`00:00` DeepMind’s Origins, Gaming Roots, and the Common Thread
Konstantine Buhler introduces Demis Hassabis as "one of the OGs" and a true visionary across AI, neuroscience, and entrepreneurship, welcoming him to the "chocolate factory" before diving into his background. Hassabis explains that while his career trajectory—from chess prodigy to game developer, neuroscientist, and founder—might seem disparate, there is a deliberate thread connecting every stage. By his mid-teens (around 15 or 16), he realized AI was the most important and fascinating field he could pursue, and he systematically chose subsequent endeavors to build the skills needed to found a company like DeepMind.
His detour into gaming in the 1990s was strategic: at the time, video games were the bleeding edge of technology, driving advances not just in software and AI, but in graphics and hardware. Hassabis notes that he was using the very first GPUs in the late 1990s long before they became the backbone of modern AI training. Every game he developed, both at Bullfrog Productions and later at his own company, Elixir Studios, featured AI as a central gameplay mechanic.
At age 17, Hassabis co-designed *Theme Park*, a simulation game where thousands of virtual guests navigated an amusement park, made purchasing decisions, and rode attractions, all governed by an underlying economic AI model. The game sold over 10 million copies. Observing players' genuine delight when interacting with these AI systems solidified his commitment to dedicating his career to AI. Following his time in games, he pivoted to computational neuroscience to study how the human brain functions and to harvest algorithmic principles for synthetic intelligence.
* **Key Career Milestones:** Chess prodigy $\rightarrow$ Game developer (Bullfrog, Elixir) $\rightarrow$ Computational Neuroscientist $\rightarrow$ Co-founder & CEO of DeepMind.
* ***Theme Park* Impact:** Co-designed at age 17; sold 10+ million copies; proved that complex, underlying AI simulation could drive massive consumer engagement.
* **Hardware Evolution:** Utilized early GPUs in the late 1990s for game engines decades before accelerated computing became standard for modern AI models.

`02:40` Elixir Studios and the Lesson of Being Too Far Ahead
Buhler pivots to Hassabis’s early entrepreneurial experience as a two-time founder, asking about his first startup, Elixir Studios, which he launched straight out of university after working at Bullfrog Productions—European gaming's premiere studio at the time. Hassabis candidly reflects on how Elixir effectively served as a vehicle to "fund AI... through the backdoor" via game development, combining blue-sky research with cutting-edge creativity.
However, Elixir taught him a vital operational lesson: **"you want to be five years ahead of your time, not 50 years ahead."** At Elixir, they attempted an overly ambitious title called *Republic: The Revolution*. The game aimed to simulate an entire living, breathing nation of one million dynamic individual inhabitants—including politics, cities, and economic systems—where players could overthrow a dictator through various strategic means.
Attempting to run full graphics and AI simulations for one million citizens on late-1990s Pentium home PCs created immense technical strain. Hassabis acknowledges that while being ahead of the curve is necessary—because entering a market when it is obvious to everyone means you are too late—being half a century ahead makes execution nearly impossible with existing hardware.
> "You want to be five years ahead of your time, not 50 years ahead... when it's obvious to everyone, it's too late. But if you're 50 years ahead, then there's probably no way you can get it to be successful."

`04:40` Founding DeepMind in 2009 and Pitching AGI Sci-Fi
Moving to 2009–2010, Buhler asks how Hassabis convinced elite academic and technical talent to join DeepMind when working toward Artificial General Intelligence (AGI) was widely viewed as pure science fiction. Hassabis jokes that while they thought they were five years ahead of their time, they were probably closer to ten.
He outlines the core insights that convinced him and his co-founders that AGI was achievable:
1. **Deep Learning Breakthroughs:** Geoff Hinton and colleagues had recently introduced modern deep learning in academia, though few outside a tiny circle recognized its transformative potential.
2. **Merging Reinforcement Learning & Deep Learning:** Reinforcement learning (RL) and deep learning existed in heavily isolated academic silos, mostly applied to toy problems. Hassabis saw that combining them could unlock unprecedented capabilities.
