In short

Richard Socher argues that scientific progress has slowed because knowledge has fragmented into thousands of subfields, making it hard to recombine insights. He claims AI will restart progress by enabling “recursive self-improvement” (AI improving AI) and by acting as a “language” for complex systems, letting researchers “read biology” less and “write biology” more. He outlines his book The Eureka Machine and Recursive’s approach using four pillars: human knowledge + language models, measurements, simulations, and robotic automation/verification, plus an agent swarm of scientists.

Guest background

Richard Socher is a highly cited AI researcher; he’s the founder/leader behind Recursive (raised $650M) and previously worked as chief scientist at Salesforce. He co-developed protein language model work (ProGen) and is associated with startups like ProFluent.

Key claims

Next-token prediction learns domain “world models” (including geography and protein structure correlations). Hallucination can be useful for exploring novel proteins if verified with real data. AI will accelerate coding/math and then biology, but medical timelines still require trials.

Notable examples

antibiotics vs unresolved viruses/cancer; protein sequence/3D folding correlations; “driving south from Dresden/New York” analogy; ProGen and ProFluent’s protein designs; AI-driven drug cocktails and RNA sequences; AI economist simulation with taxation/recovered a known optimal-tax result.

0:00Anything you can simulate, AI will solve. But before you know it, you're in this recursive self-improvement loop. And we believe that that will be a great unlock. Boy, are we far away from the true upper bounds of any of the spaces of intelligence. And there's still so much further that AI can go. Hi, I'm Matt Turck. Welcome back to the Matt Podcast. My guest today is Richard Socher, one of the most cited researchers in AI. and now at the center of the term everyone in AI is suddenly talking about. Recursive self-improvement. AI that makes better AI. Richard just raised$650 million for Recursive, a company built to do exactly that.

0:39And his new book, The Eureka Machine, is a fascinating blueprint for how AI and RSI are about to revolutionize science. Please enjoy my conversation with the always excellent Richard Saussure. Hey Richard, welcome back. Great to be back. Thanks for having me. All right. So lots to catch up on. We're going to talk about recursive intelligence. We're going to talk about recursive the company. But first and foremost, and most importantly, perhaps, we're going to talk about your new book entitled The Eureka Machine, which I read with great interest and would strongly recommend coming out in a couple of weeks, I believe.

1:18The book opens with a premise that I think a lot of people find surprising and shocking, which is this claim that scientific progress has slowed down, which feels counterintuitive given the number of researchers we have around the world and the sheer amount of money that goes into the space. So why is that? Yeah, it's a somewhat surprising fact. And you may argue clearly not. We're making so much little progress on so many different things. But when you think about, you know, how much progress have we made on antibiotics? Like bacterial infections went from like a death sentence and the plague to like a nuisance.

1:56Like we now have antibiotics for almost all the different bacteria and we truly solved that. And like we have clearly not solved viruses or cancer the same way we solved bacterial infections. When you think about foundational novel things like E equals MC squared and general relativity, we clearly have not made progress on many theories and physics either when it comes to such foundational things that then literally led to nuclear energy and fusion and fission and other kinds of research that could be conceptually done. And so a lot of the fields have kind of gone through from we understood some foundational pieces to we can now do a lot of engineering, but they've also split up into thousands of different subfields.

2:41It is almost impossible nowadays to be the sort of general genius that can dabble in all of these different fields because each field takes years and years and years to get really deep into. And so what we found is that as there are more and more subfields and niches, it's actually hard to have enough people in each of these subfields. And Stanislav Lem and others have talked about that and predicted that that will be a big part of why we're slowing down. Yeah, you have a great expression. you talk about how we evolve from a body of knowledge to a labyrinth of knowledge 34 000 journals that i might as well have no trespassing signs that's right yeah it's so hard to like even understand all the lingo and i've sort of gone through this myself first when i started studying linguistics and computer science but now that i'm sort of trying to study and have studied now over the last few years sort of on the side biology it's like man every time you have a conversation with biologists like 10 sentences in they're just telling you so many abbreviations and terms that you're not familiar with that most people after a while just space out and so it's really hard to describe and explain very complex deep fields to someone who hasn't been in them you also mentioned that there is some level like kind of like social human element to this where in academia, you're not necessarily encouraged to take risks.

4:05And that goes to your own experience as well. Yeah, 100%. Like people often, you know, the way careers work is you want to be kind of novel, but if you're too novel, if you're too far out there, then your papers will get rejected. And that certainly happened to me a lot in the early days, like 2010 of neural networks for natural language processing, where the majority of my first couple of papers got rejected from NLP conferences when they got accepted in like some small sub niches and subgroups. I still remember the first sort of deep learning workshops, workshop at NIPS back in the day, now NeurIPS, that was basically like 30, 40 people, all the now super famous folks.

4:48But it's just like a couple of us renegades who thought that this would clearly be the right way of going about it. And we came from different directions, like feature engineering seemed like not the right path to doing things. Feature learning was a big part of what got us started. Some were neuroscience inspired. And it was, again, that sort of combination of different fields that was, you know, at that intersection where it's interesting, but also often hard to publish well in the beginning. Okay, great. So to play it back is fundamentally that idea that there is too much knowledge everywhere.

5:20where even people within the field are not necessarily encouraged to go super far and to come up with crazy ideas. And the challenge is to bring everything back together. So the Renaissance man, so to speak, had only a small body of knowledge and therefore were able to come up with cross-disciplinary insights, but this is no longer possible, right? That's exactly right. Even like a good example, again, in biology is that you study not all of biology anymore. You study either biology at the cell level or the tissue sort of medical level or the biochemistry level or the protein level. And if you ask a PhD in biology about like a deep question in one of the other layers, they often don't know either.

6:00Great. All right. So the premise of the whole book is that AI is about to usher or in the process of ushering a whole new paradigm of scientific progress. So just walk us through the high-level idea. A little idea is that when, you know, like science has gotten really good at understanding smaller and smaller pieces, but to bring them back up and bring them together, we actually have to use AI. And AI is kind of what Calculus did for physics. AI will do for biology in the sense that it'll help us weave back together lots of very complex pieces that build these complex systems that then have certain properties.

6:44So concretely, for instance, your microbiome or the brain, they have so many different pieces. And we actually understand many of the individual neurons. So, okay, this neuron is at these synapses and this is how it fires and so on. And this is the chemistry, which often people still ignore in a lot of neural models and so on. But then as we put more and more of them together, we stop understanding why the whole brain can now have a thought or do certain things. And I think AI is the perfect language, the perfect way of thinking about some of these complex systems and has the ability to also exhibit sometimes patterns that are almost hard for us to then understand.

