cetera. Relatively common to see in Texas, um, not so common in California. And then I flew to the San Francisco Bay area, was walking by an elementary school in my old neighborhood and saw a similar sticker and looked at it and it said, um, no peanuts

• 51:14Andrew D. Huberman?

  or other allergy containing foods past this point on the door of this elementary school. So quite a different contrast, like, you know, guns and peanuts. Um, now peanut allergies obviously are very serious for some people, although there's great research out of Stanford showing that early exposure to peanuts, um, can prevent the allergies, it's, uh, but don't start rubbing yourself in peanut butter, folks, if you have a peanut allergy, that's not the best way to deal with it. In any case, the contrast of what's dangerous, the contrast of, um, you know, the familiarity with guns versus no familiarity, you know, in Israel and elsewhere, you see machine guns in the airport, in Germany, Frankfurt, you see machine guns in the airport, not so common in the United States.

• 51:56Andrew D. Huberman?

  So again, there's, I feel like there's this aperture of vision, there's this aperture of pleasures and versus creature comforts and lack of, uh, creature comforts. And then there's this aperture of, of danger, right? Um, people who are familiar with guns, you know, are familiar with people coming in and setting their firearm on the table and eating, eating dinner, you know, but in, if you're not accustomed to that, it's jarring, right?

• 52:18Lex Fridman?

  I should mention, people know this throughout human history, but the human ability to,

• 52:26Lex Fridman?

  Get assimilated, no, get used to violence is incredible. So like you could be living in a peaceful time like, like we're here now. And there'll be one explosion, like a nine 11 type of situation. That'd be a huge shock, terrifying, everybody freaks out. The second one is a huge drop off in how freaked out you get. And within a matter of days, sometimes hours, it becomes the normal. I've talked to so many people in Heart Cave, which is one of the towns that's seen a lot of heated battle. You ask them, is it safe there? In fact, when I went to the closer and closer to the war zone, you ask people, is it safe?

• 53:10Lex Fridman?

  And their answer is usually, yeah, it's pretty safe.

• 53:13Andrew D. Huberman?

  It's all signal the noise.

• 53:15Lex Fridman?

  Yeah, it like, nobody has told me, except like Western reporters, sitting in the west side of Ukraine. It's really dangerous here. Everyone's like, yeah, you know, it's good. Like, uh, my uncle just died yesterday, like he was shot. But it's pretty, you know, it's pretty good, like the farm's still running, like they, um, how do I put it? They focus on the positive, that's one, but it's, there's a deeper truth there, which is you just get used to difficult situations and the stuff that make you happy and the stuff that make you upset is relative to that new normal that you establish.

• 53:53Andrew D. Huberman?

  Well, I grew up in California and there were a lot of earthquakes. I remember the 89 quake, I remember the Embarcadero freeway pancaking on top of people and cars. I remember, um, I moved to Southern California, there's a North Ridge quake. Wherever I move, there seem to be earthquakes. I never worry about earthquakes, ever. I just don't, in fact, I don't like the destruction they cause, but every once in a while, an earthquake will roll through and it's kind of exciting. It sounds like a train coming through, it's like, wow, like the earth is moving, you know? Again, I don't want anyone to get harmed, but I enjoy a good rumble coming through nonetheless. It signaled the noise, but if I saw a tornado, freak out. And people from the Midwest are probably comfortable with, you know, Dan Gable, the great wrestler from the Midwest, that you know, and I've never met, but I have great respect for. He's probably, you know, sees tornadoes, like, ah, yeah, maybe, you know?

• 54:37Andrew D. Huberman?

  You know, so, so I think signal the noise is, is real.

• 54:42Andrew D. Huberman?

  Before I neglect, although I won't forget, speaking of signal the noise and environment, you are returning to or have gone back to one of your original natural habitats, which is the Massachusetts Institute of Technology.

• 54:59Lex Fridman?

  Natural Habitat.

• 55:00Andrew D. Huberman?

  It's actually difficult to pronounce in full, MIT, right? So you've been spending some time there, teaching and doing other things. Tell us what you're up to with MIT recently.

• 55:09Lex Fridman?

  Well, it's, I'm really glad that you, being on the West Coast, know the difference between like Boston, New York. I feel like a lot of people think it's like the East Coast.

• 55:18Andrew D. Huberman?

  It's very different, especially to Bostonians and New Yorkers.

• 55:22Lex Fridman?

  They get very aggressive.

• 55:23Andrew D. Huberman?

  Oh, my goodness.

• 55:24Lex Fridman?

  Yeah, I love it. I get, I gave lectures there in front of an in-person crowd.

• 55:30Andrew D. Huberman?

  What were you talking about?

• 55:31Lex Fridman?

  For the AI, so different aspects of AI. And, you know, robotics, machine learning, machine learning. So for people who know the artificial intelligence field, they usually don't use the term AI. And the people from outside use AIs. The biggest breakthroughs in the machine learning field was some discussion of robotics and so on. Yeah, it was in-person is wonderful. I'm a sucker for that. I really avoided teaching or any kind of interaction during COVID because people put a lot of emphasis on, but also got comfortable with remote teaching. And I think nobody enjoyed it, except sort of there's a notion that it's much easier to do

• 56:16Lex Fridman?

  because you don't have to, you know, you don't have to travel. You don't have to, you can do it in your pajamas kind of thing. But when you actually get to do it, you don't get the same kind of joy that you do when you're teaching. As a student, you don't get the same kind of joy of learning. It's not as effective and all that kind of stuff. So to be in-person together with people, to see their eyes, to get their excitement, to get the questions and all the interactions, that was awesome. And I'm still. A sucker and a believer in the the ideal of MIT of the university. I think it's an incredible place. There's something in the air still, but it really hit. The pandemic hit universities hard because, and I can say this, this is not you saying it.

• 57:00Lex Fridman?

  This is me saying it, that administrations, as in all cases when people criticize institutions, the pandemic has given more power to the administration and taken away power from the faculty and the students. And that's from everybody involved, including the administration. That's a concern because the university is about the teachers and the students. That should be primary. And whenever you have a pandemic, there's an opportunity to increase the amount of rules. Like, one of the things that really bothered me, and I'll scream from the top of the MIT dome about this, is they've instituted a new tim ticket system, which is if you're a visitor to the campus at MIT, you have to register.

• 57:43Lex Fridman?

  You have to, first of all, show that you're vaccinated, but more importantly, there's a process to visiting. You need to get permission to visit. One of the reasons I loved MIT, unlike some other institutions, MIT just leaves the door open to anyone.

• 58:01Lex Fridman?

  In classrooms, you can roll in the ridiculous characters, the students that are kind of like usually doing business stuff or economics can roll into a physics class and just, you know, you're kind of not allowed, but it's a great area. So you let that happen, and that creates a flourishing of the community that was beautiful. And I think adding extra rules puts a squeeze on and limits some of the flourishing. And I hope some of that dissipates over time as we kind of let go of the risk aversion that was created by the pandemic as we kind of enter the new, the normal, return back, some of that flourishing can happen. But when you're actually in there.

• 58:43Lex Fridman?

  With the students, yeah, it was magic. I love it. I love it.

• 58:47Andrew D. Huberman?

  Well, some of your earliest videos on your YouTube channel were of you in the classroom, right? That's how this all started.

• 58:53Lex Fridman?

  Yeah, yeah, it's all YouTube. Like, putting stuff on YouTube is terrifying, right?

• 58:59Andrew D. Huberman?

  Well, especially at the time when you did it again, you're a pioneer in that sense. You did that, Jordan Peterson did that. Putting up lectures is... Yeah, I would... I teach still. Every winter I teach, direct a course, and I'll be doing even more teaching going forward. But the idea of those videos being on the web is, yeah, that spikes my cortisol a little bit.

• 59:24Lex Fridman?

  Yeah, it's terrifying because you get to... And everybody has a different experience. Like, for me, being a junior research scientist, the kind of natural concern is like, who am I? And when I was giving this lecture, it's like, I don't deserve any of this.

• 59:40Andrew D. Huberman?

  Yeah, but that's your humility coming through. And I actually think that humility on the part of an instructor is good because those that think, you know, that they are entitled and who else could give this lecture, then I worry more. I think it's... I once heard, I don't know if it's still true, that the, at Caltech, right, the great California Institute of Technology, not far from here, that many of the faculty are actually afraid of the students. Not physically afraid, but they're intellectually afraid because the students are so smart.

• 1:00:10Lex Fridman?

  Yeah.

• 1:00:11Andrew D. Huberman?

  And teaching there can be downright frightening, I've heard. But that's great. Keeps everybody on their toes. And I think, and you know, I've been corrected in lecture before at Stanford and elsewhere. You know, when my lab was at UC San Diego, where someone will say, hey, wait, you know, last lecture you said this, and now you said that. And we're on the podcast, you know, and I think it's that moment where, you know, you sometimes feel that urge to defend you. Oh, you're right. And I think it depends on how one was trained. My graduate advisor was wonderful at saying, "I don't know," all the time. And she went to Harvard, Radcliffe, UCSF, and Caltech, a brilliant woman, and had no problem saying like, "I don't know."

• 1:00:50Lex Fridman?

  I don't have that problem. So I usually have two guys that if somebody speaks up, grab them, drag them out of the room, never see them again. So everybody is really supportive. I don't understand the amount of love and support I get.

• 1:01:03Andrew D. Huberman?

  Especially when the last few students are there and everybody seems to be nodding. No, I think that I'd love to sit in on one of your lectures. I know very little about AI, machine learning or robotics.

• 1:01:14Lex Fridman?

  Have you ever talked at MIT? Have you ever like given lectures?

• 1:01:18Andrew D. Huberman?

  Oh, yeah. When I went on the job market as a faculty member, my final two choices were between MIT Peacock. I had an on paper offer, wonderful place, wonderful place to do neuroscience and UC San Diego, which is a

• 1:01:32Andrew D. Huberman?

  wonderful neuroscience program. In the end, it made sense for me to be on the West Coast for personal reasons. But there's some amazing neuroscience going on there, goodness. And that's always been true and is going to continue. It's been a long time since I've been invited back there. Oddly enough, when I started doing more podcasting and I still run a lab, but I shrunk my lab considerably when I was doing, as I've done more podcasting, I've received fewer academic lecture invites, which makes sense. But now they're sort of coming back. And so when people invite now, I always say, you know, do you want me to talk about the ventral thalamus and its role in anxiety and aggression? Or do you want me to talk about the podcast? And my big fear is I'm going to go back to give a lecture about the retina or something and I'll start off with an Athletic Greens read or something like that, just reflexively.

• 1:02:17Andrew D. Huberman?

  Just kidding, that wouldn't happen. But listen, I think it's great to continue to keep a foot in both places. I was so happy to hear that you're teaching at MIT because podcasting is one thing, teaching is another. And there's overlap there in the Venn diagram. But listen, the students that get to sit in on one of your lectures and you may see me sitting there in the audience soon when I creep into your class.

• 1:02:38Lex Fridman?

  Sunglasses.

• 1:02:39Andrew D. Huberman?

  That's right, wearing a red shirt. You won't recognize me. We're certainly receiving a great gift. I've watched your lectures on YouTube, even the early ones. And listen, I know you to be a phenomenal teacher.

• 1:02:53Lex Fridman?

  Yeah, there's something about, so I'm also doing like, I stayed up pretty late last night, working for a deadline on a paper. One of the things that I hope to do for hopefully the rest of my life is to continue publishing. And I think it's really important to do that, even if you continue the podcast, because you want to be just on your own intellectual and scientific journey as you do podcasting. At least for me, and especially on the engineering side, because I want to build stuff. And I think that's like keeps your ego in check, keeps you humble.