3. **Accelerated Computing:** The rise of performant hardware (GPUs at the time, later transitioning to Google's TPUs) provided a scalable foundation.
4. **Neuroscience Principles:** Insights from computational neuroscience suggested that RL mechanisms in the human brain could scale to general intelligence.
Despite these promising signals, the broader academic and industrial communities met their vision with extreme skepticism. Traditional AI hubs like MIT and Cambridge were still deeply committed to classic expert systems, logic languages, and rule-based architectures built in the 1980s and 1990s. When DeepMind's team brought up AGI or "strong AI," academic colleagues literally rolled their eyes, having concluded from 1990s failures that general AI was impossible. Ironically, this dismissiveness gave Hassabis confidence: if DeepMind failed, they would at least "fail in an original way" rather than repeating old paradigms.
> "Our original mission statement at DeepMind was step one, solve intelligence, i.e. build AGI. Step two, use it to solve everything else."
* **20-Year Horizon:** In 2010, DeepMind mapped out AGI as a 20-year mission (targeting ~2030), a timeline Hassabis notes the field remains precisely on track to meet.
* **AI as an Empirical Science Tool:** Beyond building products, Hassabis viewed AI as a essential tool to study consciousness, dreaming, and creativity by providing a controlled computational model to compare against biological minds.

`09:05` AI for Science, AlphaFold, and Isomorphic Labs
Buhler highlights Hassabis's long-standing insistence that the ultimate mission of AI is advancing fundamental science. Hassabis explains that this meta-goal—building the ultimate tool to unlock scientific breakthroughs—led to the formation of DeepMind’s dedicated "AI for Science" division, led by Pushmeet Kohli.
The division was formally established roughly a decade ago, immediately following AlphaGo’s historic 2016 victory against Lee Sedol in Seoul. Hassabis waited until algorithms had matured beyond games before deploying them to grand scientific challenges.
The standout result of this focus was **AlphaFold**, which solved the 50-year-old grand challenge of predicting 3D protein structures from amino acid sequences. However, predicting structure is only the first phase of drug discovery. To complete the pipeline, Hassabis launched **Isomorphic Labs**, a spin-out company focused on biochemistry and chemistry AI.
Isomorphic Labs builds adjacent models to computationally design novel chemical compounds that precisely bind to targeted protein sites while avoiding off-target interactions that cause side effects. The goal is to perform 99% of drug design in silico, reserving wet labs purely for final validation.
* **Drug Discovery Timelines:** Modern drug discovery takes an average of 10 years; Hassabis envisions AI collapsing this timeline down to months, weeks, or eventually days.
* **Impact on Healthcare:** Accelerating discovery could bring every disease within therapeutic reach and enable personalized variations of base medicines.
* **Broader Scientific Frontiers:** Beyond biology and medicine, AI for science is being aggressively applied to material science, clean energy, and environmental sustainability.

`12:40` New Scientific Disciplines and AI-Driven Simulations
Buhler asks whether AI will give rise to entirely new scientific disciplines, comparing the potential shift to how the Industrial Revolution catalyzed thermodynamics. Hassabis predicts two major transformations:
1. **Mechanistic Interpretability & AI Analysis:** Understanding, evaluating, and analyzing complex neural networks will become an engineering science of its own. As AI systems approach human-level complexity, mechanistic interpretability will be required to unpack their inner workings.
2. **AI-Driven High-Fidelity Simulations:** Hassabis envisions AI powering ultra-precise simulation engines capable of formalizing "emergent" human systems—such as economics, macro-policy, and social sciences—into rigorous quantitative sciences.
Currently, fields like economics cannot easily run repeated, controlled experiments; testing an interest rate adjustment requires executing it in the real world with unrepeatable variables. High-fidelity AI simulations will allow researchers to sample thousands of probabilistic scenarios, enabling data-driven decision-making in previously uncertain human domains.
