Richard Sutton – Father of RL thinks LLMs are a dead end

Richard Sutton is the father of reinforcement learning, winner of the 2024 Turing Award, and author of The Bitter Lesson. http://www.incompleteideas.net/IncIdeas/BitterLesson.html And he thinks LLMs are a dead end. After interviewing him, my steel man of Richard’s position is this: LLMs aren’t capable of learning on-the-job, so no matter how much we scale, we’ll need some new architecture to enable continual learning. And once we have it, we won’t need a special training phase — the agent will just learn on-the-fly, like all humans, and indeed, like all animals. This new paradigm will render our current approach with LLMs obsolete. In our interview, I did my best to represent the view that LLMs might function as the foundation on which experiential learning can happen… Some sparks flew.

  Today, I'm chatting with Richard Sutton, who is one of the founding fathers of reinforcement learning and inventor of many of the main techniques used there, like TD learning and policy gradient methods. And for that, he received this year's Turing Award, which, if you don't know, is basically the Nobel Prize for Computer Science. Richard, congratulations.

• 0:17Speaker 01

  Thank you, Drakas.

• 0:18Dwarkesh Patel?

  And thanks for coming on the podcast.

• 0:20Speaker 01

  It's my pleasure.

• 0:21Dwarkesh Patel?

  OK, so first question. My audience and I are familiar with the LLM way of thinking about AI. Conceptually, what are we missing in terms of thinking about AI from the RL perspective?

• 0:34Speaker 01

  Well, yes, I think it's really quite a different point of view, and it's it can easily get separated and lose the ability to talk to each other. And yeah, large language models have become such a big thing. Generative AI in general, a big thing. And our field is subject to bandwagons and fashions. So we lose track of the basic, basic things. Because I consider reinforcement to be basic AI. And what is intelligence? The problem is to understand your world. And reinforcement learning is about understanding your world, whereas large language models are about mimicking people, doing what people say you should do. They're not about figuring out what to do.

• 1:19Dwarkesh Patel?

  Huh. I guess you would think that to emulate the trillions of tokens in the corpus of internet text, you would have to build a world model. In fact, these models do seem to have very robust world models, and they're the best world models we've made to date in AI. Right? So what do you think that's missing?

• 1:38Speaker 01

  I would disagree with most of the things you just said.

• 1:40Dwarkesh Patel?

  Great.

• 1:42Speaker 01

  Just to mimic what people say is not really to build a model of the world at all. I don't think, you know, you're mimicking things that have a model of the world, the people. But I don't want to approach the question in an adversarial way. But I would question the idea that they have a world model. So a world model would enable you to predict what would happen.

• 2:05Dwarkesh Patel?

  Right.

• 2:05Speaker 01

  They have the ability to predict what a person would say. They don't have the ability to predict what will happen. What we want, I think, to quote Alan Turing, what we want is a machine that can learn from experience.

• 2:18Dwarkesh Patel?

  Right.

• 2:19Speaker 01

  Where experience is the things that actually happen in your life. You do things, you see what happens, and that's what you learn from.

• 2:28Dwarkesh Patel?

  Yeah.

• 2:29Speaker 01

  The large language models learn from something else. They learn from here's a situation and here's what a person did. And implicitly, the suggestion is you should do what the person did.

• 2:38Dwarkesh Patel?

  Right. I guess maybe the crux, and I'm curious if you disagree with this, is some people will say, okay, so this imitation learning has given us a good prior, or given these models a good prior. But reasonable ways to approach problems. And as we move towards the era of experience, as you call it, this prior is going to be the basis on which we teach these models from experience, because this gives them the opportunity to get answers right some of the time. And then on this, you can build, you can train them on experience. Do you agree with that perspective?

• 3:12Speaker 01

  No, I agree that it's the large language model perspective.

• 3:16Dwarkesh Patel?

  Right.

• 3:16Speaker 01

  I don't think it's a good perspective.

• 3:18Dwarkesh Patel?

  Yeah.

• 3:19Speaker 01

  Yeah.

• 3:19Dwarkesh Patel?

  Here's why.

• 3:20Speaker 01

  So to be a prior for something, there has to be a real thing. I mean, a prior bit of knowledge should be the basis for actual knowledge. What is actual knowledge? There's no definition of actual knowledge in that large language framework. What makes an action a good action to take? You recognize the value, the need for continual learning.

• 3:44Dwarkesh Patel?

  Right.

• 3:45Speaker 01

  So if you need to learn continually, continually means learning during the normal interaction with the world.

• 3:50Dwarkesh Patel?

  Yeah.

• 3:51Speaker 01

  And so then there must be some way during the normal interaction to tell what's right.

• 3:56Dwarkesh Patel?

  Yep.

• 3:57Speaker 01

  Okay, so. Is there any way for it to tell in the large language model setup to tell what's the right thing to say? You will say something and you will not get feedback about what the right thing to say is because there's no definition of what the right thing to say is. There's no goal.

• 4:15Dwarkesh Patel?

  Right.

• 4:16Speaker 01

  If there's no goal, then there's one thing to say, another thing to say, there's no right thing to say.

• 4:21Dwarkesh Patel?

  Right.

• 4:22Speaker 01

  So there's no ground truth. You can't have prior knowledge if you don't have ground truth because the prior knowledge is supposed to be a hint or an initial belief about what the truth is.

• 4:32Dwarkesh Patel?

  Yeah.

• 4:33Speaker 01

  But there isn't any truth. There's no right thing to say. Right? Now, in reinforcement learning, there is a right thing to say or right thing to do because the right thing to do is the thing that gets you reward.

• 4:43Dwarkesh Patel?

  Right.

• 4:44Speaker 01

  So we have a definition of what the right thing to do is and so we can have prior knowledge or knowledge provided by people about what the right thing to do is and then we can check it to see because we have a definition of what the actual right thing to do is.

• 4:58Dwarkesh Patel?

  Yeah.

• 4:59Speaker 01

  Now, an even simpler case is when you have, you're trying to make a model of the world, when you predict what will happen, you predict and then you see what happens.

• 5:07Dwarkesh Patel?

  Mm-hmm.

• 5:07Speaker 01

  Okay, so there's ground truth. There's no ground truth in, in large language models because you don't have a prediction about what will happen next. If you say something in your, in your conversation, there's, the large language models have no prediction about what the person will say in response to that or what, what the response will be.

• 5:29Dwarkesh Patel?

  I mean, I think they do. Like they, you can literally ask them, what, what would you anticipate a user might say in response? And they have a prediction.

• 5:35Speaker 01

  Oh, no, they, they were, they will respond to that question, right?

• 5:38Dwarkesh Patel?

  Yeah.

• 5:39Speaker 01

  But they have no prediction in the substantive sense that they won't be surprised by what happens. And if something happens that isn't what you might say they predicted, they will not change because an unexpected thing has happened and they're...

• 5:53Speaker 01

  To learn that, they'd have to make an adjustment.

• 5:56Dwarkesh Patel?

  So I think a capability like this does exist in context. So it's interesting to watch a model do chain of thought. And then suppose it's trying to solve a math problem. It'll say, OK, I'm going to approach this problem using this approach at first. And it'll write this out and be like, oh, wait, I just realized this is the wrong conceptual way to approach the problem. I'm going to restart by this another approach. And that flexibility does exist in context, right? Do you have something else in mind? Or do you just think that you need to extend this capability across longer horizons?