• 1:03:35Lex Fridman?

  Because I think if you talk too much on the microphone, you start getting, you might lose track of the grounding that comes from engineering, from science and the scientific process and the criticisms that you get, all that kind of stuff.

• 1:03:49Andrew D. Huberman?

  And how slow and iterative it is. We have two papers right now that are in the revision stage. It's been a very long road. And I was asked this recently because I met with my chairman. He said, do you want to continue to run a lab or are you just going to go full time on the podcast? And Stanford has been very supportive, I must say, as I know MIT has been of you. And I said, oh, I absolutely want to continue to be involved in research and do research. And we started talking about these papers and we're looking over my, this was my yearly review and looking back, like goodness, these papers have been in play for a very long time. So it's a long road, but you learn more and more. And the more time you spend myopically looking at a bunch of data, the more you learn and the more you think. I totally agree. Talking to these devices for podcasts is wonderful because it's fun. It relieves a certain itch that we both have.

• 1:04:33Andrew D. Huberman?

  And hopefully it lands some important information out there for people. But doing research is like the, you know, I guess if you know, you know, there's like the, you know, the unpeeling of the onion, knowing that there could be something there. There's just nothing like it.

• 1:04:50Lex Fridman?

  I mean, you do, especially with the pandemic. And for me, both Twitter and the podcast have made me much more impatient about the slowness of the review process.

• 1:05:02Andrew D. Huberman?

  Twitter will do that.

• 1:05:04Lex Fridman?

  Twitter will do that, but even with podcasts, you have a cool, you'll find something cool and then you have ideas and all, and you'll just say them and they'll be out pretty quickly.

• 1:05:13Andrew D. Huberman?

  Yeah, we do a post right now about something that we both found interesting and it's out in the world, yep.

• 1:05:17Lex Fridman?

  And you can write up something like, there is a culture in computer science of posting stuff on archives and pre-prints that don't get any review and sometimes they don't even go through the review process ever, because like people just start using them if it's code. And it's like, what was, what's the point of this? It works, like the, it's self-evident that it works because people are using it. And that, that I think applies more to engineering fields because it's an actual tool that works. It doesn't matter if, you don't have to scientifically prove that it works. It works because using for a lot of people.

• 1:05:49Andrew D. Huberman?

  Well, sorry to interrupt, but I just, for point of reference, the famous paper describing the double helix, which earned Watson and Crick the Nobel Prize and should have earned Rosalind Franklin Nobel Prize too, of course, but they got it for the structure of DNA, of course. That paper was never reviewed at Nature. They published it because its importance was self-evident or whatever.

• 1:06:10Lex Fridman?

  Oh, interesting. So like the editors.

• 1:06:12Andrew D. Huberman?

  It was that purely editorial decision, I believe. I mean, that's what I was told by someone who's currently an editor at Nature. If that turns out to not be correct, someone will tell us in the comments for sure.

• 1:06:22Lex Fridman?

  Well, I think.

• 1:06:23Andrew D. Huberman?

  That's pretty interesting, right?

• 1:06:24Lex Fridman?

  That's really interesting.

• 1:06:25Andrew D. Huberman?

  Perhaps the most significant discovery in biology and bioengineering, which leading to bioengineering as well, of course, of the last century, was not peer reviewed.

• 1:06:35Lex Fridman?

  Yeah, but so Eric Weinstein, but many others have, have talked about this, which is, I mean, I don't think people understand how.

• 1:06:47Lex Fridman?

  Poor the peer review processes, just the amount of, because you think peer review, it means all the best peers get together and they review your stuff. But it's unpaid work and it's usually a small number of people and it's a very, they have a very select perspective, so they might not be the best person, especially if it's super novel work.

• 1:07:06Andrew D. Huberman?

  And it's who has time to do it. I'm on a bunch of editorial boards still. Why, I don't know, but I enjoy the peer review process and sending papers out. Oftentimes, the best scientists are very busy and don't have time to review. And oftentimes, the more premier journals will select from a kind of a unique kit of very good scientists who are very close to the work. Sometimes the people are very far from the work. It really depends.

• 1:07:30Lex Fridman?

  And both have negatives, right? If you're very close to the work, there's jealousy and all those basic human things. Very far from the work, you might not appreciate the nuance, contribution, all that kind of stuff.

• 1:07:40Andrew D. Huberman?

  And there's psychology. Sorry to interrupt again, but a good friend of mine who's extremely successful neuroscientist, Howard Hughes investigator, et cetera, always told me that they, I won't even say whether or not, who they are, they select their reviewers on the basis of who has been publishing very well recently, because they assume that that person is going to be more benevolent because they're, they've been doing well, so that the, the love expands.

• 1:08:02Lex Fridman?

  There's a good point to that, actually. But, you know, the, the idea is that editors might actually be the best reviewers. So that, that was the traditional, that's, that's the thing I wanted to mention that Eric Weinstein talks about, that back several decades ago, editors had much more power. And there's something to be made for that, because they, editors are the ones who are responsible for crafting the journal, like, they really are invested in this. And so, and they're also often experts, right? So it makes sense for an editor to have a bit of power in this case. Like, usually, if an idea is truly novel, you could see it. And so it's, it makes sense for an editor to have more power in that regard.

• 1:08:44Lex Fridman?

  Of course, for me, I, I think peer review should be done the way tweets are done, which is like crowdsourced or Amazon reviews.

• 1:08:51Andrew D. Huberman?

  Let the crowd decide.

• 1:08:52Lex Fridman?

  Let the crowd decide. And let, let the crowd add.

• 1:08:57Lex Fridman?

  Depth and breadth in context for the contribution. So, you know, if the paper overstates the degree of contribution, the crowd will check you on that. If there's not enough support or like the conclusions are not supported by the evidence, the crowd will check you on that. There should, there could be, of course, a political bickering that enters the picture, especially on very controversial topics. But I think I trust the intelligence of human beings to figure that out. And I think most of us are trying to figure this whole process out. I just wish it was happening much faster because on the important topics, the review cycle could be, could be faster.

• 1:09:38Lex Fridman?

  And we learned that through COVID, that Twitter was actually pretty effective at doing science communication. It was really interesting. Some, some of the best scientists took to Twitter to communicate their own work and other people's work. And always putting into sort of the caveats, it's not peer reviewed and so on, but it's, it's all out there. And the data just moves so fast. And if you want stuff to move fast, Twitter is the best medium of communication for that. It's cool to see.

• 1:10:07Andrew D. Huberman?

  I'm now on Twitter more regularly. And initially it was just Instagram. And I remember you and I used to have these over, over dinner drink conversations where I'd say, I don't understand Twitter. And you'd say, I don't understand Instagram. And of course, we understand how it worked and how to work each respective platform. But I think we were both trying to figure out, you know, what is driving the psychology of these different venues? Cause they are quite distinct psychologies. For whatever reason, I think I'm finally starting to understand Twitter and enjoy it a little bit. Initially, I wasn't prepared for the level of kind of reflexive scrutiny. That it sounds a little bit oxymoronic, but that people kind of like pick up on one small thing and then, you know, drive it down that, that trajectory.

• 1:10:51Andrew D. Huberman?

  It didn't seem to be happening quite as much on Instagram, but I love your tweets. I, I do have a question about your, your, your Twitter account and how you, do you have sort of internal filters of what you'll put up and won't put up? Because sometimes you'll. Put up things that are about life and reflections. Other times you'll put up things like what you're excited about in AI, or of course, you know, point to various podcasts, including your own, but others as well. You know, what do you, how do you approach social media? Not how do you regulate your behavior on there in terms of how much time, etc. I know you've talked about that before, but you know, what's your mindset around social media when you go on

• 1:11:30Andrew D. Huberman?

  there to either post or forage or respond to information?

• 1:11:37Lex Fridman?

  I think I try to add some, not to sound cliche, but some love out there into the world, into, as OJ Simpson calls it, Twitter world. I think there is this viral negativity that can take hold, and I try to find the right language to add, you know, good vibes out there. And it's actually really, really tricky, because there's something about positivity that sounds fake. And I'm not, I can't quite put my finger on it, but whenever I talk about love and positive, and almost childlike in my curiosity and positivity, people are, start to think like,

• 1:12:22Lex Fridman?

  surely, he has like skeletons in the closet, like there's dead bodies in his basement. Like, this must be a fake-

• 1:12:29Andrew D. Huberman?

  It's the attic.

• 1:12:31Lex Fridman?

  It's the attic?

• 1:12:31Andrew D. Huberman?

  The attic.

• 1:12:32Lex Fridman?

  I keep mine in the basement. That's the details.

• 1:12:35Andrew D. Huberman?

  I was referring to your attic. I don't have an attic or a basement.

• 1:12:37Lex Fridman?

  Oh.

• 1:12:37Andrew D. Huberman?

  Nor dead bodies. I just want to be very clear.

• 1:12:39Lex Fridman?

  Yeah. I do have an attic, and actually haven't been up there. Maybe there is bodies up there. But yes, I prefer the basement. It's colder down there. I like it. No, but there's an assumption that this is not genuine, or not, it's disingenuous in some kind of way. And so I try to find the right language for that kind of stuff, how to be positive. Some of it, I was really inspired by Elon's approach to Twitter. Not all of it, but the, when he just is silly. I found that silliness-

• 1:13:16Lex Fridman?

  I think it's Herman Hesse said something to paraphrase, one of my favorite writers.

• 1:13:24Andrew D. Huberman?

  Yeah, same.

• 1:13:25Lex Fridman?

  I think in Steppenwolf said, "Learn what is to be taken seriously and laugh at the rest." I think I try to be silly, laugh at myself, laugh at the absurdity of life. And then in part, when I'm serious, try to just be positive, just see a positive perspective. But, and also, as you said, people pick out certain words and so on, and they attack each other, attack me over certain usage of words and a particular tweet. I think the thing I try to do is think positively towards them, like do not escalate. So whenever somebody's criticizing me and so on, I just smile.

• 1:14:10Lex Fridman?

  If there's a lesson to be learned, I learn it and then I just send good vibes their way, don't respond, and just hopefully sort of through karma and through kind of the ripple effect of positivity have like, you know, an impact on them and the rest of Twitter. And what you find is like, that builds, your actions create the community. So how I behave gets me surrounded by certain people. But, you know, lately, especially Ukraine is one topic like this. I also thought about talking to, somebody who reached out to me is Andrew Tate, who's extremely controversial, from the perspective of a lot of people, is a misogynist.

• 1:14:54Andrew D. Huberman?

  And I've heard his name and I know that there's a lot of controversy around him. Maybe you could familiarize me. I've been pretty nose down in podcast prep and I tried to do this vacation thing for about three, four weeks.

• 1:15:06Lex Fridman?

  I've heard about that.

• 1:15:07Andrew D. Huberman?

  Yeah, and it sort of worked. I did get some time in the Colorado wilderness by myself, which was great. I did get some downtime, but in any event, it mainly consisted of reading and.

• 1:15:23Lex Fridman?

  In nature.

• 1:15:25Andrew D. Huberman?

  Reading and nature, sauna, ice bath, working out, good food, a little extra sleep, these kinds of things. I really felt I needed it, but I am. Pretty naive when it comes to the kind of current controversies, but I've heard his name and I think he's been deplatformed on a couple of platforms. Do I have that right?

• 1:15:44Lex Fridman?