`15:00` Learning Simulators and Information as the Fundamental Substance
Demis Hassabis explains DeepMind's work on "learning simulators" for domains where underlying mathematical equations are either unknown or too complex to write down directly. For example, their weather simulation model, WeatherNext, is significantly faster and more accurate than traditional meteorological systems. Similarly, DeepMind is working on a "virtual cell" to simulate complex biological systems. Hassabis argues that machine learning serves as the ideal description language for biology—much like mathematics does for physics—because biological systems are filled with vast amounts of noisy data, weak correlations, and dynamic, emergent behavior that no human mind or traditional mathematical framework can fully process or express. He suggests that once an implicit neural simulator learns a complex system, scientists might even be able to extract explicit, fundamental equations from it through repeated sampling, potentially opening up entirely new branches of science.
The discussion pivots to a theoretical perspective on the nature of reality: the idea that information, rather than energy or matter, is the most fundamental building block of the universe. Hassabis notes that while Einstein proved the equivalence of matter and energy ($E=mc^2$), structure and biological processes that resist entropy can be understood as information processing systems. He views information, matter, and energy as interconvertible, but considers information primary. Under this paradigm, AI becomes even more profound, as its core function is the organization and processing of information. Turning to classical computation, Hassabis references Alan Turing as one of his all-time scientific heroes and calls DeepMind "Turing's champion." He highlights how results like AlphaGo and AlphaFold demonstrate that classical Turing machines—operating via modern neural networks—can successfully approximate complex quantum systems like protein folding without needing to simulate every quantum detail directly.
- **WeatherNext:** DeepMind's weather model, which operates faster and with greater accuracy than traditional meteorological systems.
- **The Virtual Cell Project:** An effort to construct a dynamical simulator for biological systems using machine learning as a native descriptive language.
- **Turing Machines & Quantum Systems:** AlphaFold demonstrates that classical architectures can approximate complex biological systems (which are inherently quantum at small scales) with optimal practical precision.
`20:00` AI Tools vs. Autonomous Agents, Consciousness, and Philosophy
Addressing whether highly capable AI will eventually transcend being a mere "tool" (like a telescope or microscope), Hassabis emphasizes that the safest and most effective approach is to focus on building an extremely capable, precise, and intelligent tool first before crossing further Rubicons. While AI is entering the "agent era" with increasing autonomy, questions around true agency and consciousness represent a distinct secondary phase. He suggests using AI as a tool to help humanity better understand the human brain and establish more precise definitions of consciousness. Reflecting on past discussions with the late philosopher Daniel Dennett, Hassabis breaks consciousness down into two main lenses: behavioral and experiential. While AI systems near AGI may mimic conscious behavior, proving experiential consciousness in an artificial system is difficult because humans share a biological substrate—a substrate equivalence that artificial systems inherently lack.
When asked about his philosophical inspirations, Hassabis highlights Immanuel Kant and Baruch Spinoza. From Kant, he takes the view that "the mind creates reality," underscoring the importance of studying neuroscience to understand how the brain interprets the universe. From Spinoza, he draws a spiritual perspective on science: the idea that using AI and scientific tools to unveil the universe's mechanics is akin to reading the "language of the universe."
- **Key Components of Consciousness:** Hassabis highlights self-awareness, a sense of self versus other, and temporal continuity as necessary (though potentially insufficient) criteria.
- **Daniel Dennett:** Hassabis references past conversations with the philosopher regarding behavioral vs. substrate-based proofs of consciousness.
- **Philosophical Foundations:**
- **Immanuel Kant:** Mental models construct our perception of reality.
- **Baruch Spinoza:** Scientific inquiry and uncovering nature's laws act as a spiritual endeavor.
`25:00` Rapid-Fire Questions and AGI Timeline
To close the session, Sequoia Capital partner Konstantine Buhler leads a rapid-fire Q&A segment. Reaffirming his long-standing prediction, Hassabis states he remains confident that AGI will be achieved by **2030**. When asked to recommend a essential read for the post-AGI era, he selects David Deutsch's *The Fabric of Reality*, expressing hope that AGI will help answer the fundamental questions posed in the book. Reflecting on DeepMind's history, he names the breakthrough with AlphaFold as his proudest moment to date. Finally, when asked which historical scientist he would draft as a teammate for a high-stakes, turn-based strategy game like *Civilization* or *Polytopia*, Hassabis chooses mathematician and game theory pioneer John von Neumann.