7:23But of course, it's always easier to understand and study a neural network than it is to study the original biological system. And so I think when you put all these together and I'll talk about sort of the details of the Eureka machine and its four columns and so on, and you look at the data, you look at sort of different fields, everything from physics, chemistry, biology, neuroscience, medicine, economics, astrophysics, and so on. You look at all of these levels and you see so many small improvements in all of them that can help you extrapolate that AI will usher in this new age. There's still a good number of people out there that think of generative AI as a next token predictor, as a chatbot, as something for language.

8:08Here, the claim is very different. It's predicting protein structures. Why is the technology that's good at being the best chatbot in the world also good at scientific discovery? I think it's quite counterintuitive, as I'm glad you asked, because if you ask a biologist if we'll have a model that can predict something as complex as aging or like general, like different cancers and so on, they'll say, no, this is like decades out. And in a similar fashion, 10, 20 years ago, natural language processing researchers would have told you that it is impossible to build one neural network that could answer any and all kinds of questions.

8:51In fact, you can find this online on Open Review. My paper where I described prompt engineering, like one neural network that you can just prompt with any kind of questions called Deca NLP, the paper. um that paper was wildly widely rejected um by the like basically all the reviewers and the the area chair and so on as just like completely useless like too crowded like made no sense not even humans have one system to answer all these different kinds of questions and so it was like so like something that's so obvious now that people like you can't even invent prompt engineering because it's so obvious it was like such a non-obvious thing to the field and so So we've seen that time and time again throughout different fields.

9:37But now I think once you showed that we didn't have to actually truly understand and have perfect rules for every single aspect of translation or question answering, we will see similar things and have seen already in, for instance, the language of proteins. So you have just sequences of amino acids. No human has been sort of evolutionarily trained and has learned to speak the language of proteins. But just like the language of natural language of English and so on, AI doesn't really care if it's English or a sequence of amino acids. And so you can now generate completely new kinds of proteins like you can generate new kinds of sentences that have never been in that combination in the training data.

10:22And I think, you know, when you now apply similar ideas to chemistry and even lower levels, such as molecules, you'll see that that idea that you have very complex systems that with a lot of data can then make very useful predictions that explore the overall space better and better than any human could have manually. that helps you then say, okay, like this is much more. This next token prediction is such a beautiful yet simple idea that incorporates knowledge about almost any domain. Because there is a concept of world model, and I realize that term is as a precise meaning that I may not be using precisely here, but a concept of world model that's built into what enables the system to predict the next token.

11:13I think in the book you have a lovely example about driving south from Dresden. Maybe unpack that. Yeah, so next token prediction, like why is it so powerful? Imagine you could try to have a model where you understand the world's geography and where every city is. And here we're in New York, so maybe I'll use a New York example. Driving south to New Jersey. For example, yeah, to Princeton or somewhere or north to Boston. And so you basically, just by trying to predict the next token, you will stumble upon sentences where someone somewhere wrote like, oh, I was in New York and I was driving north too, right?

11:49And now it might be Yale, but maybe more likely it's Boston, right? And the more likely it is, probably the bigger the city is. And so you now incorporate by trying to predict the next word in that one sentence, I was in New York driving north too. That next token being Boston, now you predicted something about geography and locations of cities. And so by virtue of doing that billions and billions of times, in fact, trillions of times nowadays, like basically as much data as you can, you actually incorporate knowledge about geography in that. And what we're seeing very similar fashions, a lot of people are familiar with protein folding.

12:26When proteins fold, some proteins are actually closer to each other in 3D space than they would be in a sequence of these folded proteins. and it turns out that you can analyze the neural network that was trained to do next token prediction and you see that indeed the ones that are closer in physical space after being folded the neural network just by doing next token prediction is also like has those correlations and and so we basically know that large neural nets trained on very large specific domains will incorporate the knowledge of that domain just by trying to predict the next token quote-unquote in sequence and token for for the non-technical folks means it can mean an english word can mean a subphrase of an english word just like a sequence of characters that together make up a word but a token can also mean a protein it can also mean a piece of a few pixels in an image or in a video or in a piece of sound so everything can be kind of tokenized basically discretized into a set of vocabulary tokens that are then able to be predicted.

13:32By the way, if I may, you know, you're talking to an extraordinarily accomplished AI researcher when you sense of East Coast geographies at what's south of New York is Princeton and what's north of New York is Yale. Is there a part of the analogy that breaks down if you have this implied idea that across physics and bio and what have you, this sort of language, does that truly translate as an analogy? So there are clearly some places where it feels weird, like it feels oversimplified. And you could clearly say like all models are wrong, but some are useful. And that's also true. Like we know proteins aren't just sequences.

14:11They have a 3D structure, for example. But it's surprising how far this analogy is being able to be pushed. Like even in chemistry, you know, you have like various loops within molecules, but somehow if there's just like a standard way of describing molecules as a sequence, as a string, and using that is very helpful for a variety of different aspects of chemistry too. So yes, it's oversimplified. Yes, all models are wrong, but this particular set of models is quite useful for all the different sciences. And then of course, you can go into arguing, but how truly novel can ideas be from some of these models?

14:48And the truth is that like almost all of science, we stand on the shoulders of giants And just exploring the recombination, the clever combination of all the different ideas that are already out there will lead to incredible progress. Like we have a lot of the foundational pieces figured out in small pieces, like the smaller sort of subsets. But to weave them back together will lead to incredible progress, especially in biology. And then you can also explore how well these models can create novel ideas. And there we also have real examples of researchers having had an AI ideate. And then a few months later, people publishing this paper with essentially the same idea.

15:35Jeff Kluhner of our co-founders at Recursive has tweeted about several such things happening where he had novel evolutionary ideas or evolutionary algorithms create ideas that later have then be published by also people. So clearly the novelty threshold has been met in several cases. Now, will it derive like a completely novel way of looking at the universe, maybe be able to disprove or prove any of the many string theories that are out there and things like that? There's still some research that has to be done, But I'd argue that, you know, we can with existing technology and giving it more data and more compute, we can already cure a lot of diseases.

16:16We can already cure many of the aspects of aging. We can already build better fusion like reactors and systems. We can already create new materials. You can already help with economic questions of how much to tax or subsidize certain populations if you have a certain objective or reward that you're looking for to achieve inside your economy. All of these things are already within our grasp. I was going to visit that idea later, but since we're on it and it's such a fascinating concept and so central to the whole discussion, let's double click on it. So indeed, as we talked about recursive self-improvement, RSI, one of the big questions has been creativity and the ability to sort of think out of the box.