  It's been, so I should also admit that while I might know more than you, it's not by much. So it's like, it's like a five year old talking to a four year old right now.

• 1:15:54Andrew D. Huberman?

  Is he an athlete, a podcaster?

• 1:15:56Lex Fridman?

  So, uh, basic summary, he used to be a fighter, a kickboxer, I believe, was pretty successful. And then during that and after that, I think he was in a reality show and he had all these programs that are basically like pick up artist advice. He has this like community of people where he gives advice on how to pick up women, how to, how to be successful in relationships, how to make a lot of money. And there's like, um, it costs money to enter that, those programs. So a lot of the criticism that he gets is kind of, uh, it's like a pyramid scheme where you convince people to join so that they

• 1:16:38Lex Fridman?

  can make more money and then they convince others to join that kind of stuff. But that's not why I'm interested in talking to him. I'm, I'm interested because one of the guests, maybe I shouldn't mention who, but like one of the female guests I had, really a big scientist said that her, uh, two kids that are 13 and 12 really look up to Andrew.

• 1:17:01Andrew D. Huberman?

  These are male children, female children?

• 1:17:03Lex Fridman?

  Yeah, male. And I hear this time and time again. So like, he is somebody that a lot of teens, young teens look up to. So I haven't done serious research. Like I, I usually try to avoid doing research until I like agree to talk and then I go deep. But there is an aspect to the way he talks about women that while I understand and I understand certain dynamics in relationships work for people and he's one of such person. But I think him being really disrespectful towards women is not what I.

• 1:17:47Lex Fridman?

  It's not how I see what it means to be a good man. So the conversation I want to have with him is about masculinity. What does masculinity mean in the 21st century? And so when I think about that kind of stuff, and because we're talking about Twitter, it's like going into a war zone. I'm like a happy go lucky person, but you're not.

• 1:18:10Andrew D. Huberman?

  Send me to the Ukraine, but I don't want to have this conversation on Twitter.

• 1:18:13Lex Fridman?

  Because it's a really, really, really tricky one. Because also, as you know, when you sit, when you do a podcast, like, everybody wants you to, um, to win. And like, there's not a, it's, everything you do is positive. Maybe you'll say the wrong thing, it's like inaccurate thing, and you can correct yourself. With Andrew Tate, with Donald Trump, with folks like this, you have to, I mean, it's a professional boxing. Like, you have to push the person, you have to be really eloquent. You have to be also sympathetic, because you can't just do what journalists do, which is talk down to the person the entire time. That's easy.

• 1:18:52Lex Fridman?

  The hard thing is to empathize with the person, to understand them, to steel man their case, but also to make your own case. So in that case, about what it means to be a man, to me, a strong man is somebody who's respectful to women. Not out of weakness, not out of social justice warrior signaling and all that kind of stuff, but out of, that's what a, a strong man does. Like, they don't need to be disrespectful to prove their position in life. He is often, now, a lot of people say it's a character. It's, it's, he's being misogynistic, he's being a misogynist as a kind of, for entertainment purposes.

• 1:19:27Andrew D. Huberman?

  So like an avatar?

• 1:19:28Lex Fridman?

  Yeah. But to me, that avatar is, has a lot of influence on young folks. So the character has, has, um,

• 1:19:38Lex Fridman?

  Has impact.

• 1:19:39Andrew D. Huberman?

  Oh, I don't think you can separate the avatar and the person in terms of the impact. As you said, in fact, there are a number of accounts on Twitter and Instagram and elsewhere, which people have only revealed their first names, or they give themselves another name, or they're using a cartoon image. And part of that, I believe, and at least from some of these individuals who actually know who they are, I understand as, A, an attempt to maintain their privacy, which is important to many people, and in some cases, so that they can be more inflammatory, and then just pop up elsewhere as something else without anyone knowing that it's the same person.

• 1:20:17Lex Fridman?

  Some of the, this is the dark stuff. I've been reading a lot about Ukraine and Nazi Germany, so the 30s and the 40s and so on, and you get to see how much the absurdity turns to evil quickly. One of the things I worry, one of the things I really don't like to see on Twitter and the internet is how many statements end with LOL. It's like, you think just because something is kind of funny, or is funny, or is legitimately funny, it also doesn't have a deep effect on society. So that's such a difficult gray area, because some of the best comedy is dark and mean, but it reveals some important truth that we need to consider.

• 1:21:02Lex Fridman?

  But sometimes comedy is just covering up for destructive ideology. And you have to know the line between those two. Hitler was seen as a joke in the late 20s and the 30s, the Nazi Germany, until the joke became very serious. You have to be careful to know the difference between the joke and the reality, and do all that, I mean, in a conversation, I'm just such a big believer in conversation, to be able to reveal something through. Conversation, but I don't know, one of the big, you know, you and I challenge ourselves all the time. I don't know if I, I have what it takes to have a, a good, empathetic, but adversarial conversation.

• 1:21:47Andrew D. Huberman?

  I need to, um, learn more about this Tate person, or not learn about him. Yeah, it sounds, it sounds like maybe it's something to skip. I don't know. Cause again, I'm not familiar with the content, but I was gonna ask you, um, whether or not you've seeked out, or whether or not you would ever consider having Donald Trump as a guest on your podcast.

• 1:22:05Lex Fridman?

  Yeah, I, I've talked to Joe a lot about this. And, um,

• 1:22:13Lex Fridman?

  I, I re- I really believe I can have a good conversation with Donald Trump. I, but

• 1:22:22Lex Fridman?

  I haven't seen many good conversations with him. So like, um, part of me thinks, part of me believes it's possible, but he often effectively runs over the interviewer.

• 1:22:36Andrew D. Huberman?

  You know, you can sit him down, give him an element, an athletic greens.

• 1:22:39Lex Fridman?

  Just relax.

• 1:22:40Andrew D. Huberman?

  I mean, that nice, cool, air-conditioned, uh, black curtain studio you've got and, uh, you know, a different side might come out. Context is powerful.

• 1:22:49Lex Fridman?

  Well, uh, Joe's really good at this, which is relaxing person, you know, like, here, have a drink, right? Smoke a joint, or whatever it is, but some, this energy of just, let's relax and there's laughter and so on. I don't think, um, as people know, I'm just not good at that kind of stuff. So I think the way I could have a good conversation with him is to really understand his worldview, be able to steal man's worldview and those that support him, which is, I'm sorry to say, for people who seem to hate Donald Trump, is a very large percentage of the country. And so you have to really empathize with those people. You have to empathize with Donald Trump, the human being, and from that

• 1:23:33Lex Fridman?

  perspective, ask him hard questions.

• 1:23:37Andrew D. Huberman?

  Who, who do you think is the, is the counterpoint? If you're gonna see, you know, seek balance in your guests, if you're gonna have Trump on, then you have to have who on?

• 1:23:46Lex Fridman?

  Well, that's interesting.

• 1:23:48Andrew D. Huberman?

  Anthony Fauci? Seems to be, uh, you know, strongly associated with, um, sort of counter-values, at least in the, in the eye of the public. I think he's retiring soon, but.

• 1:23:59Lex Fridman?

  I, yeah, he's retiring soon. That's really interesting. Anthony Fauci. Yeah, definitely, but I don't think he's a counterbalance. He's a, he's a complicated, fascinating figure who seems to have attracted a lot of hate and distrust.

• 1:24:15Andrew D. Huberman?

  And love from some people.

• 1:24:16Lex Fridman?

  And love.

• 1:24:17Andrew D. Huberman?

  And love from some people. I mean, I know people, not even necessarily scientists, who have, you know, pro Fauci shirts. I've seen people with anti Fauci shirts, shirts, excuse me, but certainly, but who adore him. There are people who adore him, in the same way there are people that adore Trump. It's so interesting that, you know, one species of animal, it's got such divergent neural circuitry.

• 1:24:39Lex Fridman?

  It's almost feels like it's by design and every single topic we find tension and division. It's fascinating to watch. I mean, I got to really witness it from zero to a hundred in Ukraine, where there's not huge, significant division.

• 1:24:57Lex Fridman?

  There was in certain parts of Ukraine, but across Europe, across the world, there was not that much division between Russia and Ukraine. And it was just born overnight, this intense hatred. So, and you see the same kind of stuff with Fauci over the pandemic. At first, we're all kind of huddled in uncertainty. Kind of, there is a togetherness with that pandemic. Of course, there is more difficult because you're isolated. But then you start to figure out, like, the, probably the politicians and the media try to figure out, how can I take a side here? And how can I now start reporting on this side or that side? And say how the other side is wrong. And so I think Anthony Fauci is a part of

• 1:25:40Lex Fridman?

  just being used as a scapegoat for certain things, as part of that kind of narrative of division. But I think, so Trump is a singular figure that, to me, represents something important in American history. I'm not sure what that is. But I think you have to think, you put on your historian hat, go forward in time and think back. Like, how will he remember, be remembered 20, 30, 40, 50 years from now? Who is the opposite of that?

• 1:26:12Lex Fridman?

  You have to, I, I would really have to think about that because, because Trump was so singular. I think ALC is an interesting one, but she's so young, it's unclear to know how, what, if she represents a legitimately large scale movement or not. Bernie Sanders is an interesting option, but I wish he would be 30, 40 years younger, like the young Bernie would be a good.

• 1:26:37Andrew D. Huberman?

  There are scientists working on that.

• 1:26:38Lex Fridman?

  Yeah, I think so.

• 1:26:42Andrew D. Huberman?

  Not him specifically, but.

• 1:26:44Lex Fridman?

  Well, yeah, it may be him, we never know. There is a big conspiracy theory that Putin is, that is, that's a body double. It's no longer.

• 1:26:54Andrew D. Huberman?

  Bernie is Putin?

• 1:26:55Lex Fridman?

  No, no, no.

• 1:26:56Andrew D. Huberman?

  I'm having a hard time.

• 1:26:58Lex Fridman?

  The conspiracy theories, no, no, no, that the Putin we see on camera today is a body double.

• 1:27:05Andrew D. Huberman?

  Well, one thing that, you know, in, in science and in particular in anatomy, there's a classification scheme for different types of anatomists, which they either say you're a lumper or a splitter. You know, some people like to call a whole structure something, not necessarily just for simplicity, but for a lot of reasons. And then other people like to micro divide the nucleus into multiple names. And of course, people used to be able to name different brain structures after themselves. So there'd be the nucleus of Lex and then, you know, and the Huberman fasciculus or whatever. Less of that nowadays, but, and by the way, those structures don't actually exist just yet. We haven't defined those yet, that I was making those names up.

• 1:27:46Andrew D. Huberman?

  But what's interesting is it seems like in the last five years, there's been a lot of, there's been a trend, excuse me, toward a requirement for lumping. Like you can't say, it seems that it's not allowed, if you will, to say, hey, yeah, you know, and here I'm not stating my, I will never reveal my preferences about pandemic related things for hopefully obvious reasons. It, you know, some people will say vaccines, yes, but masks, no. Or vaccines and masks, yes, but let people work. And other people will say, no, everyone stay home. And then other people will say, no, you know, no vaccines, no masks, let everybody work. No one was saying no vaccines, no masks and, and stay home, I don't think. So there's this sort of.

• 1:28:33Andrew D. Huberman?