- **Target AGI Timeline:** 2030 (a timeline Hassabis notes he has consistently held).
- **Recommended Reading:** *The Fabric of Reality* by David Deutsch.
- **Proudest Milestone:** The development and success of AlphaFold.
- **Dream Strategy Teammate:** John von Neumann ("You want a game theorist... and I think he's the best").

DeepMind co-founder and CEO Demis Hassabis argues that artificial general intelligence is progressing on schedule toward a 2030 arrival, serving primarily as an empirical tool to unlock fundamental scientific breakthroughs and simulate complex emergent systems.
Strategic Origins and the Path to AGI (0:00)
Hassabis traced his career trajectory through chess and video game development at Bullfrog and Elixir Studios as deliberate preparation for AI research, noting his use of early GPUs in the late 1990s and his co-design of Theme Park at age 17. His first startup, Elixir Studios, taught him the operational pitfall of being too far ahead of contemporary technology when Republic: The Revolution attempted to simulate one million dynamic citizens on late-1990s Pentium PCs. Hassabis noted that entering a space when it is obvious is too late, but being decades ahead makes execution nearly impossible.
DeepMind was founded in 2009–2010 around the convergence of deep learning, reinforcement learning, neuroscience principles, and accelerated compute. Despite skepticism from an academic establishment focused on 1990s-era rule-based systems, DeepMind mapped out a 20-year roadmap to achieve AGI by roughly 2030. Hassabis maintains that the field remains directly on track to meet that timeline.
Transforming Scientific Discovery and Biology (9:05)
DeepMind established its dedicated AI for Science division following AlphaGo's 2016 victory, leading to AlphaFold's solution to the 50-year-old challenge of predicting 3D protein structures. To commercialize and extend this capability, Hassabis founded Isomorphic Labs, which applies biochemistry AI models to design chemical compounds that bind selectively to target protein sites while minimizing off-target side effects. Hassabis projects that moving 99% of drug design in silico could compress typical 10-year pharmaceutical timelines down to months, weeks, or days.
DeepMind is expanding this paradigm through learning simulators, which Hassabis considers the natural descriptive language for biology—a domain dominated by noisy data and dynamic interactions that resist traditional mathematical equations. Current initiatives include WeatherNext, which outpaces standard meteorological models in speed and accuracy, and a virtual cell project designed to dynamically simulate living systems.
Simulating Emergent Systems and Information Theory (12:40)
Beyond biology, Hassabis anticipates AI will establish mechanistic interpretability as a formal engineering discipline to unpack neural networks, while high-fidelity AI simulations will formalize human domains like macroeconomics into quantitative sciences. Because researchers cannot run repeated, controlled macro-policy experiments in the real world, AI simulators could allow policymakers to evaluate thousands of probabilistic counterfactuals prior to implementation.
From a theoretical standpoint, Hassabis regards information as more fundamental than matter or energy, describing biological structures that resist entropy as information processing systems. He highlights that classical Turing machines—operating through modern neural networks like AlphaFold—can successfully approximate complex quantum biological systems with practical precision without needing to simulate every quantum variable directly.
Tool-First Development and Questions of Consciousness (20:00)
As AI transitions into an era of autonomous agents, Hassabis advocates prioritizing extremely capable, precise tools before addressing true agency. Drawing on Immanuel Kant's view that the mind constructs perception and Baruch Spinoza's perspective of scientific inquiry as uncovering the language of the universe, Hassabis views AI as a computational lens to study the human brain.
On the subject of consciousness, Hassabis cites discussions with the late philosopher Daniel Dennett to separate behavioral imitation from experiential consciousness. While AI systems near AGI may mimic conscious behavior—such as self-awareness and temporal continuity—Hassabis cautions that verifying true experiential consciousness remains difficult because synthetic systems lack biological substrate equivalence with humans.
Hassabis positions the final stretch to 2030 AGI as an engineering and scientific effort focused on powerful discovery tools rather than conscious autonomous entities. Unresolved questions remain regarding whether learning simulators can eventually yield explicit fundamental physical equations, and how researchers will evaluate claims of artificial consciousness in the absence of biological benchmarks.