17:06And, you know, you also hear people talk about Moves 37, which was the move in Go that nobody expected and that enabled the deep mind model to beat the least heat all. What is the mechanism by which this can or cannot happen? Do we understand that or is precisely the fact that we do not understand it the reason why we don't think AI can be as creative as it could be? I think we can basically predict where AI will certainly have superhuman capabilities. And those are all scenarios and all domains where we can either have a simulation and or a verification tool. any kind of domain that we can simulate will basically result in a world where the eye can essentially infinitely many times experiment inside that simulation and assuming the simulation doesn't take you know years to run every time you want something useful from it you then know that you can solve the problems in that domain and so all the games i was never that surprised that AI will eventually fairly soon be better than us in games that are especially the games that are perfectly visible.

18:27They don't have hidden variables, like you don't know other people's cards. Like in chess and Go, you see everything and it's all on the board. Now, there were too many combinations in the board to just do brute force kind of winning of those games. But if you have enough training data, the AI can learn the intuitions also behind it by playing many, many games. And in this case, in particular, it's even easier because the eye can play against itself. And that idea to play against yourself is also a big part of open-endedness and recursive self-improvement that we've applied. And I can talk about rainbow teaming and security and safety research, for example, of LLMs also.

19:06But just to go back, simulations, anything you can simulate, the eye will solve. Now, what else can be simulated that's interesting and can be verified that's useful? Math. math is like going to change massively within the next few years at terence tau and the most famous and most sort of frontier mathematicians already fully aware of it the whole field will change just like the field of ai has changed and a lot of sort of skills that used to be useful where you manually feature engineer and then you manually architecture engineer and you manually do these things like are not that useful anymore that will be true for a lot of mathematics also and so i think uh that's a great sort of situation if you cared about solving as many things, proving as many theorems as possible in math.

19:51It's not a great thing if you're just love the sort of pursuit of math for intellectual sake and for fun. And we'll actually see that play out in many different ways. You know, chess is now more popular despite being dominated by AI, if you wanted to. I think most sports, intellectual and physical in the future, will probably benefit. I don't know if you saw the robot running really funny in the Chinese Olympics recently. My hunch is humans will try to see if they can emulate that funky run to then run faster too, because AI in simulations and the like robotic simulations tried many different ways of running and found this weird new way that somehow humans, despite having run all our existence, haven't thought of yet.

20:38Right. And so there will be just like the best chess players and best goal players are better now because they can compete against an almost perfect AI. I think even that will be true for athletes in the future. So I think it will push the field forward. And what's the most powerful thing we can simulate and verify and build verifiers for is programming. Software is eating the world, famously said, I think Mark Andreessen. And so AI is eating software. So now you can basically, one example, a simple example is you can show the picture of a website and you say, make it program such that it looks exactly like that.

21:11Right. And then you can create infinitely many examples like that and then have a perfectly capable AI building front ends for websites. And the truth is you can create all kinds of verifiers like that. And so all of programming will change and that will be a major impact on the entire digital economy, which is the knowledge economy and so on. And then the question is, where does it stop? Well, what things are hard to simulate right now? And that's where it becomes interesting to look at the natural sciences, where we cannot yet perfectly simulate a complex cell, let alone tissues or organs and full humans.

21:45And we do need to collect a lot more data in various robotic forms. And those are essentially the four columns that I talk about in the Eureka Machine 2. You start with human knowledge and LMs. Then the second pillar are all the measurements we can take and more and more of those that we already have. And we should incorporate that into the model. The third thing is a simulation. And the fourth thing, fourth pillar, is essentially robotic process automation to collect even more data and verify whether the inventions really made sense. And on top of those four, you have an agent swarm and a community of scientists.

22:18So we'll definitely unpack that part in a minute. Just going back to, so there's the question of the intuition and creativity, which is one of the unexplored frontier. And then related to what you just said, there's also the big question of generalization. So starting with coding and math that seem to be increasingly conquered domains by AI. You seem to be saying that then there's like the life sciences that could be next. what is your sense for how far we can go in making AI really general? And what is the process to get there? Is that like brute force RL for this domain and then that domain and that domain?

23:02Or is there a more sort of sweeping generalization effort that could be produced? So at Recursive, we are fairly sure that we have to start with AI for AI and then make it really, really good at doing research on creating better AI so that it has the equivalent of 50 ,000 PhDs in terms of knowledge and its own capabilities and only then go after the physical and natural sciences, like physics, chemistry, and biology, especially biology, I think will be most interesting. I do believe that in the next two or three years, while we're focused on recursive self-improvement, also we will have more and more data collection.

23:46Tahoe Therapeutics is a great example. Perillel Bio is another one. I think I mentioned both of them in the book that basically help create much, much more training data. And then when you have, in the case of biology, for instance, you can do these perturbation studies. Like you take a cell, you try to knock out one gene and you see what happens when I knock out this one gene. Or I add this one molecule to it and I see what happens. So if you do many, many perturbation studies, eventually maybe the AI will learn the underlying patterns behind it, just like it learned the underlying patterns of like, oh, I'm in New York and I'm driving north too.

24:22And then predicting Boston, it might be like, oh, I add this molecule to this kind of cell and then I get the output of, you know, and then it's just like it can start to eventually generalize. But we're just nowhere near having enough training data for biology. And so we need organoids. We need eventually all these perturbation studies to come together so that we can then try to build a virtual cell. And then in that virtual cell, the eye can then go and experiment many times. There is another counterintuitive idea in the book that I thought was fascinating, which is that when it comes to AI-based science, hallucination might be a feature rather than a bug.

25:05Can you explain? Yeah, so a lot of folks struggle with hallucinations and models for a long time. especially in the earlier versions of these models. The book, you know, I started thinking and writing the first sort of ideas down like three years ago and had to change a lot of chapters to someone should do to someone has done and let me like talk to them and talk about their startups and whatnot. But I do think hallucinations can be also very helpful for AI when you want it to explore novel kinds of proteins. Like, yes, it can, like every AI can memorize things. Every computer can easily memorize things, right?

25:41But where it's interesting is like, how well can you hallucinate? How reasonable or just outside of the distribution in some interesting way are your predictions, right? And we also know that we can, just like with humans, right? You give them like a certain kind of molecule and their visual cortex goes off into a really different world. Like you can also increase the temperature is what we call it and sort of a term, like a technical term that the AI at the large language model will then. generate tokens that are more and more different to things that has seen before. And so I think hallucinations are in some cases a feature and not a bug.

26:21Of course, when you ask a factual question online to a search engine or an LM, then you want to have it like be correct. And when we know that that's the kind of question you're asking, it's easy to prime them all and say, well, here are search results. That's what u.com does, of course, to like basically take the facts from a real search engine, build four agents, plug them into the prompt, and then the AI will kind of summarize that. And so I think the initially people thought, oh, we need neuro-symbolic reasoning, blah, blah, to do all this. We just needed more examples of don't hallucinate now, like take real facts from a search engine and then mostly summarize those.