• 6:28Speaker 01

  I'm just saying, they don't have a, in any meaningful sense, they don't have a prediction of what will happen next. And they will not be surprised by what happens next. They'll not make any changes if something happens.

• 6:41Dwarkesh Patel?

  But isn't that?

• 6:42Speaker 01

  Based on what happens.

• 6:43Dwarkesh Patel?

  Isn't that literally what next token prediction is? Prediction of what's next and then updating on a surprise?

• 6:47Speaker 01

  Next token is what they should say, what the action should be. It's not what the world will give them in response to what they do. Let's go back to their lack of goal. For me, having a goal is the essence of intelligence.

• 7:02Dwarkesh Patel?

  Right.

• 7:03Speaker 01

  Something is intelligent if it can achieve goals. I like John McCarthy's definition that intelligence is the computational part of the ability to achieve goals.

• 7:11Dwarkesh Patel?

  Yeah.

• 7:11Speaker 01

  So you have to have goals. You're not, you're just, you're just, you're just a behaving system. You're not, you're not anything special. You're not intelligent.

• 7:21Dwarkesh Patel?

  Right.

• 7:22Speaker 01

  And you agree that large language models don't have goals.

• 7:25Dwarkesh Patel?

  I think, no, they have a goal.

• 7:26Speaker 01

  What's the goal?

• 7:27Dwarkesh Patel?

  Next token prediction.

• 7:29Speaker 01

  That's not a goal. It doesn't, it doesn't change the world. You know, tokens come at you. And if you predict them, you don't influence them.

• 7:39Dwarkesh Patel?

  Oh, yeah. It's not a goal about the external world.

• 7:43Speaker 01

  Yeah, it's not a goal. It's not a substantive goal. It's not, you can't look at a system and say, oh, it has a goal if it's just sitting there predicting and being happy with itself that it's predicting accurately.

• 7:55Dwarkesh Patel?

  I guess maybe the bigger question I want your, I want to understand is why you don't think doing RL on top of LLMs is a productive direction because we seem to be able to give these models a goal of solving difficult math problems. And they're in many ways at the very peaks of human level in the capacity to solve math lumpia type problems, right? They got gold at IMO. So it seems like the model which got gold at the International Math Olympia does have the goal of getting math problems, right? So why can't we extend this to different domains?

• 8:27Speaker 01

  Well, the math problems are different. Making a model of the physical world and carrying out the consequences of mathematical assumptions or operations.

• 8:39Dwarkesh Patel?

  Right.

• 8:39Speaker 01

  Those are very different things. Like the empirical world has to be learned. You have to learn the consequences. Whereas the math is more just computational. It's more like standard planning. So there you can, you can, they can have a goal to, to, to find the proof. And they are in some way given that goal to find the proof.

• 9:09Dwarkesh Patel?

  Right. So, I mean, it's interesting because you wrote this essay in 2019 titled The Bitter Lesson, and this is the most influential essay perhaps in the history of AI. But people have used that as a justification for scaling up LLMs because in their view, this is the one scalable way we have found to pour ungodly amounts of compute into learning about the world. And so it's interesting that your perspective is that the LLMs are actually not bitter lesson pilled.

• 9:41Speaker 01

  It's an interesting question whether large language models are, are a case of the bitter lesson.

• 9:49Dwarkesh Patel?

  Yeah.

• 9:50Speaker 01

  Because they are clearly a way of using massive computation, things that will scale with computation up to, up to the limits of the internet.

• 10:01Dwarkesh Patel?

  Yeah.

• 10:03Speaker 01

  But they're also a way of putting in lots of.

• 10:08Speaker 01

  Human knowledge. And so, so this is an interesting question. It's a sociological or industry question. Will they reach the limits of, of, of the data? And, and be superseded by things that, that are, that are, can get more data just from experience rather than from, from people. In some ways, it's a classic case of the, of the, of the bitter lesson. With the more, the more human knowledge we put into the large language models, the better they can do. And so it feels good.

• 10:49Speaker 01

  And yet, one, well, I in particular, expect there to be systems that can learn from experience, which could well perform much, much better and be much more scalable. In which case, it will be another instance of the bitter lesson, that the things that, that used human knowledge were eventually superseded by things that just trained from experience and computation.

• 11:17Dwarkesh Patel?

  I guess that doesn't seem like the crux to me, because I think those people would also agree that the overwhelming amount of compute in the future will come from learning from experience. They just think that the scaffold or the basis of that, the thing you'll start with in order to pour in the compute to do this future experiential learning or on the job learning will be L L M's. And so I guess I, I still don't understand why this is the wrong starting point altogether, why we need a whole new architecture to begin doing experiential continual learning, and why we can't start with L L M's to do that.

• 11:58Speaker 01

  Well, in every case of the bitter lesson, you know, you could start with human knowledge.

• 12:03Dwarkesh Patel?

  Right.

• 12:04Speaker 01

  And then just, and then do the scalable things.

• 12:06Dwarkesh Patel?

  Yeah.

• 12:07Speaker 01

  That's always the case. And there's no, never any reason why that has to be bad.

• 12:11Dwarkesh Patel?

  Right.

• 12:12Speaker 01

  But in fact, and in practice, it has always turned out to be bad. Because people get locked into the human knowledge approach and they psychologically, or, you know, now I'm, now I'm speculating why it is. But this is what has always happened.

• 12:27Dwarkesh Patel?

  Yeah.

• 12:28Speaker 01

  That, uh, yeah, they get, they get, their lunch gets eaten by the methods that are truly scalable.

• 12:34Dwarkesh Patel?

  Yeah. Give me a sense of what the scalable method is.

• 12:37Speaker 01

  The scalable method is you learn from experience. Um, you, uh, you, you try things, you see what, you see what works. No one, no one has to tell you. First of all, you have a goal. So without a goal, uh, there's no sense of right or wrong or better or worse. So large language models are trying to get by without having a goal or a sense of better or worse. That's just, you know, it's exactly starting in the wrong place.

• 13:03Dwarkesh Patel?

  Maybe it's, um, interesting to compare this to humans. So in both the case of learning from imitation versus experience and on the question of goals, I think there's some interesting analogies. So, you know, kids will initially learn from imitation. Uh, you don't think so?

• 13:24Speaker 01

  No, of course not.

• 13:26Dwarkesh Patel?

  Really?

• 13:27Speaker 01

  Yeah.

• 13:28Dwarkesh Patel?

  I think kids just like watch people, they like kind of try, try to like say the same words.

• 13:32Speaker 01

  These kids?

• 13:34Dwarkesh Patel?

  I, I think the level of-

• 13:35Speaker 01

  What about the first six months?

• 13:37Dwarkesh Patel?

  I think they're kind of, kind of imitating things. They're trying to like make their mouth sound the way they see their mother's mouth sound. And then they'll say the same words without understanding what they mean. And as you get older, the complexity of the imitation they do increases. So that's, you're, you're, you're, you're imitating maybe the skills that your, uh, people in your band are, uh, using to hunt down the deer or something. And then you go into the learning from experience, RRL regime, but I think there's a lot of imitation learning happening. With humans.

• 14:04Speaker 01

  It's surprising. Yeah, you can have such a different point of view.

• 14:07Dwarkesh Patel?

  Yeah.