Original transcript
[0:00] Dennis, thank you so much. Exciting to be here. Thanks everyone for coming. It's great to be here. We're so honored to have you at our chocolate factory. Yes, I just heard about that. Looking forward to the chocolate afterwards. Excellent. Well, Dennis, we're going to jump right in. We have one of the OGs in every way. Original thinkers, founders, visionaries in all things AI. A true believer, true scientist in Dennis. We're going to spend the beginning of the conversation about the early days, then early days of DeepMind, and then we'll get into the science and open up the room for some questions. So let's jump right in. So Demis, you were a chess prodigy. You also were a founder of a gaming company. You're a neuroscientist, and you're the founder of DeepMind, now leader of a really big consequential company. Those seem like pretty unrelated pieces, but you've said that there's a common thread. Can you walk us through that? There is a common thread and maybe I made it into a common thread So it could be a post hoc you know sort of shaping But I wanted to do AI for a long time So I kind of decided it was the most important thing I could possibly and most interesting thing I could do in my teenage years And then I picked things to study or do that I felt eventually would help me build a company like DeepMind So I had that as a plan from about 15, 16 years old. I had a detour into games because actually that was in the 90s. This is that's where all the most cutting edge technology was being done. Obviously, not just in AI, but in graphics, especially, including hardware. Of course, the GPUs we all use today, they were designed for graphics engines. And we used the, I mean, I was using the very first GPUs back in the day in the late 90s. So there was a lot of really cutting edge technology. And then all the games I made, including all the games I did for Bullfrog, but also my own company, Elixir Studios, all involved AI as the main gameplay component. so probably the most you know well-known game I made was theme park when I was about 17 and that was a simulation of an amusement park and thousands of little people came into your theme park and played on your rides and decided what to buy from the shop so there was a whole kind of economics AI model underneath and it was one of the first games of its type along with SimCity and when I saw it sold you know 10 million plus copies and when I saw how delighted people were to interact with the AI you know that was one of the things that made me think about spending my whole career on it And then of course neuroscience is to get inspiration from how the brain works and different algorithmic ideas from that And then just bringing all those different things together for the start of DeepMind when the timing we felt was right. And then, of course, we use games as the early proving ground for our AI ideas. So we've got a room full of founders here, and you can relate because you're a founder not just once, but twice. Take us back to the first time, Elixir Studios. What was that like? It's not the startup that you're most known for, but it was one that you had incredible success with. How did you lead that and what did it teach you about building? Well, look, I started Elixir Studios straight out of college, and I was lucky enough to work at Bullfrog Productions, which, for those of you who know games, it was a kind of legendary game studio in the early days of the game industry, probably the best one in Europe. And I wanted to do something that combined, pushed AI. So effectively, I was funding AI back in those days through the backdoor, through games development, and then pushed the forefront of that and combine it with cutting edge creativity And I think that still relevant today with the way we do our blue sky research but maybe the biggest lesson i learned was you want to be five years ahead of your time not 50 years ahead so we tried to do a game called republic at elixir studios which simulated a whole country and then the idea of the game is you could sort of overthrow i think there was a dictator in charge of the country in any number of different ways and we basically simulated living, breathing cities. And this is, bearing in mind, this is like the late 90s on a Pentium. So we had to get all the graphics and all the AI for a million people working on, you know, a home PC at the time. So it was a little bit ambitious. And maybe it was too ambitious. And it caused some issues. And I took that lesson with me of like, you want to be ahead of your time, you don't want to be obviously, when it's obvious to everyone, it's too late. But But if you're 50 years ahead, then there's probably no way you can get it to be successful. All right. So speaking of not being too far ahead of your time, it was 2009 and you decided there would be AGI. Yes. Maybe it was only 10 years ahead of our time that time, better than 50 years. So tell us about, again, room full of founders here. Tell us about 09. How did you convince the first few brilliant talents?