27:00And then those like hallucination problems were to a large degree resolved. And then if you want to write a poem for your wife, you don't want it to just look sound like the other poems that are out there you want to create a new one you can also do that and as a funny moment in the book you mentioned that actually a lot of scientific discoveries were made by scientists in the semi-state of hallucination through diseases or otherwise that's right yeah like i mean uh heisenberg and like other physicists and there's all kinds of interesting stories about apps and in some cases also just like actual like mental states that were like eventually quite unhealthy and just psychoses and so on have in some cases pushed the field forward.

27:42All right. So you alluded to some of this, but let's take some of the life sciences as examples just to unpack some of the thinking there. So starting with medicine, the deeper shift that you describe is going from reading biology to writing it. And your own team did that was one of the first teams to do it so do you want to sort of tell us what you guys did and what that means in terms of where science is going yeah i think when i started studying the first time i studied psychology biology was in in high school and i never to be honest loved it back in high school because it's just like memorize these like processes with all of these different pieces you write them out you get an a and then like six months later you mostly forgot about that process.

28:27And so that wasn't that interesting to me. But what's changed in the last few years is that biology is becoming a programmable science. It's becoming an engineering science. And it's often the case, I think, in sort of the transition of different sciences. Once you've understood most of the basic pieces, you now want to learn how to put them together in novel ways such that they are useful for you. And there's like low hanging fruit when a field transitions into that becoming sort of an engineering science. And I think biology is in that state right now where we know, okay, this protein does this but if we change that protein a little bit maybe it can do something else and you can package you know and sometimes uh you can connect different things that you know one piece for instance attaches to a cell but then you can have different loads like connectors to it so once it's attached to the cell you can actually inject something into the cell and now you can recombine these these molecules and so i think that uh like engineering aspect of it i think is truly exciting And the first sort of aha moments for us was, I think, in 2018, when we trained the largest language models for proteins.

Read the full transcript

29:32It's called ProGen. Ali Madani is the first author of that paper. That was back in the day when I was the chief scientist at Salesforce still. And he's since started ProFluent. They've now closed like multi-billion dollar contracts with Eli Lilly at ProFluent, his company, because they've created new kinds of proteins that are, for instance, even better than CRISPR-Cas9. and gene editing and being even more specific and targeted for changing certain genes inside living people potentially and creating new kinds of therapies from that. And so proteins being such an important piece of all the building blocks of life and disease and health, making them programmable will unlock very, very obviously many, many exciting use cases.

30:24And I think you're starting to see this sort of in this recent trial that is making a lot of progress where they basically created a different drug for every different patient in the trial. And this is a first for the FDA too. And more will happen there. It's actually unfortunate how hard it has become in the US and certainly in Europe to run clinical trials. And so a lot of folks are now moving to either China or Australia for their clinical trials. interesting enough in china it's cheaper it's faster but you also have to worry a little bit whether your ip gets sort of sucked into the ether and is gone and in australia they had a clever move where they actually decentralized clinical trials and every hospital can run its own clinical trial so all of a sudden you get competition instead of having one centralized um uh sort of decider on on which clinical trials to run and how to sort them and uh and all of that and so yeah anyway there's not enough people in Australia, so it would be great to get that kind of system happening in the U.S.

31:23too. But yeah, clinical trials will be more and more efficient over time. We'll collect more data and NDI will be able to automate more and more of that. And when you think about the drug discovery and creation life cycle from initial intuition to being available that take, 10 or 15 years, what are we talking about here in terms of accelerating discovery? what realistically what portion of the process does it shave off it's a good question and sort of touches upon uh what some people call the hard takeoff too where some people think once we have RSI and and generally with AI there will be this really hard takeoff and then everything will just happen very quickly and as bullish and excited as I am about AI I'm not a believer in this crazy hard takeoff I think yes things will accelerate but there are certain things that will just require time because of physics and constraints in the real world, such as like long-term trials that you want to know whether people have some issue like three years after the, you know, they stopped taking the drug and things like that.

32:28And so there will be some delays, but the biggest difference is that the whole biomarket and somewhat contrarian take that we have at AIX Ventures too, a lot of folks think that like bio is just a terrible space to invest in because in the past, a lot of drug companies kind of spent eight, 10 years. They finally get, you know, they have to be public because there's not enough late stage bio investors. So they go public with one drug or maybe two drugs in late stage trials, like stage three, and then the stage three trial fails. And then the whole company is dead. Now, what we're seeing, the difference is like we now have companies that instead of having one molecule or drug after eight years in late stage trials, They actually, within six to 18 months, have multiple different drugs in late stage two trials already.

33:21And by the time they'll go public, it'll be with eight plus different drugs that are then also much more likely to succeed because we have better predictive models. So clearly we are living in a moment when AI has become quite controversial, whether that's the job question or the data center question. The number one thing the industry keeps saying as a way to justify why AI is a great thing is AI is going to cure cancer. What is your sense of the reality of that claim and what it's going to take to get there? There's a lot to unpack there. Maybe at a very high level, I think if you care about the outputs of an industry or a company, then you love AI.

34:09If you get paid hourly, you probably hate AI. And so AI in the positive instantiation of this future is a huge force towards more entrepreneurial thinking. If you're an entrepreneur, generally you kind of love AI because it's making your things more efficient. You just get more done. You have to like, you have an unlimited list of things to do if you're a startup founder or just running a company. And to have any, I do many of those things for you just means you can do a lot more. But if you're like basically being told you're training your replacement and you're like all your data is being collected hourly, then you know at some point those hours will end and then the I will just do the thing you just taught it how to do.

34:53And so it's understandable that people, if they have this very unentrepreneurial mindset of just getting paid by the hour and they don't own any equity in creating that IP, then they're understandably unhappy. And then you can go one level deeper and think about, well, what is the impact on jobs? And my theory here, after thinking about this for quite some time, is largely dependent on the elasticity of the demand of the product when its prices go down. And so concretely, for instance, illustrators. Illustrators hate AI. The world needs a certain amount of illustrations. because of AI, you cannot charge 200 bucks anymore for one illustration.

35:39So now any little blog post has illustrations. If your goal was just to see more illustrations in the world that are specific to a text, you love AI. If you got paid 200 bucks for one illustration and now it's worth two cents maybe, you hate it, right? And so the problem was that the demand for illustrations didn't go 1 ,000x when the price went down by 1 ,000x. didn't grow because you just don't need that many illustrations in the world. Now in coding, it was a very different world. Actually, as coding got cheaper and cheaper, you had this famous Jevons paradox that everyone's talking about now.