  Lumping, right, the the boundaries around ideology really did start to defy science. I mean, it wasn't scientific. It was one part science ish at times and sometimes really hardcore science. Other times it was politics, economics. I mean, we really saw the confluence of all these different domains of society that use very different criteria to evaluate the world. I mean, I, as a scientist, you know, I remember when the vaccines first came out and I, I asked somebody, you know, one of the, the early concerns I had that was actually satisfied for me was how does this thing turn off? You know, if you start generating mRNA, how does it actually get turned off? So I asked a friend, you know, they know a lot about RNA biology and said, you know, how's it turn off? They explained

• 1:29:18Andrew D. Huberman?

  it to me. I was like, okay, makes sense. I asked some other questions. So, but, most people aren't going to think about it at that level of detail necessarily. But it did seem that there was just kind of amorphous blobs of ideology that, that grabbed on to things. And then there was this need for a chasm between them. There, it was almost felt like it became illegal in some ways to want, you know, two of the things from that menu and one of the things from that menu. I really felt like I was being constrained by a kind of like bento box model where I didn't get to define what was in the bento box. I could either have bento box A or bento box Z, but nothing in between.

• 1:29:59Lex Fridman?

  And I think on that topic, and I think a lot of topics, most people are in the middle with humility, uncertainty, and they're just kind of trying to figure it out. And I think there is just the extremes defining the nature of this division. So I think it's the role of a lot of us in our individual lives. And also, if you're, if you have a platform of any kind, I think you have to try to walk in the middle, like with empathy and humility. And that's actually what science is about is the, is the, is the humility. I'm still thinking about who's the opposite of Trump. I, it.

• 1:30:33Andrew D. Huberman?

  Well, maybe it is not. I mean, maybe Fauci is orthogonal to, to Trump. I mean, I, not everything has an opposite. I mean, it's, you know, maybe he's an N of one. Maybe he's in the minority of one because he was an outsider and from Washington who then made it there.

• 1:30:48Lex Fridman?

  But also, I wonder.

• 1:30:52Lex Fridman?

  You know, you have to pick your battles because every battle you fight, you should take very seriously. And just the amount of hate I get, I got, and I still get for having sat down with the Pfizer CEO. That was a very valuable lesson for me.

• 1:31:06Andrew D. Huberman?

  Well, that one was, got you a lot of heat?

• 1:31:09Lex Fridman?

  Yeah, it still does. Because

• 1:31:11Andrew D. Huberman?

  Cause you had some, some pretty controversial guests on.

• 1:31:14Lex Fridman?

  Yeah, but that one, that one, um.

• 1:31:17Andrew D. Huberman?

  Is he still the Pfizer CEO?

• 1:31:18Lex Fridman?

  I believe so.

• 1:31:20Andrew D. Huberman?

  CEOs turn over like crazy. This is the thing I didn't realize, you know, in, in science, if somebody moves institutions like a big deal, most people don't have more than two moves in their, in their career, maybe, but they often, you know, move to the next building is a big deal. But it, in biotech, it's like, I, I have a former colleague of mine from San Diego, and he's been CEO here, then he's a CEO there. He's, he went back to a company he was a CEO at before, you know, but he's probably back at the university he worked at for, for all I know. It's amazing how much moving around there is, is a very itinerant profession.

• 1:31:49Lex Fridman?

  Yeah, I think there, in certain companies, I guess in biotech would be the case, the, the CEO is more of like a, a manager type, so you can, someone's jumping around benefits your experience, so you get, become better and better at being a manager. There's some like leader revolutionary CEOs that stick around for longer because they're so critical to pivoting a company, like the Microsoft CEO currently, uh, Sundar Pichai, somebody like that, uh, obviously Elon Musk is somebody like that, that is part of pivoting a company into new domains constantly. But yeah, in biotech, there's a machine.

• 1:32:26Lex Fridman?

  And for, you know, in the eyes of a lot of people, uh, big pharma is like big tobacco. It's, um, it's the epitome of everything that is wrong with capitalism. It's, uh, it's evil, right? And so I showed up in the conversation where I thought with a pretty open mind and really asked. What I thought were difficult questions of him. I don't think he's ever sat down to a grilling of that kind. In fact, I'm pretty sure they cut the interview short because of that. And I thought, you know, literally it was hot in the room and we're sweating. And I was asking tough questions for, for somebody that like half the country or a large percent of the country believes he's alleviated a lot of,

• 1:33:11Lex Fridman?

  he helped through the financial resources that, that Pfizer has, helped alleviate a lot of suffering in the world. And so I thought for somebody like that, I was asking pretty hard questions. Boy, did I get to hear from the side. Usually one of the sides is more intense in their anger. So there's certain political topics like with, with Andrew Tate, for example, I would, I would hear from a very, it would probably be the left, far left that would write very angrily. And so that's a group you hear from.

• 1:33:53Lex Fridman?

  The Pfizer CEO, I didn't get almost any messages from people saying, why did you go so hard on, on him? You know, he's a, he's an incredible human, incredible leader and CEO of a company that helped, helped us with the vaccine that nobody thought would be possible to develop so quickly.

• 1:34:12Andrew D. Huberman?

  You did not get letters of that sort?

• 1:34:13Lex Fridman?

  I did not. I mean, like here and there, but the, the sea of people that said everything from me being weak, that I wasn't able to call out this person. How do you sit down? How do you platform this evil person? How do you make him look human? All that kind of stuff. And that you have to deal with that. You have to, of course, it's great. It's great because I have to do some soul searching, which is like, did I? Like you have to ask some hard questions. I love criticism like that. You, you get to like, you know, I hit some low points. There's definitely some despair and you start to wonder like, was I too weak? Should I have talked to him? What is true?

• 1:34:55Lex Fridman?

  And you sit there alone and just like marinate in that. And hopefully over time that makes you better. But I still don't know what the right answer with that one is.

• 1:35:02Andrew D. Huberman?

  Well, I feel that money plays a role here. You know, when people think big pharma, they think billions of dollars, maybe even trillions of dollars, really. And certainly, people who make a lot of money get scrutiny that others don't. Part of it is that they are often not always visible. But I think that there is a natural and reflexive, and I'm not justifying it. I certainly don't feel this because I do. I know some people who are very wealthy, some people who are very poor. I can't say it scales with happiness at all.

• 1:35:44Andrew D. Huberman?

  People are always shocked to hear that, but it, you know, but that's what I've observed in very wealthy people. But that people who have a lot of money are often held to a different standard because people resent that, some people resent that, and maybe there are other reasons as well. I mean, among people who are very wealthy, oftentimes the wish is for status, right? Not money. You get a bunch of billionaires in a room, and unless one of them is Elon, who is also has immense status for his accomplishments. Typically, if you put a Nobel Prize winner in a room with a bunch of billionaires, they're all talking to that person, right? And there are many very interesting billionaires.

• 1:36:29Andrew D. Huberman?

  But status is, is something that is often, but not always associated with money, but is a much rarer form of uniqueness out there, a positive uniqueness. If one considers status positive, because there's a downside too. But. So I wonder whether or not the Pfizer CEO caught extra heat because people assume, and I probably assume also, that his salary is quite immense.

• 1:36:58Lex Fridman?

  Yeah, so because I have a lot of data on this, I can answer, it's a very good hypothesis. Let's test it scientifically.

• 1:37:04Andrew D. Huberman?

  He's about to tell me it's a great hypothesis, but it's wrong. I know this smirk.

• 1:37:09Lex Fridman?

  I honestly think it's wrong. There is, that effect is there for a lot of people, but I think the distrust is not towards the CEO, the distrust is towards the company. One of the really difficult soul searching I had to do, which is just having interact with Pfizer folks at every level, from junior to CEO, they're all really nice people. They have a mission, they talk about trying to really help people, because that's the best way to make money, is come up with medicine that helps a lot of people. The mission is clear, they're all good people, a lot of really brilliant people, PhDs. So you can have a system where all the people are good, including the CEO, and by good,

• 1:37:52Lex Fridman?

  I mean people that really are trying to do everything, they dedicate their whole life to do good. And yet, you have to think that that system can deviate from a path that does good, because you start to deceive yourself of what is good, you turn it into a game, where money does come into play from a company perspective, where you convince yourself, the more money you make, the more good you'll be able to do, and then you start to focus more and more and more on making more money, and then you can really deviate and lose track of what is actually good. I'm not saying necessarily Pfizer does that, but I think companies could do that.

• 1:38:33Lex Fridman?

  You can apply that criticism to social media companies, to Big Pharma companies, that one of the big lessons for me, that's I don't know what the answer is, but that all the people inside a company can be good. People you would want to hang out with, people you'd want to work with, but as a company is doing evil. And like, that's a possibility. So like, the distrust, I don't think is towards the billionaire individual, which I do see a lot of. In this case, I think it's, it's like Wall Street distrust, that the machinery of this particular organization has gone off track.

• 1:39:10Andrew D. Huberman?

  It's the generalization of hate again.

• 1:39:12Lex Fridman?

  Yeah. And then, good luck figuring out what is true. This is the, this is the tough stuff. But I should say, the individuals, like individual scientists at the NIH, in Pfizer, are just incredible people. Like, they're, they're really, they're really brilliant people. So the, you know, I never trust the administration or the business people, no offense, business people, but the scientists are always good. They, they have the right motivator in life. But again, with, they can have blinders on to focus on the science. Nazi Germany has a history of people just too focused on the science. And then the politicians use the scientists to achieve whatever and they want.

• 1:39:56Lex Fridman?

  But if you just look narrowly at the, the journey of a scientist, it's a beautiful one, because they ultimately in it for the curiosity, the moment of discovery versus money. Whereas, I mean, prestige probably does come into play later and later in life, but especially young scientists, they're after the, it's like they're pulling at the thread of curiosity to try to discover something big. They get excited by that kind of stuff, and it's beautiful to see.

• 1:40:24Andrew D. Huberman?

  It is beautiful. See, I have a former graduate who now a postdoc at Caltech, and I don't even know if she had a cellphone. She would come into lab, put her cellphone into the desk, and she was tremendously productive. But that, that wasn't why I brought it up. She was productive as a side effect of just being absolutely committed and obsessed to discover the answers to the questions she was asking as best she could. And it was, you could feel it. You just feel the intensity and just incredibly low activation energy. If there was an experiment to do, she would just go do it. You're teaching at MIT, you are

• 1:41:00Andrew D. Huberman?

  Obviously, traveling the world, you're writing the podcast, a lot of coverage of chess recently, which is interesting. I don't play chess, but I

• 1:41:07Lex Fridman?

  Oh, I have some scientific questions to you about that.

• 1:41:09Andrew D. Huberman?

  Oh, okay, sure. And then, um, let's get to those for sure. And then

• 1:41:13Lex Fridman?

  You're not gonna like it.

• 1:41:14Andrew D. Huberman?

  Oh, no. Okay. And then, and then also some, some very, um, do I have to spell Massachusetts again? The, also, you still seem to have a proclivity for finding guests that are controversial, right? You're thinking about Tate, we're talking about Trump, we're talking about the Pfizer CEO, we're talking about Fauci. These are, these are in intense people. And so what we're getting, folks, is a, um, we're not doing neuroimaging here in the traditional sense of putting someone into a scanner. What we're doing here is we're using as the great Carl Diceroff, who was on your podcast.

• 1:41:46Lex Fridman?

  Thank you for that. Thank you for connecting us. He's an incredible person.

• 1:41:49Andrew D. Huberman?