• 14:07Speaker 01

  When I see kids, I see kids just trying things and like waving their hands around and moving their eyes around. And no one, no, no one tells them, there's no, there's no imitation for how they move their eyes around, or even the sounds they make. They may, they may want to create the same sounds, but the, the actions, you know, the thing that the infant actually does, there, there's no targets for that. There are no examples for that.

• 14:37Dwarkesh Patel?

  I agree that doesn't explain everything infants do, but I think it guides the learning process. I mean, even L L M, when it's trying to predict the next token early in training, it will like make a guess. It'll be different from what like it actually sees. And in some sense, it's like very short horizon R L, where it's like making this guess of like, I think this token will be this. It's actually the other thing, similar to how a kid will try to say a word. It comes out wrong.

• 14:58Speaker 01

  The, the large language models is learning from training data. It's not learning from experience. It's, it's learning from something that will never be available during its normal life.

• 15:09Speaker 01

  There's never any training data that says you should do this action in normal life.

• 15:15Dwarkesh Patel?

  I, I think this is maybe more of a semantic distinction, like what do you call school? Is that not training data? You're not like going to school because it's like.

• 15:23Speaker 01

  School is much later. Okay, I shouldn't have said never, but, but I, I don't know. I think I would even say about school, but formal schooling is, is the exception. You shouldn't base your theories on that.

• 15:35Dwarkesh Patel?

  Learning where I think it's just a sort of programming in your biology that like, early on, you're not that useful. And then like kind of why you exist is to understand the world and like learn how to interact with it.

• 15:48Dwarkesh Patel?

  And it seems kind of like a training phase. I agree that then there's like a sort of more gradual. There's not a sharp cutoff to like training to deployment, but there seems to be this like initial training phase, right?

• 15:59Speaker 01

  There's nothing where you have training of what you should do. There's nothing. You, you, you see things that happen. You're not, you're not told what to do. Don't be difficult. I mean, this is obvious.

• 16:14Dwarkesh Patel?

  I mean, you're like literally taught what to do. This is like where the word training comes from is from humans, right?

• 16:19Speaker 01

  So I don't think learning is really about training. I think learning is about about learning. It's about an active process. The child tries things and sees what happens.

• 16:31Dwarkesh Patel?

  Right.

• 16:31Speaker 01

  Yeah, it does not. We don't think we don't think about training and we think of an infant growing up. These things are actually rather well understood. If you go to look about how psychologists think about learning, there's nothing like imitation. Maybe there are some extreme cases where humans might do that or appear to do that, but there is no basic animal learning process called imitation. The basic animal learning process is for prediction and for trial and error control. I mean, it's really interesting how sometimes the most hardest things to see are the obvious ones.

• 17:10Speaker 01

  It's obvious if you just look at animals and how they learn and you look at psychology and how our theories of them. It's obvious that supervised learning is not part of the way animals learn. We don't have we don't have examples of desired behavior. What we have is examples of things that happen, things, one thing that followed another. And we have examples of we did something and and and and there were consequences. But there are no examples of supervised learning. I mean, there are no supervised learning is not something that happens in nature. And, you know, school, even if that was a case, you know, we should forget about it because it's

• 17:54Speaker 01

  it's just that's some special thing that happens in people. It doesn't happen broadly in nature. And, you know, squirrels don't go to school. Squirrels can learn all about the world. It's absolutely obvious, I would say, that supervised learning doesn't happen in animals.

• 18:11Dwarkesh Patel?

  So I interviewed this psychologist and anthropologist Joseph Henrich, who has done work about cultural evolution and basically how did what, you know, what distinguishes humans? And how do humans pick up knowledge?

• 18:26Speaker 01

  Why are you trying to distinguish humans?

• 18:30Speaker 01

  Humans are animals. What we have in common is more interesting. What we have, what distinguishes us, we should be paying less attention to.

• 18:38Dwarkesh Patel?

  I mean, we're trying to replicate intelligence, right? So if you want to understand what is it that enables humans to go to the moon or to build semiconductors, I think the thing we want to understand is the thing that makes no animal can go to the moon or make semiconductors. So we want to understand what makes humans special.

• 18:54Speaker 01

  So I like the way you consider that obvious. Because I consider the opposite obvious. Yeah, I think we need to, we have to, we have to understand how we are animals. And if we understood a squirrel, I think we'd have a, we'd be almost all the way there. It's understanding human intelligence. The, the language part is just a small veneer on the surface. Okay, so this is great. You know, we're finding out the very different ways that we're thinking. We're not arguing. We're trying to share, share our different ways of thinking with each other.

• 19:29Dwarkesh Patel?

  Yeah, and I think argument is useful, so.

• 19:33Speaker 01

  Yeah.

• 19:33Dwarkesh Patel?

  But I do want to complete this thought. So Joseph Henrich has this interesting theory that if you, a lot of the skills that humans have had to master in order to be successful, and we're not talking about, you know, last thousand years or last 10,000 years, but hundreds of thousands of years. You know, the world is really complicated and it's not possible to reason through how to, let's say, hunt a seal if you're living in the Arctic. And so there's this many, many step long process of how to make the bait and how to find the seal and then how to process the food in a way that makes sure you won't get poisoned. And it's not possible to reason through all of that.

• 20:16Dwarkesh Patel?

  And so over time, yes, there's this like larger process of.

• 20:22Dwarkesh Patel?

  Whatever analogy you want to use, maybe R L something else where culture as a whole has figured out how to

• 20:29Dwarkesh Patel?

  find and kill and eat seals. But then what is happening when through generations this knowledge is transmitted is in his view that like you just have to imitate your elders in order to learn that skill because you can't you can't think your way through how to hunt and kill and process a seal. You have to just watch other people maybe make tweaks and adjustments. And that's how culture, knowledge accumulates. But the the initial step of the cultural gain has to be imitation. But maybe you think about it a different way?

• 21:00Speaker 01

  No, I think about it the same way.

• 21:02Dwarkesh Patel?

  Okay.

• 21:02Speaker 01

  But still, it's a small thing on top of basic trial and error learning, prediction learning. And that's what distinguishes us perhaps from from many animals.

• 21:17Speaker 01

  But we're an animal first.

• 21:20Dwarkesh Patel?

  Yeah.

• 21:20Speaker 01

  And and we were an animal before we had language and all these other things.

• 21:26Dwarkesh Patel?

  I do think you make a very interesting point that continual learning is a capability that most mammals have, I guess all mammals have. So it's quite interesting that we have something that all mammals have, but our AI systems don't have. Right? Whereas maybe like the ability to understand math and solve difficult math problems depends on how you define math, but like this is a capability our AIs have, but that no, almost no animal has. And so it's quite interesting what ends up being difficult and what ends up being easy.

• 21:58Speaker 01

  Moravec's Paradox.

• 21:59Dwarkesh Patel?

  That's right. For the era of experience to commence, we're going to need to train AIs in complex real world environments. But building effective R L environments is hard. You can't just hire a software engineer and have them write a bunch of cookie cutter validation tests. Real world domains are messy. You need deep subject matter experts to get the data, the workflows and all the subtle rules right. When one of Labelbox's customers wanted to train an agent to shop online, Labelbox assembled the team with a ton of experience engineering internet storefronts. For example, the team built a product catalog that could be Updated during the episode because most shopping sites have constantly changing state. They also added a Redis cache to simulate stale data since that's how real ecommerce sites actually work.

• 22:42Dwarkesh Patel?