36:15I think I was the first, at least I didn't see it online for a while. It's like an interesting fact from history. And you actually like the thing got cheaper and cheaper, but we actually used more and more of it. And for coding, that will definitely be the case. And so we're seeing actually more demand for programmers now because they're so much more productive when they use AI. and anyone ultimately could have like dozens of apps on their phone that are unique to that person that are modified in some way and very special. And there's so many other ideas that people didn't explore because it was like, maybe the market wasn't that big, but now that you can just create an app really quickly, why not?

36:49And so I think that is another aspect of jobs. And so go back to cancer. Yes, I do believe actually AI will play a big role in curing multiple cancers. We are seeing trials now where AI is being used to make a specific cocktail of drugs, create specific RNA sequences and so on for the types of cancer. And, you know, each cancer often is also not one like homogenous thing. It has different types of sub cancers in it and so on. And you need to specialize treatments for each person and for the various different forms of the different cancers that you can have. And so all of that is much, much more feasible to be done with AI.

37:31And we're seeing it. Is that precisely the point that cancer is just extremely complex and ultimately a system problem? Exactly. That AI is uniquely equipped to solve? Exactly. So, yeah, it will take some time. And obviously, like, even if AI, let's say, had the perfect molecule and like, okay, for this type of cancer, this is the molecule that came up. Like, and I came up with it, you'd have to still run it through many clinical trials. It'll still take years to come out. So everything in biology just takes longer than it does in software. What else are you optimistic about in that field? Your predictions for the next decade, rare disease cures, organs designed for individual patients, pollution eating synthetic cells.

38:16You cover some of this in the book. What are you most excited about in terms of what may come first? Yeah, I'm excited about all of these things. I think we can design bacteria that eat microplastics. And once there's no more plastics, they just die. I think that would be extremely helpful for the oceans and so on. Obviously, you have to be very, very careful that they don't somehow mutate into eating other things and so on. So when you mess with the environment at large scales, it's important that humans have done that many times. And sometimes it worked out pretty well. Many other cases, maybe not so much, like forests are a good example.

38:49People deal with forests too much. They don't let small forest fires happen. And then they get even bigger because the small ones didn't clear out the underbrush and so on. Everything is a system. Everything is a complex system. And we need AI more and more to do some of that engineering better than we've done in the past. And so I'm excited for at all the different levels. You know, when you look at like how to balance plasma and tokomaks for nuclear fusion, that's already a machine learning control problem. I think we'll have a better handle on that. So sort of at the lowest level of physics, clearly there are more and more materials, more efficient solar cells and solar panels that we can design with AI.

39:29There's companies I've invested in that do that, better batteries, better materials. So we don't need only lithium. We can try to build batteries with more abundant molecules that are easier to get and mine of less pollution. We, especially again in biology, seeing a lot of things. I think it sounds like science fiction and I understand. So the famous saying of like, if you want to know why something doesn't work, ask the experts. I think that that was true in natural language processing and neural nets. And I think it is currently also true for longevity and cancer and other kinds of research for neural nets applied to biology and medicine.

40:08I do think we'll see, we'll make more progress than the most skeptical people think. But we also want to have a heart takeoff again because things do require careful experimentation in medicine. And I'm personally excited for all of these things. I think if you're mostly interested in like making humanity more productive and more efficient and create more outputs and grow, then you're going to love AI. But I also, in some ways, it becomes a philosophical question. And I think you've already, we already observe many sub-civilizations or like, you know, subgroups of people, I mean, and cultures that have essentially off-ramped from progress.

40:50Like if you're living on some beautiful island in Greece, you don't really think about AI. You don't have to think about AI and you just enjoy life. You go fishing and, you know, sometimes there's a storm and things are bad, but most of the time, like the weather is good, the fish are abundant and you just kind of live your life. And so I think there will be different groups of people who will want to off-ramp from civilization progress, right? There's already, you know, people prefer to live way deep in the countryside and never go into the big city and so on. And I think we'll have more of that.

41:23And in some ways, I personally love progress. I think scientific progress especially is what helped humans solve most of the hard problems that were in our biosphere. David Deutsch has a whole section in his book, The Beginning of Infinity, which I highly recommend people read too, where he talks about, you know, how there are all these different material problems. And we came up with solutions thanks to science and better explanations and better research. And I'm personally all for that. But, you know, some people will not want to participate in that world anymore. And I think AI is such an accelerant that it makes that question even more pertinent for people.

42:02That's fascinating. I mean, just to keep going down that path before we go back to our little tour of frontier science, how would that manifest? I mean, so we would end up with groups of people that would deliberately opt to just not participate in progress. I guess progress has been sort of jagged throughout humanity in different regions, obviously. But as it spreads and as the world keeps going more global, those people make a political decision to organize around a principle of non-participation in AI. Yeah, I mean. Like is that city-state, that kind of stuff? Yeah, I mean, like a sort of example that I'd love to visit actually is Bhutan.

42:44Bhutan decided we will not measure our gross domestic product based on money, but based on happiness. And happiness mostly for people who want to keep it simple and have a simple life, not want to build startups and so on. I'm pretty sure those folks aren't quite as happy in Bhutan. But like overall, Bhutan is just very green and like it cares about the environment and cares about like a specific subset of religions. And like and people are more often content in keeping things the way they are rather than trying to like progress in various different ways. This is why this book and this conversation today, from my perspective, is so important.

43:24And I think the AI industry has done a terrible PR job in general. so if you and you know others can clearly articulate why is good that may hopefully unlock some of this debate yeah it's really interesting because clearly people use the technology it's like if no one used chat gvt or cloud code like there wouldn't be a problem people clearly like it it's just that the people get a lot of use out of it are not quite as vocal and you are there are negative things there's also some amount of moral panic about chatbot friends, similar fashion to how novels used to be a really bad thing. Like there's all kinds of stories of older people saying, oh, these novels are ruining the youth.

44:07They're now living in these dream worlds and are distracting themselves from the real world. And like, you know, like the Leiden des Jungwerters is a very famous book in Germany, actually led to some suicides, is really sad. And like now it's like the book every German kid has to read in high school. And it's just like a high form of literature in Germany. And then comic books were really bad and computer games were really bad. And like, you know, there are various sort of levels of that. And currently the chatbots are really bad, but there are also clearly a lot of people get a ton of value out of these chatbots.

44:37And now all of a sudden you make access to like medical advice cheaper, legal advice cheaper, and sometimes also emotional advice cheaper. But you don't hear many people like, or the many people that clearly exist, who are like hundreds of millions of users of these technologies talk about how much this helped them not commit suicide or something or not be very sad and dysfunctional and so on. So I do think you're right. Like in some ways, not just AI, but I feel like the future as a whole needs better marketing. All right. Going back to our tour, because I want to make sure we cover some of the fascinating parts of the book.