  He's an incredible psychiatrist, bioengineer, and human being, and, and writer, and your conversation with him was phenomenal. I, I listened to it twice. I actually have taken notes. Um, we talk about it in this household. We really do. His, uh, his description of love is not to be missed. I'll just leave it at that, because if I try and say it, I won't capture it. Well, but you know, we're getting a, a language-based, um, map of, uh, at least a portion of Lex Fridman's brain here. So, um, what else is going on these days in that brain as it relates to robotics, AI? Our last conversation was a lot about

• 1:42:30Andrew D. Huberman?

  robots and the potential for robot-human interaction, what even what is a robot, et cetera? Are you still working on robots or focused on robots? And, you know, where, where is science showing up in your life besides the things we've already talked about?

• 1:42:43Lex Fridman?

  So I think the last time we talked was before Ukraine.

• 1:42:46Andrew D. Huberman?

  Yes. You were just about to leave.

• 1:42:50Lex Fridman?

  Yes. So that, I mean,

• 1:42:51Andrew D. Huberman?

  So that's why I went on. I was like, you know, this might be the last. You said you want to come out here before or after? I was like, I'll come out there before. I want to see you before you go. But here you are, in the flesh.

• 1:43:01Lex Fridman?

  I think, uh, so a lot of, um, just a lot of my mind has been occupied, obviously, with that part of the world. But the, the most of the difficult struggles that I'm still going through is that I haven't launched a company that I want to launch. And the company has to do with AI. I mean, it's maybe a longer conversation, but the ultimate dream is to put robots in every home. But short-term,

• 1:43:28Lex Fridman?

  I see their possibility of launching a social media company. And the it's a non trivial explanation why that leads to robots in the home. But it's basically the algorithms that fuel effective social robotics. So robots that you can form a deep connection with. And so I've been really, yeah, I've been building prototypes. But struggling that I don't have. Maybe if I were to be critical, the guts to to launch a company.

• 1:44:00Andrew D. Huberman?

  Or the time.

• 1:44:01Lex Fridman?

  Well, it's combined.

• 1:44:02Andrew D. Huberman?

  I think you've got the guts. I mean, it's clear if you'll do an interview with the Pfizer CEO and you're considering putting this Tate fellow on your podcast and you've gone to the Ukraine. That you you have the guts. I don't it's also a it means not doing quite a lot of other things.

• 1:44:18Lex Fridman?

  That's what I mean, but it does takes. The thing is, as many people know, when you fill your day and you're busy. That busyness becomes an excuse that you use against doing the things that scare you. A lot of people use family in this way. You know, my wife, my kids, I can't. When in reality, some of the most successful people have a wife and have kids and have families and they still do it. And so a lot of times we can fill the day with busy work with like. Like, yeah, of course I have podcasts and all this kind of stuff and they make me happy and they're all they're wonderful and.

• 1:44:59Lex Fridman?

  There's research, there's teaching and so on, but all of that can just serve as an excuse from the thing that my heart says is the right thing to do. And that's why I don't have the guts, the guts to say no to basically everything. And then to focus all out because part of it is. I'm unlikely to fail at anything in my life currently because I've already found a comfortable place. With with a startup, it's mostly going to be most likely going to be a failure, if not an embarrassing failure. So well, the machine learning data that I'm aware of.

• 1:45:34Andrew D. Huberman?

  I don't know a lot about machine learning, but the within the realm of neuroscience say that a failure rate of about 15% is optimal for neuroplasticity and growth. Whether or not that translates to all kinds of practices isn't clear, but getting trials right 85% of the time seems to be optimal for language learning, seems to be optimal for mathematics and seems to be optimal for physical pursuits on average, right? I'm sure I'm gonna, you know, that you know, you have more machine learning geeks that listen to your podcast than listen to this podcast, but doesn't mean you have to fail on 15% of your weight sets, folks. I mean, it could be, you know, 16%. No, I'm just kidding. But the it's it's not exact, but it but it's a pretty good rule of thumb.

• 1:46:19Lex Fridman?

  I think a lot of startup founders would literally murder for 85% chance of success. I think I think, given all the opportunities I have, the the skill set, the the funding, all that kind of stuff, my chances are relatively high for success. But what relatively high means in the startup world is still far, far below 85. It's we are talking about single digit percentages. Most startups fail.

• 1:46:47Andrew D. Huberman?

  Well, I think it means, you know, the decision to focus on the company and not other things means the decision to close the hatch on dopamine retrieval from all these other things that are very predictable sources of dopamine. Not that everything is dopamine, but you know, dopamine is, I think, the the primary chemical driver of motivation. You know, if you know that you can get some degree of satisfaction from scrolling social media or from that particular cup of coffee, that's what you're gonna do. That's what you're going to consume unless you somehow invert the algorithm and you and you say, you know, it's actually my denial of myself drinking that coffee that's gonna be the the dopamine, right?

• 1:47:27Lex Fridman?

  Interesting.

• 1:47:27Andrew D. Huberman?

  Then, you know, and that's the beauty of having a forebrain is that you can make those decisions. You know, this is the essence, I do believe, of what we see of David Goggins. There's much more there. There's a person that none of us know and only he knows, of course, but. The idea that the pain is the source of dopamine, the limbic friction, as I sometimes like to call it, is the source of dopamine, that runs counter to how most nervous systems work. But it was, it's decision based, right? It's not because his musculature is a certain way, or his, you know, he had CRISPR or something. It's because he decides that. And I, I think that's amazing, but what it means in terms of starting a company and changing

• 1:48:08Andrew D. Huberman?

  priorities is a, closing the hatch on all or many of the current sources of dopamine so that you can derive dopamine from the failures within this narrow context. And this is a very reductionist view, a kind of neuro centric view of what we're talking about. But I think about this a lot. I mean, the decision to choose one relationship versus another is a decision to close down other opportunities, right? So I think that the, you know, the, the decision to order one thing off the menu versus others is this decision to close down those other hatches. So I think that you absolutely can do it. It's just a question of, can you flip the algorithm?

• 1:48:47Lex Fridman?

  Yeah, remap the source of dopamine to something else.

• 1:48:51Andrew D. Huberman?

  That's right. And maybe, and maybe go out there not to succeed, but make the, you know, the journey is the destination type thing. But, you know, when you're financially vested and your time, and as far as I know, we only get one life, at least on this planet, and you want to spend that wisely, right?

• 1:49:08Lex Fridman?

  And a lot of the, the people that surround you, I mean, people are really important. And I don't have people around me that say you should do a startup. It's very difficult to find such people.

• 1:49:25Andrew D. Huberman?

  Is Austin big startup culture right now?

• 1:49:26Lex Fridman?

  Yeah, it is, it is. But it doesn't make sense for me to do a startup. This is what, the people that love me, my whole life have been telling me, it doesn't make sense what you're, what you're doing right now. Just do the thing you were doing previously.

• 1:49:37Andrew D. Huberman?

  Why do I get the sense that because they are saying this, you're apt to go against them?

• 1:49:41Lex Fridman?

  No, actually, I was never that unfortunate. Unfortunately, I need I've talked to people I love, my parents, family and so on, friends. I'm one of those people that needs unconditional support for difficult things. Like I know myself coaching wise, it's good to, I like, so here's how I get coached best. Let's say wrestling. I like a coach that says, you want to win the Olympics? They will not first, if I say I want to win the gold medal at the Olympics in freestyle wrestling. I, I want a coach that doesn't blink once and hears me and believes that I can do it.

• 1:50:21Lex Fridman?

  And then is viciously intense and cruel to me on the, on, on that pursuit. Like if you want to do this, let's do this. All right, so, but that's support. That like that positivity, I don't, I'm never, you know, I'm not energized. Nor do I see that as love, a person saying like, basically criticizing that. Like saying like, you're, you're too old to win the Olympic gold medal, right? You're like all the things you can come up with. That's not helpful to me and I can't find a dopamine or I haven't yet a dopamine source from the, the haters.

• 1:51:03Lex Fridman?

  Like basically people that are criticizing you, you're just trying to prove them wrong. It doesn't, it never got me off, like it never.

• 1:51:12Andrew D. Huberman?

  Where some people seem to like that. I mean, David Goggins always seems to come out, he seems driven by many sources that he has access. I do, I don't know because I've never asked him, but I, I, if I were to venture a guess, I'd say that he probably has a lot of options inside his head as to how to push through challenge, not just overcome pain, not, but, but he'll post sometimes about the fact that, you know, people will say this or people will do this and, you know, it's, and, and talk about the pushback approach. He'll also talk about the pushback approach that's purely internal, that doesn't involve anyone else. Great versatility there.

• 1:51:48Lex Fridman?

  Yeah, there's a, there's literally like a voice he yells at that represents some kind of like devil that wants him to fail and he's.

• 1:51:58Lex Fridman?

  You know, he calls him bitch and all kinds of things saying, you know, fuck you. I'm not, I'm not. He's, there's always like an enemy and he's going against that enemy. And I wish, maybe that's something, I mean, it's really interesting. Maybe you can remap it this way so that you can construct, like that's a kind of obvious mechanism. Construct an amorphous blob that is a hater that wants you to fail. Right? That's kind of the David Goggins thing. You're in that, that, that blob says, you're too weak. You're too dumb. You're, you're too old. You're too fat. You're too whatever. And getting you to want to quit and so on. And then you start getting angry at that blob. And maybe that's a good motivator. I haven't personally really tried that.

• 1:52:42Andrew D. Huberman?

  Well, I've had external, you know, challenge when I was a postdoc, a very prominent laboratory, several prominent laboratories, in fact, were working on the same thing that I was and I was just slowly postdoc, working on a project pretty independent from the lab I was in. And there was competition, but there was plenty of room for everybody to win. But in my head, and frankly, I won't disclose who this is. And, and because there was some legitimate competition there and a little bit of friction, not, not too much, healthy scientific friction. Yeah, I might've pushed a few extra hours or more, a little bit. I have to say, it felt metabolizing. It felt catabolic, right? It didn't, I couldn't be sustained by it.

• 1:53:27Andrew D. Huberman?

  And I contrast that with the podcast or the work that my laboratory is doing now, focused on stress and human performance, et cetera. And it's pure love. I just, I want, it's pure curiosity and love. I mean, they're hard days, but I never, there's no adversary in the picture. They're the practical, you know, workings of life that.

• 1:53:47Lex Fridman?

  Well, those are the things that Joe really inspired me on. And people do create adversarial relationships in podcasting. Cause you get, like YouTubers do this, they get, you know, they hate seeing somebody else be successful. There's a feeling of like.

• 1:54:03Lex Fridman?

  Like jealousy and some people even see that as healthy like, oh, this like Mr. Beast or somebody, some of these popular YouTubers, oh, how do they get 100 million views and I only get 20 views?

• 1:54:16Andrew D. Huberman?

  Like Mr. Beast devoted his entire, according to him, his entire life, he's been focused on becoming this massive YouTube channel.

• 1:54:22Lex Fridman?

  Yeah, well, that, you know, he's inspiring in many ways, but like there's some people that get become famous for doing much less insane pursuit of greatness than Mr. Beast. Like this, people become famous on, you know, on social media and so on, and it's easy to be jealous of them. I just, one of the early things I've learned from Joe, just being a fan of his podcast is how much he celebrated everybody. And again, I guess, maybe I ruined my whole dopamine thing, but I don't get energized by people that are, that become popular. In the podcasting space and YouTube, it doesn't, it's awesome. It's all of it is awesome and I'm inspired by that. But the problem is that's not a good motivator. Inspiration is like, oh, cool, humans can do this.

• 1:55:06Lex Fridman?

  This is beautiful, but it's not, I'm looking, I'm looking, you know, for, for forcing function. That's why I gave away the salary from MIT. I was hoping my bank account had zero, that would be a forcing function to be like, oh shit. And I, you know, and you're not allowed to have a normal job. So I wanted to launch and then the podcast becomes, you know, a source of income. And so it's like, god damn it.