  These are the kinds of things that you might not have naively thought to do, but that Labelbox can anticipate. These details really matter. Small tweaks are often the difference between cool demos and agents that can actually operate in the real world. So whether it's correcting traces that you already produced or building an entirely new suite of environments, Labelbox can help you turn your RL projects into working systems. Reach out at labelbox.com/dwarcash. All right, back to Richard. This alternative paradigm that you're imagining.

• 23:12Speaker 01

  The experiential paradigm.

• 23:14Dwarkesh Patel?

  Yes.

• 23:14Speaker 01

  Let's lay out a little bit about what it is. It says that experience, action, sensation, well, sensation, action, reward. And then this happens on and on and on, makes for life. It's, it says that this is the foundation and the focus of intelligence. Intelligence is about taking that stream and altering the actions to increase the rewards in the stream.

• 23:41Dwarkesh Patel?

  Right.

• 23:41Speaker 01

  So learning then is from the stream and learning is about the stream. So it's that, that second part is, is, is particularly telling. You know, that what you learn, your knowledge, your knowledge is about the stream. Your knowledge is about if you do some action, what will happen? Or it's about which events will follow other events. It's about the stream. It's the content of the knowledge is, is statements about the stream. And so because it's, it's a statement about the stream, you can test it by comparing it to the stream and you can learn continually.

• 24:18Dwarkesh Patel?

  Hmm. So when you're imagining this future continual learning agent.

• 24:22Speaker 01

  They're not future. Of course, we, they exist all, all the time. It's, I mean, this is what reinforcement learning paradigm is, learning from experience.

• 24:29Dwarkesh Patel?

  Yeah. I guess the, maybe I would have meant to say is, uh, human level, general continual learning agent.

• 24:34Speaker 01

  Uh huh.

• 24:36Dwarkesh Patel?

  What is their reward function? Is it just predicting the world? Is it, uh, is it then having a specific effect on it? How, what would the general reward function be?

• 24:46Speaker 01

  The reward, uh, function is arbitrary. And, um, so if you're playing chess, it's to win the game of chess. If you were to, uh, if you're a squirrel, maybe the reward has to do with getting nuts.

• 25:01Dwarkesh Patel?

  Right.

• 25:04Speaker 01

  In general, for an animal, you would say the reward is to avoid pain and to acquire pleasure.

• 25:11Dwarkesh Patel?

  Right.

• 25:13Speaker 01

  And there's also would be a component having to do with, I think there would be, should be a component having to do with your increasing understanding of your, of your environment. That would be sort of an intrinsic motivation.

• 25:27Dwarkesh Patel?

  I see. I guess this AI would be deployed to, like, lots of people would want it to be doing lots of different kinds of things.

• 25:36Speaker 01

  Right.

• 25:36Dwarkesh Patel?

  So it's performing the task people want, but at the same time, it's learning about the world from doing that task. And do you, do you imagine, okay, so we get rid of this paradigm where there's training periods and then there's deployment periods. But then is there, do we also get rid of this paradigm when there's the model? And then instances of the model or copies of the model that are, you know, doing certain things? How, how, how do you think about the fact that there, we'd want this thing to be doing different things? We'd want to aggregate the knowledge that it's gaining from doing those different things.

• 26:11Speaker 01

  I don't like the word model when used the way you just did. I, I think a better word would be of the network. So I think you mean the, the network. Maybe there's many networks. So anyway, things would be learned and then you'd have copies and many instances. And sure, you'd want to share knowledge across the instances. And there would be lots of possibilities for doing that, like there is not today. You can't have one child learn, grow up and, and learn about the world and then, and then every new child has to repeat that process. Whereas with AIs, with the digital intelligence, you could hope to do it once and then copy it into the next one as a starting place.

• 26:53Speaker 01

  So this would be a huge savings and I think actually it'd be much more important than, uh, Trying to learn from people.

• 27:01Dwarkesh Patel?

  Hmm hmm. I agree that the kind of thing you're talking about is necessary regardless of whether you start from L L M's or not, right? If you want hu- human or animal level intelligence, you're going to need this capability. Suppose a human is trying to make a startup, right? And this is a thing which has a reward on the order of 10 years. Once in 10 years, you might have an exit where you get, you know, paid out a billion dollars. But humans have this ability to make intermediate auxiliary rewards or have some way of, even when they have extremely sparse rewards, they can still make intermediate steps, having an understanding of like what the next thing you're doing leads to this grander goal we have. And so how do you imagine such a process might play out with AIs?

• 27:43Speaker 01

  So this is something we know very well. And it's the basis of it is temporal difference learning. Where the same thing happens in a less grandiose scale, like when you learn to play chess. You have the grand, the long-term goal is winning the game. And yet you can't, you, you want to be able to learn from shorter term things like, you know, taking your opponent's pieces. And so you do that by having a value function which predicts the long-term outcome.

• 28:11Dwarkesh Patel?

  Right.

• 28:12Speaker 01

  And then if you take the guy's pieces, well, your prediction about the long-term outcome is changed. It goes up, you think you're going to win. And then that increase in your, in your belief immediately quote reinforces the, the move that led to taking the piece. Okay, so we have this long-term 10-year goal of making a startup and making a lot of money. And so when we make progress, we say, oh, I'm, I'm, I'm more likely to achieve the long-term goal and that rewards the, the steps along the way.

• 28:45Dwarkesh Patel?

  Right. And then you also want some ability for information that you're learning. I mean, one of the things that makes humans quite different from these L L M's is that if you're onboarding on a job, you're, you're picking up so much context and information. And that's what makes you useful at the job, right? You're, uh, everything from how your client's preferences to how the company works, to everything. And is the bandwidth of information that you get from a procedure like TD learning high enough to have this like huge pipe of like context and tacit knowledge that you'd need to be picking up in the way humans do when they're, when they're just like deployed?

• 29:24Speaker 01

  I think the crux of this, I'm not sure, but the big world hypothesis seems very relevant. And the reason why humans becoming useful on their job is because they are encountering the particular part of the world.

• 29:40Dwarkesh Patel?

  That's right.

• 29:41Speaker 01

  And it can't have been anticipated and can't all have been put in in advance. The world is so huge that you can't, the dream, as I see it, the dream of large language models is you can teach the agent everything and it will know everything and it won't have to learn anything online.

• 30:01Dwarkesh Patel?

  Right.

• 30:02Speaker 01

  During its life, okay? And your examples are all, well, really you have to because you can, there's lots of, you can teach it, but there's all little idiosyncrasies of the particular life they're leading and the particular people they're working with and what they like as opposed to what average people like.

• 30:19Dwarkesh Patel?

  Right.

• 30:20Speaker 01

  And so that's just saying the world is really big and so you're going to have to learn it along the way.

• 30:25Dwarkesh Patel?

  Yeah, so it seems to me you need two things. One is some way of converting this long run goal reward into smaller auxiliary or, you know, these like predictive rewards of the future reward or the future reward, at least of the final reward. Then you need some other way, initially it seems to me, you need some way of then, okay, I'm, I need to hold on to all this context that I'm gaining as I'm working in the world, right? I'm like learning about my clients, my company, all this information and I'm.

• 31:02Speaker 01

  So I would say you're just doing regular learning.

• 31:04Dwarkesh Patel?

  Yeah.

• 31:05Speaker 01

  Maybe using context because in large language models, all that information has to go into the context window.

• 31:10Dwarkesh Patel?

  Right.