45:13So we talked about drug discovery. We talked about computational biology. Another fun example or domain that you mentioned is economics. with a fun stat where you said economists failed to predict 148 of the last 150 recessions. And so your team, while you were at Salesforce, built an AI economist that basically operated on a simulated society. And you came up with policy recommendations that were better than the state of the art, quote, end of quote. Walk us through that. Yeah, economics is a really interesting field that unfortunately doesn't have obvious benchmarks the way computer science and many other sciences have, where you just say, if you do better in this benchmark, you clearly have the better ideas, the better algorithms, and we should all learn and study those.

46:06when we submitted these papers and two-level reinforcement learning systems to nature and science, they just desk rejected them. In one case, some random like ethicist who had no idea about AI, it was just like desk rejected. I'm not even going to read the full paper because AI for economics with reinforcement learning is just a weird thing. And so it was just like gone. And so because of that, economics often becomes just a political field. And if you're in one economics department and has a political certain slant and direction they want to see the world move into, you just have to write papers that make sense for that political ideology.

46:46And so that unfortunately makes it very hard to do more objective research. And so we try to create the simulations, a very, very simple simulation where you have a bunch of agents, you know, like this is from 2018. The agents were much, much simpler back then. They just had a certain utility function. They had certain hours in the day that they would be willing to work. They were sampled from certain priors that you may make assumptions about. Not everyone wants to work 14-hour days, but some people basically make all these assumptions. And then you let these agents collect resources, build houses.

47:21They can block other agents from those resources to try to build monopolies and become even wealthier. And then you had a sort of meta agent that looked at all of these other agents and basically chose how to tax and subsidize different groups of agents. And in that fairly simple simulation, you could essentially give it an overall reward. Like in our case, we said, let's maybe start with equality times productivity. You want the economy to grow, but you also don't want one agent to have access to everything and everyone else is really poor. And so obviously you don't want just equality and you don't just want productivity.

47:59So you have a combination of these two multiplicatively. And now if you agree that that's a good reward, you could have politicians say, well, I'm going to do this and that to help, for instance, the middle class or like to do this and that. But if we had a much larger scale up simulation, you could then run their one proposal through billions and billions of years of simulations and of taxation and subsidization to say, well, will that proposal really result in that outcome that you say you have, the goal that you have? Or maybe, probably, if you simulate billions and billions of years of different tax years, maybe there are better ways.

48:40And what we found is that the agents will try to avoid taxes by dumping a bunch of stuff before or making like a bunch of gains just after the tax year and so on. And the funny thing is that paper, basically the baselines that the field uses, one very famous formula is called the Sayes formula in economics. And basically it's beautiful math. And it shows that provably it's the optimal taxation scheme, but it's the optimal taxation scheme in a one-step economy where you make one economic decision and then no other decision again. And so we showed that this very complex RL system basically recovers that thing and does come up with the same solution.

49:20But now you can actually deal with the fact that economics is a temporal sequence of many different decisions and you can learn and adapt and there are counter adaptations from the agents to certain taxes and subsidy schemes that are trying to play things and then you can still simulate it. And so my hope is eventually that that paper will have kind of a GPT-3 moment where someone actually scales it up, builds a really realistic simulation and then we could have AI give us feedback. Obviously, you don't want to let the I make those decisions without any human oversight, but at least have some economic policy suggestions on how to most objectively try to achieve the goals we want to set.

49:58And of course, humans then have to really formalize kind of what is the goal of our society. And in many ways, these are very deep questions that philosophy and political philosophy have asked many times. Socialism, capitalism, like maybe social market economies where some regulation in like healthcare, but maybe not in other areas and you want competition. You can actually define once like what your real goals are. So I think hopefully over the years, this kind of system will help us run economics much better and make it a much more objective science. Do you think that's realistic that we could model all of the economy, you know, with all its nuances?

50:40There is an emerging space around simulation of worlds and, you know, a couple of exciting companies in the space. But at the same time, the economy is a lot of rational decision, but a lot of irrational stuff. It's very human. There's fears, there's greed. Can all of this be modeled by AI? All models are wrong. Some are useful. I think we can make those models more and more useful and they'll be less and less wrong. I think we've seen surprising results where you can prompt an LM and say, you are now, you know, a 43 year old, like from this region, blah, blah, blah, blah, blah. Give them all kinds of sort of prompts on what they're supposed to act like.

51:25and then after having trained on tens of trillions of tokens on the internet you can say similar things to what people might say from that setting and so I do think these models will get better and better the fidelity of the simulations will get higher and once they cross a certain threshold then the recommendations from such a simulation with an AI could become more useful I don't think this is very feasible in the United States for a very very long time it's just so much identity politics and special interest groups and how, you know, super PACs and so on are like get funded. That is very, very unlikely to be used.

52:01My hunch is like Singapore or China will probably be more likely to try to use those ideas. Say, hey, we all agree or we at least make it very clear that this is our objective function. And then, you know, we're going to really try our best to set the various taxes and subsidies and so on in a way that really achieves that objective function. Okay, great. So we talked about drug discovery, computational biology. That was the economics aspect. You talk about astronomy. You talk about neuroscience. So again, I strongly encourage people to read the book and hear all the stories and all the nuances.

52:39Let's talk about the European machine itself. You alluded to four stages. And maybe as we get into that question, there is also the question of the quality of the data that is fed in all those machines. Because if you train AI on a lot of AI data, don't you inherit all the biases and the assumptions and all the stuff that is just wrong, that is spread out through all of human history? Yes, I think AI often is only as good as the people, the data, the systems, the infrastructure, the rewards that we give it. And we have to be very careful about how we design and filter out all of those things. I think we have more and more control over it, but it is still surprising how poorly engineered some of the environments are and some of the sandboxes are that Frontier Labs use for AI.

53:41So let's get into the machine itself. So you got four core pillars. Walk us through the first one. so uh yeah the four pillars i briefly alluded to them earlier um where like the first one is just large language models essentially to try to ingest the world's knowledge uh into uh the eureka machine and uh i think the interesting bit here actually is that in some ways uh there's this weird cycle that happened uh that don't talk about it in the book as much uh but it sort of lived through this now, which is the few large closed labs, Anthropic and OpenAI, took almost everything they could from the open internet, trained a model, but then the Chinese open source companies basically siphoned a lot of that knowledge out of those closed source models by distilling it, but then they open sourced the model back into the open domain, so now the knowledge is back in the open internet where it started.

54:46And so I think it's very clear that that first pillar of just like having access to all the world's information, being able to reason through all these different concepts and the crazy large commentatorial space of existing knowledge is the first pillar. So pillar two is a model of reality itself. So what does that mean? If you think about how limited human perception and the current set of human knowledge is and how we could actually expand that, you have to look at scientific measurements, right? We cannot observe gravitational waves. We cannot observe sort of gamma rays, but we can build tools and scientific machines that measure these things for us.