• 1:55:29Andrew D. Huberman?

  Yeah, well, you know, and here I, I have to confess my biases. You are, you are so good at what you do in the realm of podcast and you're excellent at other things as well. I just have less, you know, experience in those things. I know here I'm, I'm taking the liberty of speaking for many, many people and just saying I, I sure as.

• 1:55:54Andrew D. Huberman?

  Hell, hope you don't shut down the podcast, but as your friend and as somebody who cares very deeply about your happiness and your deeper satisfaction, if it's in your heart's heart to do a company, well, then, damn it, do the company.

• 1:56:10Lex Fridman?

  And a lot of it, I wouldn't even characterize as happiness. I don't know if you have things like that in your, in your life, but I'm probably the happiest I could possibly be right now.

• 1:56:21Andrew D. Huberman?

  That's wonderful.

• 1:56:22Lex Fridman?

  But the thing is, there's a longing for the startup that has nothing to do with happiness. It's something else.

• 1:56:28Andrew D. Huberman?

  That's that itch.

• 1:56:29Lex Fridman?

  I'm pretty sure I'll be less happy because it's a really tough process. It's, I mean, to whatever degree you can extract happiness from struggle, yes, maybe, but I don't see it. I think I'll have some very, very low points. There's a lot of people who find companies, found companies, know about your, and I also want to be in a relationship. I want to get married and sure as hell, a startup is not going to increase the likelihood of that.

• 1:57:00Andrew D. Huberman?

  We could start up a family and start a company.

• 1:57:03Lex Fridman?

  Well, that, that's, I'm a huge believer in that, which is getting in a relationship at a low point in your life, which is.

• 1:57:13Andrew D. Huberman?

  Sorry, I'm not disputing your stance, nor am I agreeing with it. It's just, every once in a while, there's a, there's a Lex Fridman-ism that, that hits a particular circuit in my brain. I had to just laugh out loud.

• 1:57:26Lex Fridman?

  I just think that it's easy to have a relationship when everything is good. The relationships that become strong and are tested quickly are the ones when, when shit is going down.

• 1:57:38Andrew D. Huberman?

  Well, then there's hope for me yet.

• 1:57:42Andrew D. Huberman?

  So, you know, before we sat down, I was having a conversation with a podcast producer who is a, I wouldn't say avid, rather, he's a rabid consumer of podcasts and finds these amazing podcasts. He's small podcasts and, you know, and, and unique episodes. Anyway, we were talking about some stuff that he had seen and read in the business sector, and he was talking about the difference between, you know, job, career, and a calling, right? And I, and I think he was extracting this from conversations of, of. CEOs and founders, et cetera. I forget the specific founders that that brought this to light for him.

• 1:58:25Andrew D. Huberman?

  But you know that this idea that if you focus on a job, you know, you can make an income and hopefully you enjoy your job or not hate it too much. A career is represents a sort of, in my mind, a kind of series of evolutions that one can go through, junior professor tenure, et cetera. But a calling has a whole other level of energetic pull to it because it includes career and job and includes this concept of sort of like a life. It's very hard to draw the line between a calling in career and a calling in the other parts of your life. So the question therefore is, do you feel a calling to start this company? Or is it born of a compulsion that irritates you?

• 1:59:09Andrew D. Huberman?

  Is it like something you wish would go away? Or is it something that you that you hope will won't go away?

• 1:59:14Lex Fridman?

  No, I hope it won't go away. It's a calling. It's a calling.

• 1:59:17Andrew D. Huberman?

  That's beautiful.

• 1:59:18Lex Fridman?

  It's like, when I see a robot, when I first interacted with robots and it became even stronger, the most sophisticated the robots I interacted with, I see a magic there. And you're like, you look around, does anyone else see this magic? Like, it's it's kind of like, maybe when you fall in love, like, that that feeling like, does anyone else notice this person? I just walk in the room, I feel that way about robots. And I can elaborate what that means, but I'm not even sure I can convert it into words.

• 1:59:55Lex Fridman?

  I just feel like the social integration of robots in society will create a really interesting world. And our ability to anthropomorphize when we look at a robot and our ability to feel things when we look at a robot is something that most of us don't yet experience, but I think everybody will experience in the next few decades. And I I just want to be a part of that of exploring that because it hasn't been really thoroughly explored. The best roboticists in the world are not currently working on that problem at all. They they try to avoid human beings completely. And nobody's really working on that problem in terms of when you look at the numbers.

• 2:00:38Lex Fridman?

  All the big tech companies that are investing money, the closest thing to that is Alexa and. Basically being a servant to help to tell you the weather, play music and so on. It's not trying to form a deep connection. And so I, I, sometimes you just notice the thing. Not, not only do I notice the magic. There's a gut feeling, which I try not to speak to because there's no track record. But I feel like I can be good at bringing that magic out of the robot. And there's no data that says I would be good at that. But there's a feeling, it's just a feeling. Like I, you know, when I, because I've done so many things.

• 2:01:22Lex Fridman?

  I love doing, playing guitar, all that kind of stuff. Jiu Jitsu, I've never felt that feeling. When I'm doing jiu jitsu, I don't feel the, the magic of the genius required to be extremely good. At guitar, I don't feel any of that. But I've noticed it in others. Great musicians, they will, they, they notice the magic about the thing they do. And they, and they rattle it. And I just always thought, um, I think it had a different form when I, before I knew robots existed, before AI existed, the, the form was, um,

• 2:01:58Lex Fridman?

  more about the magic between humans. The, like, I, I think of it as love, but like the smile the two friends have towards each other. When I was really young and people would be excited when they first know each other and see, notice each other. And there's that moment that they share that feeling together. And I was like, wow, that's really interesting. It is, it is really interesting that these two separate intelligent organisms are able to connect all of a sudden on this deep emotional level. It's like, huh. It's, it's, it's just beautiful to see and I noticed the magic of that. And then when I started, uh, programming, programming period, but then programming AI systems,

• 2:02:42Lex Fridman?

  you realize, oh, that could be, that's not just between humans and humans. That could be humans and other entities, dogs, um, cats and robots. And that's so I, for some reason, it hit me the most intensely when I saw robots. And so, yeah, it's, it's like a calling. But it's a calling that I, I can just enjoy.

• 2:03:06Lex Fridman?

  The uh, the vision of it, the vision of a future world, of an exciting future world that's full of cool stuff, or I can be part of building that. And being part of building that means doing a hard work of capitalism, which is like raising funds from people, uh, which for me right now is the easy part. And then hiring a lot of people. I don't know how much you know about hiring, but hiring-

• 2:03:32Andrew D. Huberman?

  Hiring excellent people.

• 2:03:33Lex Fridman?

  Excellent people.

• 2:03:34Andrew D. Huberman?

  Yeah.

• 2:03:35Lex Fridman?

  That will define the trajectory of not only your company, but your whole existence as a human being. And, and building it up, not failing them, because now they all depend on you, and not failing the world with an opportunity to bring something, something that brings joy to people. And like all that pressure, just non-stop fires that you have to put out, the drama, the having to work with people you've never worked with, like lawyers and the human resources and supply chain and, and uh, you know, like, because this is very compute-heavy, the compute infrastructure, managing, security, cybersecurity is because you're dealing with people's data.

• 2:04:17Lex Fridman?

  So now you have to understand not only the, uh, the cybersecurity of data and the privacy, how to maintain privacy correctly with data, but also the psychology of people trusting you with their data. And what is, how, how, you know, if you look at Mark Zuckerberg and Jack Dorsey and those folks, they seem to be hated by a large number of people.

• 2:04:37Andrew D. Huberman?

  Jack seemed, I didn't, you know, I didn't-

• 2:04:40Lex Fridman?

  Much less so, yes.

• 2:04:41Andrew D. Huberman?

  I think, I always think of Jack as a, as a loved individual, but um-

• 2:04:45Lex Fridman?

  Well, you have a very positive view of the world, yes.

• 2:04:48Andrew D. Huberman?

  I like Jack a lot and I, I like his mind and I, um, someone close to him described him to me recently as, he's an excellent listener. That's what they said about Jack and that, that's my experience of him too. A very private person, so we'll, we'll leave it at that, but um, uh- Listen, I think Jack Dorsey is one of the, one of the greats of our, of the last 200 years. And is just much quieter about his stance on things than a lot of people. But much of what we see in the world that's wonderful, I think we owe him a debt of gratitude. I'm just voicing my stance here, but.

• 2:05:26Lex Fridman?

  And the person, this is really important.

• 2:05:28Andrew D. Huberman?

  Yeah.

• 2:05:29Lex Fridman?

  A wonderful person, a brilliant person, a good person. But you still have to pay the price of making any kind of mistakes as the head of a company. You don't get any extra bonus points for being a good person.

• 2:05:45Andrew D. Huberman?

  But his willingness to go on Rogan and deal directly and say, I don't know, an answer to that in some cases, but to deal directly with some really challenging questions, to me earned him tremendous respect.

• 2:05:58Lex Fridman?

  Yes, as an individual, he was still part of them is, so you, you've said, and I love Jack too, and I interact with him.

• 2:06:06Andrew D. Huberman?

  Yeah, he's been on your podcast.

• 2:06:07Lex Fridman?

  Yes, but he's also part of a system, as we talked about. And I would argue that Jack shouldn't have brought anyone else with him on that podcast.

• 2:06:18Andrew D. Huberman?

  Oh, that's right. He had a cadre of.

• 2:06:20Lex Fridman?

  Oh, he had, I guess, the legal, the head legal with him. And also it requires a tremendous amount of skill to go on a podcast like Joe Rogan and be able to win over the trust of people by being able to be transparent and communicate how the company really works. Because the more you reveal about how a social media company works, the more you open up for security, the vector of attacks increases. Also, there's a lot of difficult decisions in terms of censorship and not that are made, that if you make them transparent, you're going to get an order of magnitude more hate. So you have to make all those kinds of decisions.

• 2:06:58Lex Fridman?

  And I think that's one of the things I have to realize is you have to take the, that avalanche of.

• 2:07:09Lex Fridman?

  Potentially hate if you make mistakes.

• 2:07:13Andrew D. Huberman?

  Well, you you have a very clear picture of this architecture of what's required in order to create a company. Of course, there's division of labor, too. I mean, you don't have to do all of those things in detail, but finding people that are excellent to do, you know, to run the critical segments are is obviously key. I'll just say what I said earlier, which is if it's in your heart's heart to start a company, if that indeed is your calling, and it sounds like it is, then I can't wait.

• 2:07:45Lex Fridman?

  Does the heart have a heart? I don't know. What's that expression even mean?

• 2:07:48Andrew D. Huberman?

  Probably not. In my lab, at one point, early days, we worked on cuttlefish, and they have multiple hearts, and they but they pump green blood, believe it or not, a very fascinating animal. Speaking of hearts and green blood, earlier today, before we sat down, I solicited for questions on Instagram in a brief post. So.

• 2:08:11Lex Fridman?

  You want to look at some of them?

• 2:08:13Andrew D. Huberman?

  Yes, let's take these in real time. My podcast team is always teasing me that I never have any charge on my phone. I'm one of these people that likes to run in the run in the yellow or wherever it is.

• 2:08:26Lex Fridman?

  An iPhone?

• 2:08:27Andrew D. Huberman?

  Yeah.

• 2:08:27Lex Fridman?

  It's funny how always the iPhone people are out of battery.

• 2:08:30Andrew D. Huberman?