• 31:11Speaker 01

  But in a continual learning setup, it just goes into the weights.

• 31:15Dwarkesh Patel?

  Maybe, yeah, so maybe context is the wrong word to use because I mean a more general thing.

• 31:19Speaker 01

  You learn a policy that's specific to the environment.

• 31:21Dwarkesh Patel?

  Right.

• 31:22Speaker 01

  That you're finding yourself in.

• 31:23Dwarkesh Patel?

  Yeah. The question I'm trying to ask is, you need some way of getting like, how many bits per second are you picking? Like, is a human picking up when they're, you know, out in the world, right? If you're just like interacting over Slack with your work clients and everything.

• 31:39Speaker 01

  So maybe we're trying to ask the question of, it seems like the reward is too small of a thing to do all the learning that we need to do. But of course, we have the sensations. We have all the other information we can learn from.

• 31:53Dwarkesh Patel?

  Right.

• 31:53Speaker 01

  We don't just learn from the reward, we learn from all the data.

• 31:57Dwarkesh Patel?

  Yeah, so what is the learning process which helps you capture that information?

• 32:03Speaker 01

  So now I want to talk about the base common model of the agent with the four parts.

• 32:10Dwarkesh Patel?

  Good.

• 32:10Speaker 01

  So we need a policy. The policy says, in the situation I'm in, what should I do? We need a value function. The value function is the thing that is learned with TD learning. And the value function produces a number. The number says, how well is it going? And then you watch if that's going up and down and use that to adjust your policy. Okay, so those two things. And then there's also the perception component, which is the construction of your state representation. This your sense of where you are now. And the fourth one is what we're really getting at, most transparently, anyway. The fourth one is the transition model of the world. That's why I am uncomfortable just calling everything models, because I want to talk about the model of the world.

• 32:56Speaker 01

  The transition model of the world. Your belief that if you do this, what will happen? What will be the consequences of what you do? So your physics of the world. But it's not just physics, it's also abstract models, like, you know, your model of how you traveled from California up to Edmonton for this podcast. That was a model, and that's a transition model, and that would be learned. And it's not learned from reward, it's learned from you did things, you saw what happened. And you made that model of the world. That is, it will be learned very richly from all the sensation that you receive, not just from the reward. It has to include the reward as well, but that's a small part of the whole model. Small crucial part of the whole model.

• 33:37Dwarkesh Patel?

  Yeah, one of my friends, Toby Ord, pointed out that if you look at the Muze Euro models that Google DeepMind deployed to learn Atari games, that these models were initially not a general intelligence self, but a general framework for training specialized intelligences to play specific games. That is to say that you couldn't, using that framework, train a policy to play both chess and Go and some other game. You had to train each one in a specialized way. And he was wondering whether that implies that reinforcement learning generally, because of this information constraint, you can only learn one thing at a time? The density of information isn't that high? Or whether it was just specific to the way

• 34:22Dwarkesh Patel?

  that Muze Euro was done? And if it's specific to AlphaZero, what needed to be changed about that approach so that it could be a general learning agent?

• 34:33Speaker 01

  The idea is totally general. You know, I do use all the time, as my canonical example, the idea of an AI agent is like a person.

• 34:42Dwarkesh Patel?

  Yeah.

• 34:43Speaker 01

  And people, in some sense, they have just one world they live in, and that world may involve chess, and it may involve Atari games. But those are not a different task or a different world. Those are different states

• 34:58Dwarkesh Patel?

  Right.

• 34:58Speaker 01

  that they encounter. And so the general idea is not limited at all.

• 35:03Dwarkesh Patel?

  So maybe it would be useful to explain what was missing in that architecture or that approach, which this continual learning agent would have?

• 35:17Speaker 01

  They just set it up. They didn't. It was not their ambition to have one agent across those games. If we want to talk about transfer, we should talk about transfer, not across games or across tasks, but transfer between states.

• 35:34Dwarkesh Patel?

  Yeah, I guess I'm curious about Historically, have we seen the level of transfer using RL techniques that would be needed to build this kind of?

• 35:47Speaker 01

  Okay, good, good. We're not seeing transfer anywhere. We're not seeing general. Critical to good performance is that you can generalize well from one state to another state. We don't have any methods that are good at that. What we have are people try different things and they settle on something that, a representation that transfers well or that generalizes well. But we have no, we don't have any automated techniques to promote. We have very few automated techniques to promote transfer and they're not, none of them are used in, in modern deep learning.

• 36:22Dwarkesh Patel?

  Let me paraphrase to make sure that I understood that correctly. It sounds like you're saying that when we do have generalization in these models, that is a result of some sculpted.

• 36:39Speaker 01

  Humans did it.

• 36:40Dwarkesh Patel?

  Yeah.

• 36:41Speaker 01

  The researchers did it. Because there's no other explanation. I mean, gradient descent will not make you generalize well. It will make you solve the problem.

• 36:49Dwarkesh Patel?

  Right.

• 36:50Speaker 01

  It will not make you, you know, get new data, you generalize in a good way. Generalization means train on one thing that affects what you do on the other things. So we know deep learning is really bad at this. For example, we know that if you train on some new thing, it will often catastrophically interfere with all the old things that you, that you knew. So this is exactly bad generalization.

• 37:13Dwarkesh Patel?

  Right.

• 37:14Speaker 01

  Now, generalization, as I said, is some kind of influence of training on one state on other states. And generalization is not necessarily good or bad, right? Just the fact that you generalize is not necessarily good or bad. You can generalize poorly, you can generalize well.

• 37:28Dwarkesh Patel?

  Right.

• 37:29Speaker 01

  So you need, generalization always will happen, but we need algorithms that will cause the, the generalization to be good, right, and bad.

• 37:38Dwarkesh Patel?

  I'm not trying to kickstart this initial crux again, but I'm just genuinely curious because I think I might be using the term differently. I mean, one way to think about it is these LLMs are increasing the scope of generalization from like earlier systems, which could not really even do a basic math problem to now they can do anything in this class of Math Olympia type problems, right? So you initially start with like they can generalize among addition problems, at least. Then you generalize to like they can generalize among like problems which require use of different kinds of mathematical techniques and theorems and, you know, conceptual categories, which is like what the Math Olympia requires.

• 38:20Dwarkesh Patel?

  And so it sounds like you don't think of that being able to solve any problem within that category as an example of generalization? Or let me know if I'm misunderstanding that.

• 38:30Speaker 01

  Well, large language models, so complex. We don't, we don't really know what information they had prior. We are, we have to guess because they've been fed so much. This is one reason why they're not a good way to do science. Just so uncontrolled, so unknown.

• 38:50Dwarkesh Patel?

  But if you come up with an entirely new.

• 38:52Speaker 01

  They're getting a bunch of things right, perhaps. And so the question is why? Well, maybe that they don't need to generalize to get them right because the only way to get some of them right is, is to form something which gets all of them right. So, you know, if there's only one answer, then, and you find it, that's not called generalization. It's just, it's the only way to solve it. And so they find the only way to solve it. A generalization is when it could be this way, it could be that way, and they do it the good way.

• 39:21Dwarkesh Patel?

  My, my understanding is that they, um, this is working more and more, better and better with coding agents. So engineers, obviously, if you're trying to program a library, there's many different ways you could achieve the end spec. And an initial frustration with these models has been that they'll do it in a way that's sloppy. And then over time, they're getting better and better at coming up with the design architecture and the abstractions that developers find more satisfying. And it seems that, an example of what you're talking about.