55:33And so that is a clear second pillar that is different to human knowledge that in some cases hasn't been fully sort of described in human language. And in some cases might be very complicated to describe in human language. Like we can already say, oh, like a neural network predicted this word because of these 5 million parameters. But it's like, okay, well, you just list them all out, but you don't gain an intuition because the system is so complex. Similar to how no one can really say, why did you move this muscle fiber in your pinky when you try to move the steering wheel? No one has access to that in their brain.

56:08And even if they did, it would just be like because of this very complex system. And so that is basically the ability of an AI to take in all of these measurements and try to start actually like digesting it and taking real knowledge, extracting it from scientific measurements. And PLO1 sounds like it already exists. Does PLO2 exist? How do you teach a machine the rules of the universe? So one, you'd have to really collaborate with a lot of different sciences to put together this kind of foundational model of physics, chemistry, biology, and larger and larger systems, and then have many universities and labs work together to bring all of that into one model.

56:56So I think, you know, we've had sort of the projection of the humanities knowledge onto the internet, but there's just lots of things that just don't make sense to put up on the internet. And so those things are still hidden. No one, people have many, many companies are now working on quote unquote foundational models. Some of them now rebranded them as world models when there's a similar technology below where they basically try to ingest as much information about one domain. and then they build like a first example of a virtual cell that is particularly good at estimating like particular gene variants or something, but not lots of other aspects of a virtual cell.

57:32A virtual cell is a good example of like a goalpost where many different teams would have to come together and bring all of that data into one unified model. No one in its full glory, that doesn't exist yet. Okay. And then pillar three, again we're describing the the the four pillars of the york machine what you call the york machine which is this super powered ai scientific discovery machine so pillar three is simulation so that that goes a little bit to what we were discussing about economics so would you create different simulations for different domains or one simulation for everything in a perfect world we'd create one crazy simulation for everything but it they're obviously sort of different levels of abstraction and sometimes for most aspects you actually get away with not having to simulate all the quantum details of a very complex like subatomic particle you can just say all right these are the molecules and then you you know how in chemistry those molecules will work together based on the valence shells blah blah and then in biology you sometimes just can abstract from like oh i don't even care about that molecule i'll just say this is overall this protein and that protein and has like connects to a cell at that level.

58:46So as you try to build it all together, but then you have to have sort of computational efficiencies and abstractions that humanity has been good at building and computer science is particularly good as a field in building. Like no one has to program in zeros and ones anymore. They can now program in English and a lot of the abstractions can be ignored. I think similarly in these physical simulations, we can ignore more and more levels down. But sometimes like there is sort of quantum biology and there are maybe some effects that we didn't realize and we're oversimplified. And those might come out from a model where you're like from one large simulation in which the AI can then try to experiment.

59:23And that level three or pillar three exists in bits and pieces? In many small bits and pieces, right? The simplest example is like a simulation of Go or chess. And that's like, okay, we have it, it's easy. An interesting new one that many people are working towards now is a virtual cell. If we had that, I mean, a virtual cell is so complex, like a real human cell is so complex. We're very far away from that. But I can see how with enough people coming together with enough funding, we can eventually get to a fairly useful model of a virtual cell. Okay, great. And then pillar four is the real world.

59:59That's right. At some point, like especially in biology, but in all other fields, you have to engineer a system. You have to really put it together to see if you missed anything in your simulation, any confounding variables and so on. you have to really run experiments in the real world. And obviously in the smaller case of physics, chemistry, and biology, you can do that in a lab. At some point you have to, you know, build real machines and really get out there and build satellites and whatnot and take measurements of, you know, the universe and all kinds of scales. And so, you know, there I think we, like, it makes sense for us to put more and more resources behind that as AI has gotten really, really good in the first three pillars.

1:00:38So there's some sequence to it. And is the future a concept of self-driving robotic labs? And if so, how far away are we? You know, I love that there are like first efforts in this, like periodic labs is a great example of that. I love that we're starting to think about this. Personally, from an investing perspective, I feel like it's a little bit early, but in like two to three years, I think it'll be right on time. We'll have figured out a lot of the software, will have gotten, will be really good at, you know, the LMs, the scientific sort of data and like connecting that also potentially to LMs, like building even more high fidelity simulations.

1:01:19And then we can ask the AI to ask, like to come up with really good, expensive experiments that can take sometimes hours or days or weeks to really run through. We'll have better organoids or like tiny cell systems where you can, you know, base the human derived stem cells, a parallel bio disease, for instance, for human lymph nodes, like immune cells. And then you can experiment with those cells more quickly. And that is done with robotics already. So few real examples of that exist. I think there's a chemputer too in chemistry that can put together a small set of molecules. their first examples of this with parallel bio with like organoids and doing clinical trials of that by the way that alone that company alone has already gotten FDA approval to skip certain animal trials so you save many many millions over the next few years and lives of animals that are just bred to then be tested upon and then dissected and evaluated and this like if you love animals you can also love ai because ai is now already not just will eventually but through this one company parallel bio it's already saving animal lives uh that are just again bred for being uh like tested upon and so i think there's like tons of really uh amazing um work that is very targeted to build these out in more and more generality is kind of what is required to then allow the ai and the agent swarms to sit on all of these four pillars more efficiently yeah and To finish the tour, so there is like this agent swarm.

1:02:56So what do the agents do? Do they decide which experiment to run? Or is a human still deciding what the machine runs? And do the agents measure what's coming out? Or is it a human measuring it? How does that work? The agents will ideally work on as much of the scientific process as possible, similar to how scientific communities do it. And in many cases, the evolution of science and culture and even biology has aspects of open-endedness, which is very inspiring for us at Recursive also, and are actually basically exploring interestingly different ideas, highly in parallel, that then can then be recombined.

1:03:43combined. And so these open-ended processes have led in biology to everything from, you know, our fingers, eyes, and brains. In technology, there are lots of examples where, and Jeff Kloon, one of our co-founders at Recursive, talks about this a lot, how you can't get a microwave if you just say, make this pot faster in heating up my food, right? And you just like, you add all kinds of pressure and so on, but you had to work on radar technology and realize like some like chocolate bar in your pocket was melting as you work in radar to then eventually get to a microwave to then like like warm up your food faster and so there are like these different paths and recombinations of different research ideas that can be coming together and we can model that better and better with with agent swarms it sounds like an incredibly compute hungry and data hungry machine given the complexity of what it is that we're trying to model, especially as we think about cross-domain pollination?

1:04:44Do we have enough compute? Do we have enough data? I mean, Ilya said we've reached big data. Does the machine need to create its own data? What are the constraints? Indeed, compute is the biggest constraint. I think in the future, more and more humanity, and already we see this inside different companies, will have to decide Like what problem is worth solving? How much compute do we give to solving that problem? And then there will be new kinds of scaling laws where we give enough compute to really solve different kinds of problems. And yes, I think there's like the majority of the public Internet has been digested by a lot of these labs.