  Well, I just got a new one. I mean, this one has plenty of battery. I just got a new one. So I have different numbers for different things, personal and work, etc. I'm trying that now. All right, get into the.

• 2:08:45Lex Fridman?

  I have a I have a chess thing, too, to mention to you.

• 2:08:48Andrew D. Huberman?

  Oh, yes, please. Will I insult you if I if I look up these questions as you ask me?

• 2:08:52Lex Fridman?

  No, no, but I will insult you by asking this question because I think it's hilarious. So there's been a controversy about cheating, where Hans Niemann, who's a 2700 player.

• 2:09:02Andrew D. Huberman?

  Oh, yeah, I saw that clip on your Clips channel. By the way, I love your Clips channel, but I listen to your full channel.

• 2:09:08Lex Fridman?

  The big accusation is that he cheated by having, I mean, it's half joke, but it's starting getting me to wonder whether.

• 2:09:17Lex Fridman?

  So that you can cheat by having vibrating anal beads. So you can send messages to uh.

• 2:09:24Andrew D. Huberman?

  Well, let's rephrase that statement. Not you can, but one can.

• 2:09:29Lex Fridman?

  One can, one can.

• 2:09:30Andrew D. Huberman?

  Thank you.

• 2:09:30Lex Fridman?

  That was a personal attack, yes. But it made me realize, I mean.

• 2:09:34Andrew D. Huberman?

  I'm just gonna adjust myself.

• 2:09:35Lex Fridman?

  Excited here. Um, I use it all the time for podcasts and send myself messages to remind me myself of notes. Uh, but it's interesting, I mean, it, um.

• 2:09:46Andrew D. Huberman?

  I'm not gonna call you again.

• 2:09:49Lex Fridman?

  Yeah, that's exactly where I keep my phone. The, the, it did get me down this whole rabbit hole of, well, how would you be able to send communication?

• 2:10:00Lex Fridman?

  In order to cheat in different sports? I mean, that doesn't even have to do with um chess in particular, but it's interesting in chess and poker that there is um. There's mechanisms sort of modern day where you're streaming live the competition. So people can watch it on TV. If they can only send you a signal back.

• 2:10:22Lex Fridman?

  They, you know, it's, it's just like a fun little thing to think about. And if it's possible to pull off. So I wanted to get your scientific uh evaluation of that technique.

• 2:10:33Andrew D. Huberman?

  To cheat using some sort of interoceptive device.

• 2:10:36Lex Fridman?

  Yeah, vibrating of some kind, yeah. Well, no, no, that's one way to send signals is like Morse code, basically.

• 2:10:42Andrew D. Huberman?

  Yeah, so there's a famous. I believe there's a famous real world story of physics students. I'm gonna get some of this wrong, so I'm saying this um in kind of a course form so that somebody will correct this. But um, I believe it was physics graduate students from UC Santa Cruz or somewhere else. Maybe it was Caltech, a bunch of universities so that no one, you know, associates with any one university that went to Vegas and used some sort of tactile device for kind of um card counting um thing. This was actually um. demonstrate also, not this particular incident, I don't think, in the movie Casino,

• 2:11:24Andrew D. Huberman?

  where there was, they, where they spotted a, I remember Robert De Niro, who you, you have a not-so-veg resemblance to, by the way, in Taxi Driver.

• 2:11:33Lex Fridman?

  God, I wish I had a De Niro impression right now.

• 2:11:37Andrew D. Huberman?

  Travis Bickle. Um, look it up, folks. Travis Bickle is, you know, um, if Lex ever shaved his head into a mohawk.

• 2:11:44Lex Fridman?

  I would.

• 2:11:45Andrew D. Huberman?

  So, they, he had a tapping device on his ankle that was signaling someone else was counting cards and then signaling to that person. So, yeah, that could be done in the tactile way. Um, it could be done, obviously, earpieces, if it's deep earpiece. I think that there are ways that they look for that. Um, certainly, any kind of vibrational device in whatever orifice, um, provided someone could pay attention to that while still playing the game. Um, yeah, I think it's, it's entirely possible. Now, could it be done purely neurally? You know, could there be something that was, um, and listen, it wouldn't have to even be below the skull. This is where, whenever people hear about Neuralink or brain-machine interface, they always think, oh, you have to drill down below the skull and put a chip below, into the skull. I think there are people walking around nowadays with, um, glucose monitoring devices,

• 2:12:29Andrew D. Huberman?

  like Levels, which I've used and it was very informative for me, actually, um, as a kind of an experiment. Gave me a lot of interesting insights about my blood sugar regulation, how it reacts to different foods, et cetera. Well, you know, you can implant a tactile device below the skin with a simple incision. Actually, one of the neurosurgeons at Neuralink I, I know well because he came up, um, at some point through my laboratory and was at Stanford, and he actually has put in a radio receiver in his hand and his wife has it too, and he can open locks and at, of his house and things like that, so he's been to-

• 2:13:01Lex Fridman?

  Under the skin?

• 2:13:02Andrew D. Huberman?

  Under the skin. You know, you can go to-

• 2:13:04Lex Fridman?

  How does that work? So, how do you-

• 2:13:05Andrew D. Huberman?

  A piercer. You go to a, you know, a, a body piercer-type person and they can just slide it under there and, and it's got a battery life of something and, you know, some fairly long duration.

• 2:13:15Lex Fridman?

  How do you experience the tactile, the, the haptics of it?

• 2:13:17Andrew D. Huberman?

  Oh, no, that just allows him to open certain locks with just his hand, but you could easily put some sort of tactile device in there.

• 2:13:24Lex Fridman?

  Um, but does that have to connect to the nerves or is it just like, just vibration?

• 2:13:29Andrew D. Huberman?

  No, just vibration and, you know-

• 2:13:30Lex Fridman?

  You can probably sense it, even if it's under the skin, I wonder?

• 2:13:32Andrew D. Huberman?

  And it can be by, and it can be Bluetooth-linked. I mean, you know, I've seen, there's a, a engineering laboratory at the University of Illinois, Champaign. Urbana that's got an amazing device, which is about the size of a Band-Aid. It goes on the clavicles and it uses sound waves pinged into the body to measure cavitation. Now, think about this for a moment. This is being used in the military where, let's say you're leading an operation or something. People are getting shot, shot at and on a laptop, you can see where the bullet entry points are. Are people dead? Are they bleeding out, you know, entry exit points? You can get, if, take it out of the battlefield scenario, you can get breathing, body position 24 hours a day. There's so much that you can do looking at cavitation.

• 2:14:15Andrew D. Huberman?

  So these same sorts of devices on 12-hour Bluetooth could be used to send all sorts of, maybe every time you're supposed to hold your hand, I'm not a good gambler. So I only play roulette when I go to Vegas because I just long boring and, you know, games where you get some good mileage out of each, out of each run usually. But the, you know, maybe every time you're supposed to hold, the person gets sort of like a stomach cinching because this is, you know, stimulating the vagus a little bit and they get a little bit of an, so it doesn't have to be Morse code. It can be yes, no, maybe.

• 2:14:49Lex Fridman?

  Yeah.

• 2:14:49Andrew D. Huberman?

  Right? It can be, you know, it can be a green, red, yellow type signaling. It doesn't have to be very sophisticated to give somebody a significant advantage. Anyway, I haven't thought about this in detail before this conversation, but oh yeah, there's an immense landscape.

• 2:15:03Lex Fridman?

  I don't know if you know a poker player named Phil Ivey?

• 2:15:06Andrew D. Huberman?

  No, I don't follow the gambling.

• 2:15:08Lex Fridman?

  Well, he's, he's considered to be one of the greatest poker players of all time, legitimately, you know, he's just incredibly good, but he got, there's this big case where he was accused of cheating and proven, and it's not really cheating, which is what's really fascinating is it turns out, so he plays poker, Texas Hold'em mostly, but all kinds of poker. It turns out that the, the grid on the back of the cards is often printed a little bit imperfectly.

  And so you can use the asymmetry of the imperfections to try to figure out certain cards. So if you play and you remember that a certain card is like, I think the eight in that deck that he was accused of, an eight and nine, were slightly different symmetry wise. So he can now ask the dealer actually to rotate it to check the symmetry. So you would ask the dealer to rotate the card to see that there's, to detect the asymmetry of the back of the card. And now he knows which cards are eights and nines and, or likelier to be eights and nines. And he was using that information to play poker and win a lot of money, but it's just a slight advantage.

• 2:16:23Lex Fridman?

  And his cases, and in fact, the judge found this, that he's not actually cheating, but it's not right. You can't use this kind of extra information. So it's fascinating, you can discover these little holes in games if you pay close enough attention.

• 2:16:37Andrew D. Huberman?

  Yeah, it's fascinating and I think that, you know, I did watch that clip about the potential of cheating event in chess and the fact that a number of chess players admit to cheating at some point in their career. Very, very interesting.

• 2:16:53Lex Fridman?

  It was online, so online cheating is easier, right? When you're playing, online cheating in a game where the machine is much better than the human, it's very difficult to prove that you're human. And that applies, by the way, another really big thing is in social media, the bots, to, if you're running a social media company, you have to deal with the bots. And they become, one of the really exciting things in machine learning and artificial intelligence to me is the very fast improvement of language models. So neural networks that generate text, then interpret text, that generate from text images and all that kind of stuff. But that's, you're now going to create. Incredible bots that look awfully a lot like humans.

• 2:17:35Andrew D. Huberman?

  Well, at least they're not gonna be those crypto bots that seem to populate my comment section when I post anything on Instagram. I actually delete those even though they add to the comment roster and, you know, if they bother me so much.

• 2:17:47Lex Fridman?

  Yeah.

• 2:17:48Andrew D. Huberman?

  Um, I spend, you know, at least 10, 15 minutes on each post just deleting those. I don't know what they need to do, but I'm not interested in those, whatever it is they're offering. Um, speaking of non-bots, I'm gonna assume that all the questions are not from bots. There are a lot of questions here, more than 10,000 questions, goodness. I'll just take a few, working from top to bottom.

• 2:18:16Andrew D. Huberman?

  What ideas have you been wrestling with lately? And I think about the company as one, but as I scroll to the next, what are some others?

• 2:18:25Lex Fridman?

  Well, some of the things we've talked about, which is,

• 2:18:33Lex Fridman?

  uh, the ideas of how to understand what is true, what is true about a human being, how to reveal that, how to reveal that to a conversation, how to challenge that properly, that it leads to understanding, not division. So that applies to everybody from Donald Trump to Vladimir Putin.

• 2:18:54Lex Fridman?

  Also, another idea is there's a deep distrust of science and trying to understand, the growing distrust of science, trying to understand what's the role of those of us that have a foot in the scientific community, how to be, how to regain some of that trust.

• 2:19:14Lex Fridman?

  Also, there's, uh, as we talked about, the, um, how to find and how to, yeah, how to, how to find and how to maintain a good relationship. I mean, that's really been, I've, I've never felt quite as lonely as I have this year with Ukraine. It's just like, so many times I would just lay there and just feeling so deeply alone because I felt that my home, not my home like literally, because I'm an American, I love, I'm a proud American, I'll die an American, but my home in the sense of my generationally, my family's home, is now going, is now, has been changed forever.

• 2:19:56Lex Fridman?

  There's no more being proud of being from the former Russia or Ukraine. It's just, it's now a political message to say, to show your pride. And so it's been extremely lonely within that world. If with all the things I'm pursuing, how do you find a successful relationship? That's been, that's been tough. But obviously, and there's a huge number of technical ideas with a startup of like, how the hell do you make this thing work?