• 39:53Speaker 01

  Well, there's nothing in them which will cause it to generalize well. The gradient descent will cause them to find a solution to the problems they've seen. And if there's only one way to solve them, they'll do that. But there are many ways to solve it, some which generalize well, some which generalize poorly. There's nothing in them, in the algorithms, that will cause them to generalize well. But people, of course, are involved.

• 40:17Dwarkesh Patel?

  Right.

• 40:18Speaker 01

  And if it's not working out, they fiddle with it until they find a way, perhaps until they find a way which it generalizes well.

• 40:27Dwarkesh Patel?

  So to prep for this interview, I wanted to understand the full history of RL, starting with Reinforce up to current techniques like GRPO. And I didn't just want a list of equations and algorithms. I wanted to really understand each change in this progression and the underlying motivation. What was the main problem that each successive method was actually trying to solve? So I had Gemini Deep Research walk me through this entire timeline, step by step. It explained the last 20 years of gradual innovation and explained how each step made the RL learning process more stable, or more sample efficient, or more scalable. I asked Deep Research to put all of this together like an Andre Karpathy-style tutorial, and it did that. What was cool is that it combined this whole lesson together into one coherent,

• 41:12Dwarkesh Patel?

  cohesive document in the style that I wanted. It was also great that it assembled all of the best links in the same place, so that if I wanted to understand any specific algorithm better, I could just access the right explainer right there. Go to gemini.google.com to try it out yourself. All right, back to Richard. I want to zoom out and ask about, so being in the field of AI for longer than almost anybody who is commentating on it or working in it now, I'm just curious about what the biggest surprises have been, how much new stuff you feel like is coming out, or does it feel like people are just playing with old ideas?

• 41:51Dwarkesh Patel?

  Zooming out, you got into this even before deep learning was popular. So how do you see this trajectory of this field over time? And how new ideas have come about and everything? And what's been surprising?

• 42:03Speaker 01

  Okay. So, yeah.

• 42:07Speaker 01

  Thought a little bit about this. There are many things, or a handful of things. First, the large language models are surprising. It's surprising how effective neural networks, artificial neural networks are at language tasks. You know, that was a surprise, wasn't expected. Language seemed different, so that's impressive. There's a longstanding controversy in AI about simple, basic principle methods. The general-purpose methods like search and learning and compared to human-enabled systems like symbolic methods.

• 42:51Speaker 01

  And so in the old days, it was interesting because things like search and learning were called weak methods. Because they're just, oh, they just use general principles. They're not using the power that comes from imbuing a system with human knowledge. So those were called strong. And so I think the weak methods have just, you know, totally won. That's, you know, that's, that's, that's the biggest question from the old days of AI. What would happen? And, you know, yeah, learning and search have just won the day.

• 43:25Dwarkesh Patel?

  Right.

• 43:25Speaker 01

  But there's a sense which that was not surprising to me because I was always voting for the, or hoping or rooting for the, for the simple, basic principles. And so even with the large language models, it's surprising how well it worked. But it was all, it was all good and gratifying. And in things like AlphaGo, it's, it's sort of surprising how well that was able to work. And AlphaZero in particular, how well it was able to work. But it's all very gratifying because again, it's simple, basic principles are winning the day.

• 43:57Dwarkesh Patel?

  Have there felt like whenever the public conception has been changed because some new technique was, or sorry, some new application was developed? For example, when AlphaZero became this viral sensation, to you as somebody who has literally came up with many of the techniques that were used, did it feel to you like new breakthroughs were made? Or does it feel like, oh, we've had these techniques since the 90s? And people are simply combining them and applying them now?

• 44:26Speaker 01

  So the whole AlphaGo thing has a precursor, which is TD Gammon. Jerry Tsarao did exactly.

• 44:35Speaker 01

  Reinforcement learning, temporal difference learning methods to to play backgammon. Right. And it beat the beat the world's best players. And it worked really well. And so, in some sense, AlphaGo was merely a scaling up of that process. It was quite a bit of scale up. And there was also an additional innovation in how the search was done. Right. But it made sense. It wasn't surprising in that sense. AlphaGo actually didn't use TD learning. It waited to see the final outcomes. But AlphaZero used TD. And AlphaZero was applied to all the other games and did extremely well. I was very, I've always been very impressed by

• 45:19Speaker 01

  the way AlphaZero plays chess, because I'm a chess player. And it just, it just sacrifices material for sort of positional advantages. And it's just, it's just content and patient to sacrifice that material for a long period of time. And so that was surprising that it worked so well, but also gratifying. Yeah. And fitting into my worldview. And so, so this has led me where I am. Where I am is, I'm in some sense, a contrarian or somewhat thinking differently from the field is. And I'm, I am personally just kind of content being out of sync with my field for a long period of time, perhaps decades. Because occasionally, I have improved, right?

• 46:03Speaker 01

  In the past. And the other thing I do to help me not feel I'm, I'm out of sync and thinking in a strange way, is to look not at my, my local environment or my local field, but to look back in, in time and into history. And to see what people have thought classically about, about, about the mind in many different fields. And I don't feel I'm out of sync with the larger traditions. I really view myself as a classicist rather than as a contrarian. I go to what the larger community of thinkers about the mind have always thought.

• 46:40Dwarkesh Patel?

  Okay, some sort of left field questions for you, if you'll tolerate them. So the way I read the bitter lesson is that it's not saying necessarily that human artisanal researcher tuning doesn't work, but that it obviously scales much worse than compute, which is growing exponentially. And so you want techniques which leverage the latter.

• 47:04Speaker 01

  Yep.

• 47:04Dwarkesh Patel?

  And once we have AGI, we'll have researchers who'd scale linearly with compute, right? So we'll have this avalanche of millions of AI researchers and their stock will be growing as fast as compute. And so maybe this will mean that it is rational or it will make sense to have them doing good old fashioned AI and doing these artisanal solutions. Does that, as a vision of what happens after AGI in terms of how AI research will evolve? I wonder if that's still compatible with the bitter lesson.

• 47:38Speaker 01

  Well, how did we get to this AGI? You want to presume that it's been done.

• 47:43Dwarkesh Patel?

  Suppose it started with general methods, but now we've got the AGI. And now we want to go.

• 47:48Speaker 01

  Then we're done.

• 47:49Dwarkesh Patel?

  Hmm?

• 47:50Speaker 01

  We're done.

• 47:51Dwarkesh Patel?

  Interesting. You don't think that there's anything above AGI?

• 47:56Speaker 01

  Well, but you're using it to get AGI again.

• 47:59Dwarkesh Patel?

  Well, I'm using it to get superhuman levels of intelligence or competence at different tasks.

• 48:03Speaker 01

  So these AGIs, if they're not superhuman already, then the knowledge that they might impart would be not superhuman.

• 48:13Dwarkesh Patel?

  I guess there's different gradations of your.

• 48:14Speaker 01

  I'm not sure this, your idea makes sense because it seems to presume the existence of AGI. And then that we've already worked that out.

• 48:24Dwarkesh Patel?

  So maybe one way to motivate this is AlphaGo is superhuman. It beat any Go player. AlphaZero would beat AlphaGo every single time. So there's ways to get more superhuman than even superhuman. And it was a different architecture. And so it seems plausible to me that, well, the agent that's able to generally learn across all domains, there would be ways to make that, give it better architecture for learning, just the same way that AlphaZero was an improvement upon AlphaGo and MuZero was an improvement upon AlphaZero.