1:05:26But there's always new data. There's always new things that happen in the news. That's why, you know, U.com, we work with a lot of like Neo Labs and other labs also to just give them constantly new search results when they ask about something that just happened last week and wasn't yet part of any training data set. All right. So thanks for that. So a lot of those ideas are embedded in your new startup called Recursive. Tell us about the company. Yeah, so Recursive started with the goal of building Recursive self-improving superintelligence to automate knowledge discovery and scientific discovery.

1:06:03And it came, actually, the eight co-founders came together and we all in one form or another came to the same realization, but actually from very different directions. Tim Rock-Teschel and Jeff Klune, for instance, came very much from this open-endedness research direction of evolutionary algorithms and so on. And I came very much from this idea of, well, we automated feature engineering to have word vectors. We have neural nets. Then we automated architecture engineering by just having one unified architecture. What's the next level of automation? It's like the actual ideation and implementation validation of general ideas in all of AI research.

1:06:39And that's like clearly and obviously the next level to unlock a new set of capabilities. And when you think about the automation of science and then you apply the automation of AI research to, you know, AI like itself, before you know it, you're in this recursive self-improvement loop. And we believe that that will be a great unlock to then apply that kind of intelligence to all kinds of other scientific discoveries. And you guys raised a massive round of 650 million. And interestingly, to the compute discussion that we were just having, I read that you committed 410 million, basically most of what you've raised to a single compute deal with Amazon.

1:07:18So that goes to show the fundamental importance of compute. Yeah, we raised in the end like 670-ish. And yeah, that will probably be one of the smallest compute deals that will happen in our future. And so what can we expect from the company? What is it that you guys are going to release first? By when? There will be a couple of interesting things coming up. I can guarantee you they will happen this year. We are, and I struggle with this sometimes, the Neolab category. I don't love it because I think a lot of them will not succeed. We are a real company, not an academic lab. We are building real products.

1:07:58We're talking to real customers. And we're very excited of taking this technology and making it useful for real companies. I can't share the details yet of what we're going to release, but I think it'll be exciting. And we already know from some first conversations that it is exciting. But is that going to be horizontal or focused on a specific vertical along the lines of what we discussed? I would like there will be different, there is a sequence to it and some things will be general, but then obviously at some point it'll be more and more specific. I think we did publish a blog post that gives you a little bit of a glimpse of things we're thinking about that are essentially milestones towards full recursive self-improvement.

1:08:34that showed that, for instance, when a lot of people use AI or do some auto-research on small models, our system, the sort of first instantiation of this Eureka machine and a very narrow domain can already outperform months and sometimes years of human endeavor on particular problems. We also showed that they can build new CUDA kernels, which is very useful for faster inference, which is very useful for all large hyperscalers and people who provide tokens and run models. And we're very excited to keep pushing those. And we've heard very positive feedback from folks who are using these kernels now and have, like at NVIDIA, folks had created these benchmarks, the sole exec bench is a particular example there.

1:09:21So yeah, those are all just simple examples of artifacts that this Eureka machine can produce when it comes to AI research on the path to full RSI. And as an aside, I cannot resist asking the question why are most Neolabs not real companies? I mean, they're just like ideas of like, we want to explore, you know, this particular idea. And that particular idea is like, you know, it's one of the many useful artifacts our Eureka machine could also produce, but it's not really a product. Like, you know, if you just want to try to think about how humans interact with AI in the future, that's not quite like anything very concrete.

1:10:02And so you have to be very careful about, you know, what are founding teams and so on that have not just done amazing research, but also shipped real products. All right. To end, I want to talk about intelligence and super intelligence and where all of this is leading. So the book ends by asking a huge question. How far can intelligence go? And you propose your own definition. So maybe talk to this. Yeah, that one will take us more than the time we have left. I feel like it's almost like a new book. I had to wrap it up at that point, the book. And so one, I'm surprised no one has really defined intelligence in all of its complexity really well.

1:10:43Neither in terms of the very foundational building blocks, which I currently think are prediction, action and goals and a combination of those three. Those are sort of the three principal components. Just like sort of energy has one unit. We don't yet know what this is a unit of intelligence, something I'm thinking about a lot right now. We don't yet then have a proper definition, sort of physics inspired, you know, in physics, we have kinetic and potential energy. But then it also makes sense to study chemical energy and mechanical energy and electrical energy and different forms. And some are like still pure science fields and others are very much engineering fields.

1:11:22And so I think a similar thing has happened in AI where we have visual intelligence, language intelligence, physical intelligence and robotics. And I define these 10 different spaces of intelligence and each space basically has many different dimensions. And I'll just give you this one example on visual intelligence. We have AI can only, sorry, humans can only see in a specific part of the electromagnetic frequency spectrum. But you can go much beyond humans when you think about what are the bounds of visual intelligence? How far could an AI or any kind of intelligent life form or entity in the universe push visual intelligence?

1:12:03And then you get into very interesting sort of often physics inspired kind of like thoughts and loops. For example, you can see everything from gamma rays to gravitational waves. So very different, like the whole spectrum of electromagnetic frequencies. You can try to have not just two eyes, but you can have millions and billions of different sensors all throughout. But then how far could they go? Well, at some point you have communication bounds of the speed of light. And you have each sensor has sort of a speed of light cone around what it can see. And you quickly get into these thoughts around bounds.

1:12:44And what you then realize is that, boy, are we far away from the true upper bounds of any of the spaces of intelligence. And there's still so much further that AI can go in research. And so when people think, oh, you know, this set of algorithms or the field of AI is sort of like, it's a bubble is going to burst. I mean, maybe like energy, right? The cost, the unit cost of intelligence may fluctuate depending on a bunch of factors, but we can still go so much further as a field and as a civilization and pushing that field forward. All right, Richard, this has been another fascinating conversation and I could keep you for another couple of hours.

From the publisher

What happens when AI begins improving itself, and then turns that intelligence toward science? Richard Socher, pioneering AI researcher and CEO and co-founder of Recursive, joins Matt Turck to explore the vision behind his new book, The Eureka Machine. They discuss why scientific progress may be slowing, how large language models can learn the hidden languages of proteins and biology, and why simulations, verifiers and autonomous experiments could unlock superhuman AI capabilities. The conversation covers recursive self-improvement, AI drug discovery and cancer research, hallucination as creativity, virtual cells, self-driving laboratories, agent swarms, the AI Economist, Recursive’s plans, and the compute and data needed to build an AI scientist that never stops learning—and may eventually discover what humans cannot.