• 2:20:22Andrew D. Huberman?

  Well, the, the relationship topic is one we talked a little bit about. And last time we, we touched on, I mean, a little bit more detail. Um, we're going to come back to that. Um, so I've made a note here. Um, what or who inspired Lex you to wear a suit every time you podcast? That's a good question. I don't know the answer to that.

• 2:20:44Lex Fridman?

  So there's two, two answers to that question. One is a suit and two is a black suit and black tie. Cause I used to do, I used to have more variety, which is like, there, it was always a black suit, but I would sometimes do a red tie and a blue tie. Um, but that was mostly me trying to fit into society. Cause like varieties, you're supposed to have some variety. What inspired me is the, at first was a general culture that, that doesn't take itself seriously in terms of how you present yourself to the world. So in academia, in the tech world, just at Google, everybody was wearing like pajamas and like very relaxed in the, in the tech.

• 2:21:28Lex Fridman?

  I don't know how it is in the science, in the like chemistry, biology and so on. But in, um, computer science, everybody was like very, I mean, very relaxed in terms of the stuff they wear. So I wanted to try to really take myself seriously and take every single moment seriously, everything I do seriously. And the suit made me feel that way. I don't know how it looks, but it made me feel that way. And I think in terms of people I look up to that wore a suit that made me think of that is, is probably Richard Feynman. I see-

• 2:21:59Andrew D. Huberman?

  He's a wonderful human being.

• 2:22:01Lex Fridman?

  I see him as like the epitome of class and humor and brilliance. And, you know, obviously I can never come close to that kind of, um,

• 2:22:13Lex Fridman?

  You know, be able to simply explain really complicated ideas and to have humor and wit, but definitely aspire to that. And then there's just the, you know, Mad Men, that whole era of the 50s, the classiness of that. There's something about a suit that both removes the importance of fashion from the character. You see the person. I think, uh, not to, I forgot who said this, might be like Kocouchev or somebody like this, is that, you know, you, you, uh, wear a shabby dress and everyone sees the dress. You wear a beautiful dress and everybody sees the woman.

• 2:22:57Lex Fridman?

  So in that sense, I always, uh, hopefully I'm quoting that correctly, but, um.

• 2:23:02Andrew D. Huberman?

  Sounds good.

• 2:23:03Lex Fridman?

  I, I think there's a sense in which a simple classy suit allows people to focus on your character and then do so like with the full responsibility of that, like this is who I am.

• 2:23:18Andrew D. Huberman?

  Yeah, I love that. And I, I love what you said just prior to that. You know, my father, who again is always asking me why I don't dress formally like you do, always said to me growing up, if you overdress slightly, at least people know that you took them seriously. So it's a sign, a sign of respect for your audience too, in my eyes. Someone asked, is there an AI equivalent of psychedelics? And I, I'm assuming they mean, uh, is there something that machines can do for themselves in order to alter their neural circuitry through unconventional activation patterns?

• 2:23:56Lex Fridman?

  Yes, obviously. Well, I don't know exactly how psychedelics work, but you, you can see that with all the diffusion models now with DALL-E and stable diffusion that generates from text art. And there's a. Is basically a small injection of noise into a system that has a deep representation of visual information. So is able to convert text to art, introducing uncertainty into that, noise into that. That's kind of maybe, I could see that as a parallel to psychedelics and is able to create some incredible things.

• 2:24:37Lex Fridman?

  From a conceptual understanding of a thing, it can create incredible art that no human, I think, could have at least easily created through a bit of introduction of randomness. Randomness does a lot of work in the machine learning world, just enough.

• 2:24:56Andrew D. Huberman?

  There are a lot of requests of you for relationship, a lot of requests about statistics about you, data about you specifically. Flipping past those, what was the hardest belt to achieve in jujitsu? I would have assumed the black belt, but is that actually true?

• 2:25:18Lex Fridman?

  No, I mean, everybody has a different journey through jujitsu, as people know. For me, the black belt was the ceremonial belt, which is not usually the case, because I fought the wars, like, I trained twice a day for, I don't know how many years, seven, eight years, I competed nonstop. I competed against people much better than me. I competed against many and beaten many black belts and brown belts. I think, for me personally, the hardest belt was the brown belt. Because for people who know jujitsu, the size of tournament divisions for blue belts

• 2:26:03Lex Fridman?

  and purple belts is just humongous. Like Worlds, when I competed at Worlds, it was like 140 people in a division, which means you have to win, I forget how many times, but seven, eight, nine times in a row to medal. And so... I just had to put in a lot of work during that time. And especially for competitors and structures usually really make you earn a belt. So to earn the purple belt was extremely difficult, extremely difficult. And then to earn the brown belt means I had to compete nonstop against other purple belts, which are young, you're talking about like the people that usually compete are like 23, 24, 25 year olds that are like shredded, incredible cardio.

• 2:26:46Lex Fridman?

  They can, for some reason, are in their life worth they can do, no kids, nothing. They can dedicate everything to this pursuit. So they're training two, three, four times a day. Diet is on point. You're going and for me, because you know, they're usually bigger and taller than me and just more aggressive, actual good athletes. Yeah, I had to go through a lot of wars to earn that brown belt.

• 2:27:09Andrew D. Huberman?

  I gotta try this jujitsu thing.

• 2:27:11Lex Fridman?

  Yeah, you should, but it's a different.

• 2:27:13Andrew D. Huberman?

  Well, I try, I did the one class, but I really want to embrace it.

• 2:27:17Lex Fridman?

  As you know, many pursuits like jujitsu are different. If you do it in your twenties and thirties and later, it's like, it's a different. You can't, you're not, you know, you can have a bit of an ego in your twenties. You can have that fire under you, but you should be sort of more zen like and wise and patient later in life.

• 2:27:37Andrew D. Huberman?

  Well, one would hope. That's the wisdom.

• 2:27:41Lex Fridman?

  Well, I think Rogan is still a meathead. He still goes hard and crazy and he's still super competitive on that. So some people can, Jaco is somebody like that.

• 2:27:51Andrew D. Huberman?

  Well, whatever they're doing, they're doing something right because they're still in it. And that's super impressive. There were far too many questions to ask all of them, but several, if not many, asked a highly appropriate question for where we are in the arc of this discussion. And this is one admittedly that you ask in your podcasts all the time, but I get the great pleasure of being in the question asker seat today. And so what is your advice to young people?

• 2:28:27Lex Fridman?

  So I just gave a lecture at MIT and

• 2:28:33Lex Fridman?

  the amount of love I got there is incredible. And so, of course, what you're, who you're talking to is usually undergrads, maybe young graduate students. And so there, one person did ask for advice as a question at the end. I did a bunch of Q and A. So my answer was that the world will tell you to find a work-life balance, to, to sort of explore, to try to,

• 2:29:06Lex Fridman?

  try different fields to see what you really connect with, you know, variety, general education, all that kind of stuff. And I said, in your twenties, I think you should find one thing you're passionate about and work harder at that than you worked at anything else in your life. And if it destroys you, it destroys you. That's advice for in your twenties. I don't know how universally true that advice is, but I think at least give that a chance, like sacrifice, real sacrifice, towards a thing you really care about and work your ass off. That said, I've met so many people and I'm starting to think that advice is, is best applied

• 2:29:49Lex Fridman?

  or best tried in the engineering disciplines, especially programming. I think there's a bunch of disciplines in which you can achieve success with much fewer hours. And it's much more important to actually have a clarity of thinking and great ideas and have an energetic mind. Like the grind in certain disciplines does not produce great work. I just know that in computer science and programming, it often does. Some of the best people ever that have built systems, have programmed systems, I usually like the John Carmack kind of people that drink soda, eat pizza and program, you know, 18 hours a day. So I don't know, actually, you have to, I think, really go discipline specific.

• 2:30:34Lex Fridman?

  So my advice applies to my own life, which has been mostly spent behind a computer. And for that, you really, really have to put in the hours. And what that means is essentially it feels like a grind. I do recommend that you should at least try it in your own. That if you interview some of the most accomplished people ever, I think if they're honest with you, they're gonna talk about their twenties as a journey of a lot of pain and a lot of really hard work. I think what really happens, unfortunately, is a lot of those successful people later in life will talk about work-life balance. They'll say, you know what I learned from that process is that it's really important,

• 2:31:18Lex Fridman?

  you know, to get like sun in the morning, to have health, to have good relationships.

• 2:31:24Andrew D. Huberman?

  Hire a chef.

• 2:31:24Lex Fridman?

  Exactly. But like, I think you have forgot, those people have forgotten the value of the journey they took to that lesson. I think work-life balance is best learned the hard way. My own perspective, there's certain things you can only learn the hard way. And so you should learn that the hard way. Yeah, so that's definitely advice. And I should say that I admire people that work hard. If you wanna get on my good side, I think are the people that give everything they got towards something. It doesn't actually matter what it is, but towards achieving excellence in a thing.

• 2:32:07Lex Fridman?

  That's the highest thing that we can reach for as human beings, I think, is excellence at a thing.

• 2:32:16Andrew D. Huberman?

  I love it. Well, speaking of excellence at a thing, whether or not it's teaching at MIT, or the podcast, or the company that resides in the near future that you create. I, once again, am speaking for an enormous number of people that excellence and hard work certainly are woven through everything that you do. Every time I sit down with you, I begin and finish with such an immense feeling of joy and appreciation and gratitude. And it wouldn't be a Lex Fridman podcast, or in the case of Lex Fridman being a guest on a podcast, if the word love weren't mentioned at least 10 times.

• 2:33:01Andrew D. Huberman?

  So the feelings of...

• 2:33:04Andrew D. Huberman?

  Gratitude for all the work you do for taking the time here today to to share with us what you're doing, your thoughts, your insights, your what you're perplexed about and what drives you and your callings.

• 2:33:16Lex Fridman?

  Can I read a poem?

• 2:33:16Andrew D. Huberman?

  Yes, please.

• 2:33:19Andrew D. Huberman?

  He was trying to cut me off, but I was getting a little long.

• 2:33:22Lex Fridman?

  No, no, no, this is, I was thinking about this recently. It's one of my favorite Robert Frost poems. And I

• 2:33:30Lex Fridman?

  because I wrote several essays on it, as you do, because I think it's a popular one that's read. And so essays being like trying to interpret poetry and it's one that sticks with me. I mean, both it's calm beauty, but in the seriousness of what it means, because I ultimately think it's the, so stopping by woods on a snowy evening. I think it's ultimately a human being, a man asking the, the old Sisyphus, the old Camus question of why live? I think this poem, even though it doesn't seem like it, is a question of a man contending with suicide and choosing to live.

• 2:34:12Lex Fridman?

  Whose woods these are, I think I know. His house is in the village, though. He will not see me stopping here to watch his woods fill up with snow. My little horse must think it queer to stop without a farmhouse near, between the woods and frozen lake, the darkest evening of the year. He gives his harness bells a shake to ask if there's some mistake. The only other sound's the sweep of easy wind and downy flake. The woods are lovely, dark and deep, but I have promises to keep and miles to go before I sleep. And miles to go before I sleep. The woods representing the darkness, the comfort of the woods representing death.

• 2:34:57Lex Fridman?

  And he is a man choosing to live. Yeah, I think about that often, especially in my darker moments. Is you have promises to keep.

• 2:35:12Lex Fridman?

  Thank you for having me, Andrew. You're a beautiful human being. I love you, brother.

• 2:35:17Andrew D. Huberman?

  I love you, brother.