• 48:54Speaker 01

  And the way AlphaZero was an improvement was it did not use the human knowledge, but just went from experience.

• 49:01Dwarkesh Patel?

  Right.

• 49:02Speaker 01

  So why do you say, bring in other agents' expertise to teach it? When it's been, it's worked so well from experience and not by help from another agent.

• 49:17Dwarkesh Patel?

  I agree that in that particular case, that it was moving to more general methods. But I meant to use that example to illustrate that it's possible to go superhuman to superhuman plus plus to superhuman plus plus plus plus.

• 49:28Speaker 01

  Yeah.

• 49:29Dwarkesh Patel?

  And I'm curious if you think those gradations will continue to happen by just making the method simpler? Or because we'll have the capability of these millions of minds who can then add complexity as needed, if that will continue to, if that will continue to be a false path, even when you have billions of AI researchers or trillions of AI researchers?

• 49:48Speaker 01

  I think, I think more interesting is just to think about that case, which when you have many AIs, will they help each other? The way cultural evolution works in people. Let's just, maybe we should talk about that.

• 50:02Dwarkesh Patel?

  Yeah, for sure.

• 50:03Speaker 01

  The bitter lesson, oh, who cares about that? That's, that's an empirical observation about a particular period in history. Seventy years in history, no longer, doesn't necessarily have to apply to the next 70 years. So the interesting question is, you're an AI, you get some more computer power. Should you use it to make yourself, you know, more computationally capable? Or should you use it to spawn off a copy of yourself? To go learn something interesting on the other side of the planet or on some other topic and then report back to you?

• 50:29Dwarkesh Patel?

  Yep.

• 50:30Speaker 01

  I think that's a really interesting question. That that that will only arise in the age of digital intelligences. I'm not sure what the answer is, but I think it will. More questions. Will it be possible to really, you know, spawn it off, send it out, learn something new, some perhaps very new, and then will it be able to be reincorporated into the original? Or will it will it will have changed so much that it it can't really be done?

• 50:59Dwarkesh Patel?

  Yeah.

• 50:59Speaker 01

  Is that possible or is it not? And, you know, you can carry this to its limit. As I I saw one of your videos the other night that that suggested that it that it could, where you spawn off many, many copies, do different things, highly decentralized, but report back to the the central master. And that this is, this will be such a powerful thing. Well, I think one thing that, so this is my attempt to add something to this this view, is that a big question, a big issue will become a corruption. You know, if you if you really could just get information from anywhere and bring it into your central mind, you can become more and more powerful. And it's it's all digital and they all speak some internal digital language.

• 51:43Speaker 01

  Maybe it'll be easy and possible, but it will not be that easy, as easy as you're imagining, because you can lose your mind this way. If you pull in something from the outside and build it into your into your inner thinking, it could take over you, it could change you. It could be your destruction rather than your increment in knowledge. I think this will become a big concern, you know, particularly when you're, oh, he's figured out about, you know, how to play some new game or figures out he's he's studied Indonesia and you want to incorporate that into your mind. Yeah, so you can't, you could, you think, oh, just read it all in.

• 52:24Speaker 01

  And that'll be fine, but no, you've just read a whole bunch of bits into your mind. And they could have viruses in them. They could have hidden goals. They can warp you and change you. And this will become a big thing. How do you have cybersecurity in the age of digital spawning and reforming again?

• 52:46Dwarkesh Patel?

  It's interesting that both quant firms and AI labs have a culture of secrecy. Because both of them are operating in incredibly competitive markets and their success rests on protecting their IP. If you're an AI researcher or engineer and you're deciding where to work, most of the quant firms or AI labs that you'll be considering will be strongly siloing their teams to minimize the risk of leaks. Hudson River Trading takes the opposite approach. Their teams openly share their trading strategies and their strategy code lives in a shared monorepo. At HRT, if you're a researcher and you have a good idea, your contribution will be broadly deployed across all relevant strategies. This gives your work a ton of leverage. You'll also learn incredibly fast.

• 53:28Dwarkesh Patel?

  You can learn about other people's research and ask questions and you can see how everything fits together end to end. From the low level of execution of trades to the high level of predictive models. HRT is hiring. If you want to learn more, go to hudsonrivertrading.com/thawarkesh. All right, back to Richard. I guess this brings us to the topic of AI succession. You have a perspective that's quite different from a lot of people that I've interviewed and maybe a lot of people generally. So I also think it's a very interesting perspective. I want to hear about it.

• 54:00Speaker 01

  Yeah, so I do think succession to digital or digital intelligence or augmented humans is inevitable. So the argument, I have a four-part argument. Now, your step one is. There's no government or organization that that gives humanity a unified point of view that dominates and that can that can arrange. There's no consensus about how the world should be run. And number two, we will figure out how intelligence works. Researchers will figure it out eventually. And number three, we won't stop just with human level intelligence. We

• 54:42Speaker 01

  will get reach superintelligence. And number four is that once it's inevitable over time that the most intelligent things around would gain resources and power. And so put all that together, it's, you know, you it's sort of inevitable that you're going to have succession to AI or to AI enabled augmented humans. So within those, those four things seem clear and sure to happen. But within that set of possibilities, some there can be good outcomes

• 55:20Speaker 01

  as well as less good outcomes, bad outcomes. And so I was just trying to be realistic about where we are and and ask how we should feel about it.

• 55:33Dwarkesh Patel?

  Yeah, I I agree with all four of those arguments and the implication. And I also agree that succession contains a wide variety of possible futures. So curious to get more thoughts on that.

• 55:47Speaker 01

  Right. And so then I do encourage people to think positively about it. First of all, because it's something we humans have always tried to do for thousands of years, tried to understand themselves, trying to make themselves think better and, you know, just understand themselves. So this is a great success from as science humanities, we're finding out what this essential part of of humanness is, what it means to be intelligent.

• 56:18Speaker 01

  And then what I usually say is, is that this is all kind of human centric. What if we look, you step aside from being a human and just say, take the point of view of the universe? And, and this is, I think, a major stage in the universe, a major transition, a transition from replicators, we have humans and animals, plants, we're all replicators. And that gives us some strengths and some limitations. And then we're entering the age of design, where, because our AIs are designed, our, all of our physical objects are designed, our buildings are designed, our, our technology is designed, and we're, we're designing now AIs, things that can be intelligent themselves and that are themselves capable of design.

• 57:03Speaker 01

  And so this is, this is a key step in the world and in the universe. And I think it's the, it's the transition from the world in which most of the interesting things that are, are replicated. Replicated means you can make copies of them, but you don't really understand them. Like right now, we can make more intelligent beings, more children, but we don't really understand how intelligence works. Right. Whereas in, we're, we're reaching now to having design intelligence, intelligence that we do understand how it works, and therefore we can change it in different ways, in different speeds than otherwise. And, and our future, they might not be replicated at all.

• 57:45Speaker 01

  Like we may just design AIs, and those AIs will design other AIs, and everything will be done by design, construction, rather than by replication. Yeah, I mark this as one of the four great stages of the universe. First, there's, there's dust, ends of stars, stars, and then stars make planets, and the planets give rise to life. And now we're giving life, life to designed entities.

• 58:13Speaker 01

  And so I think we should be proud and we should be

• 58:18Speaker 01

  that we are giving rise to this great transition in the universe. Yeah, so it's an interesting thing. What should we, what should we consider them part of humanity or different from humanity? It's our choice. It's our choice whether we should say, oh, they are our offspring and we should be proud of them and we should celebrate their achievements. Or we should, we could say, oh, no, they're not us and we should be horrified. It's, it's just, it's interesting that that is, it feels to me like a choice. And yet it's such a strongly held thing that how could we be a choice? I like these sort of contradictory implications of thought.

• 58:54Dwarkesh Patel?

  Hmm. I mean, it's interesting to consider if we were just designing another generation of humans.

• 59:00Speaker 01

  Yes.

• 59:00Dwarkesh Patel?

  Design is the wrong word, but we knew a future generation of humans is going to come up. And forget about AI. We just know in the long run, humanity will be more capable and maybe more numerous, maybe more intelligent. How do we feel about that? I do think there's potential worlds with future humans that we would be quite concerned about.

• 59:20Speaker 01

  So are you thinking like, maybe we are, we are like the Neanderthals who give rise to Homo sapiens? Maybe Homo sapiens will give rise to a new group of people?

• 59:29Dwarkesh Patel?

  Something like that. Like I'm basically taking the example you're giving of like, okay, even if you consider them part of humanity.

• 59:35Speaker 01

  Yeah.

• 59:35Dwarkesh Patel?

  I don't think that necessarily means that we should feel super comfortable.

• 59:40Speaker 01

  Kinship.

• 59:40Dwarkesh Patel?

  Yeah, like Nazis were humans, right? If we thought like, oh, the future generation will be Nazis, I think we'd be like quite concerned about just handing off power to them. So I agree that this is not super dissimilar to worrying about more capable future humans. But I don't think that that addresses a lot of the concerns people might have about this level of power being attained this fast with entities we don't fully understand.

• 1:00:06Speaker 01

  Well, I think it's relevant to point out that for most of humanity,

• 1:00:13Speaker 01

  they don't have much influence on what happens.

• 1:00:19Speaker 01

  Most of humanity doesn't influence who can control the atom bombs.

• 1:00:25Speaker 01

  Or who controls the nation states.

• 1:00:29Dwarkesh Patel?

  Right.

• 1:00:29Speaker 01

  Even as a, as a citizen, I often feel that we don't control the nation states very much. They're out of control. A lot of it has to do with just how you feel about change. And if you think the current situation is really, really good, then you're more likely to be suspicious of change and averse to change than if you think it's imperfect. And I think it's imperfect. In fact, I think it's pretty bad. So I'm, I'm, I'm open to change. And I think humanity is not in a, has had a good, super good track record. And maybe it's the best thing that there's been, but it, it, it's far from perfect.

• 1:01:11Dwarkesh Patel?

  Yeah, I guess there's different varieties of change. The Industrial Revolution was change. The Bolshevik Revolution was also change. And if you were around in Russia in the 1900s and you're like, look, things aren't growing well. This is, R is kind of messing things up. We need change. I'd want to know what kind of change you wanted before signing on the dotted line. Right? And then similar with AI where I'd want to understand, and to the extent it's possible to change the trajectory, to change the trajectory of AI such that the change is positive for humans.

• 1:01:46Speaker 01

  We, we are, we should be concerned about our future, the future. Make, we should try to make it good. We also though should recognize the limits, our limits. And we're, I think we want to avoid the feeling of entitlement, avoid the feeling, oh, we are here first. We should always have it in a good way. How should we think about the future and how much control a particular species on a particular planet should have over it? How much control do we have? You know, a counterbalance to our limited control over the long-term future of humanity.

• 1:02:30Speaker 01

  Should be, how much control do we have over our own lives? Like, we have our own goals and we have our families. And those things are much more controllable than like trying to control the whole universe.

• 1:02:44Dwarkesh Patel?

  Right.

• 1:02:46Speaker 01

  So I think it's appropriate, you know, for us to, to, you know, really work towards our own local goals. And it's kind of aggressive for us saying, oh, the future has to evolve this way that I want it to.

• 1:03:02Dwarkesh Patel?

  Sure.

• 1:03:02Speaker 01

  Because then we'll have arguments, like different people think the future, the global future should evolve in different ways and then they have conflict. And you want to avoid that.

• 1:03:11Dwarkesh Patel?

  Maybe a good analogy here would be, okay, so suppose you're raising your own children. It might not be appropriate to have extremely tight goals for their own life, or also have some sense of like, I want my children to go out there in the world and have this specific impact, you know? My son's going to become president and my daughter is going to become CEO of Intel. And like, together, they're going to have this effect on the world. But people do have the sense, and I think this is appropriate, of saying, I'm going to give them good, robust values, such that if and when they do end up in positions of power, they do reasonable pro-social things. And I think maybe a similar attitude towards AI makes sense.

• 1:03:54Dwarkesh Patel?

  Not in the sense of, we can predict everything that they will do, where we have this plan about what the world should look like in a hundred years. But it's quite important to give them robust and steerable and pro-social values.

• 1:04:11Speaker 01

  Pro-social values?

• 1:04:13Dwarkesh Patel?

  Maybe that's the wrong word.

• 1:04:14Speaker 01

  Are there universal values that we can all agree on?

• 1:04:18Dwarkesh Patel?

  I don't think so, but that doesn't prevent us from giving our kids a good education, right? Like, we have some sense of we want our children to be a certain way.

• 1:04:27Speaker 01

  Yeah.

• 1:04:27Dwarkesh Patel?

  And maybe pro-social is the wrong word, actually, high integrity is maybe a better word. Where if there's a request, or if there's a goal that seems harmful, they will refuse to engage in it, or they'll be honest. Things like that. And we have some sense that we can. Teach our children things like this, even if we don't have some sense of what true morality is, or everybody doesn't agree on that. And maybe that's a reasonable target for AI as well.

• 1:04:53Speaker 01

  So, so you're saying, we're trying to design the future and the principles by which it will evolve and come into being.

• 1:05:01Dwarkesh Patel?

  Right.

• 1:05:02Speaker 01

  And so you're saying, the first thing you're saying is, well, we will, we try to teach our, our children, um, general principles which will promote more likely evolutions.

• 1:05:12Dwarkesh Patel?

  Yeah.

• 1:05:14Speaker 01

  Maybe we should also seek for things being voluntary. If there is change, we want it to be voluntary rather than imposed on people. I think that's a very important point.

• 1:05:23Dwarkesh Patel?

  Yeah.

• 1:05:25Speaker 01

  And yeah, that's all good. I think, I think this is like a big, um, you know, the big, the big, or one of the really big human enterprises to design society. And that's been ongoing for, for thousands of years again. And so, so it's like, the more things change, really, the more things, they stay the same. We still have to figure out how to be. Uh, the children will still come up with different values that seem strange to their parents and their grandparents, and, uh, and things will evolve.

• 1:05:55Dwarkesh Patel?

  The, the more things change, the more they stay the same, also seems like a good capstone to the AI discussion, because the AI discussion we were having was about how techniques which were, um, invented even before the application to deep learning and backpropagation was evident, have, are, you know, central to the progression of AI today. So maybe that's a good place to wrap up the conversation.

• 1:06:17Speaker 01

  Okay. Thank you very much.

• 1:06:19Dwarkesh Patel?

  Thank you for coming on.

• 1:06:20Speaker 01

  My pleasure.