[5:00] You pulled in really high caliber employees, early team members. How do you convince them to believe in what seemed like total sci-fi at the time? Well, there were some interesting threads that I think we picked up on. I think we thought we were five years ahead, but maybe we were more like 10. But it was, you know, deep learning had just been invented by Jeff Hinton and colleagues sort of in academia, but almost no one had really realized it was a big deal. we knew a lot about reinforcement learning and we felt there was huge progress to be made by combining those two techniques which almost had never been mixed together really certainly not any kind of anything other than toy problems in the academic subjects they were quite two quite siloed parts of AI then we could see the compute the GPUs at the time were going to be really useful of course we use TPUs now but the accelerated computing industry was was was going to be very helpful. And then we also felt at the end of my PhD in postdoc and some of the other people I got together were computational neuroscientists, that we had enough ideas and principles from the brain that could be useful including the idea that reinforcement learning could eventually scale to AGI So we felt we had these ingredients and we almost felt like we were keepers of a secret because no one either in academia or industry really believed that any big progress was possible. In fact, a lot of the people in academia used to literally roll their eyes up at us when we were sort of suggested we would work on AGI or strong AI, it was sometimes called at the time, because it was like, well, we know this doesn't work. So everyone tried it in the 90s and I did my postdoc at MIT which was the which is the sort of center point for expert systems and first of all the logic language systems I mean it seems amazing to think that now but I was already feeling like that was a chaotic then but they they you know that's still how it was done both in Cambridge in the UK and also in MIT these big centers of traditional AI and it felt like but actually that convinced me even more that we were onto something because at least if we were going to fail, we would fail in a different way than people had failed, you know, to get to AGI in the nineties. So that felt like it was worth doing, uh, no matter what, even if obviously it was research, we didn't know for sure it would be successful, but at least we would, we would fail in an original way if it didn work Was there any common sticking point in that early belief Was there something that you had to prove either to yourself or to your early followers to get them on board Well it was I mean we had put it this way I would have been spent my life on AI no matter what happened. So as it's turned out, it's gone, you know, it's sort of gone on the absolutely amazing side of the optimistic side of what we thought still actually within what we were predicting in 2010. We thought it would be a 20 year mission. And I think we're basically exactly on track as a field for that. And obviously we played our part in that. But even if it hadn't transpired that way, and it was still now a niche subject, that's what I would still be doing. Because I felt it was the most important technology ever, if it was obvious to me. Our original mission statement at DeepMind was step one, solve intelligence, i.e. build AGI. Step two, use it to solve everything else. So I always thought it was the most important technology that could ever be invented, but also the most interesting one. So as a tool for science, as an interesting artifact in itself, and actually as one of the best ways to understand our own minds, you know, like the nature of consciousness, dreaming, creativity, all of these questions I had as a neuroscientist, I felt one of the things that was missing was an analysis tool like AI but also a comparison that you could do sort of a controlled experiment study and compare two different systems against each other Let's talk about AI for science. You've been early to that. You've been a believer and you've been really a purist about this. This is the driving mission. What about the way you set up DeepMind and set the culture has positioned it to be on the constant forefront of AI for science? Well, that was the ultimate goal, at least for me, my personal passion. There's my own drive to build AI, which was to advance science and medicine and our understanding of the world. It's my expression of that mission was to sort of do it in a meta way, right? Build the ultimate tool and then come back when that was ready and use it to make breakthroughs in science. Things like AlphaFold that we've done and I think many more things. So we've always had that at the heart of what we've been trying to do at DeepMind. Actually, we've had an AI for science group division led by Pushmeet Kohli that has existed for nearly a decade now. Actually, pretty much the day after we got back from Seoul and the AlphaGo match, which is sort of 10 years to the month now, is when we started, formally started the AI for science efforts because I was waiting for the algorithms to be powerful.
[10:00] and the ideas to be general enough. And for me, you know, cracking go was that point that time that we thought, OK, now we're ready to really apply these ideas to important real world problems, starting with these big scientific challenges. So we've always had that in mind as the most beneficial use of AI, like what could be better than using it to, you know, cure diseases and give us healthier lifespans and to help with medicine, followed obviously by other really important areas like material science and the environment and energy and these kinds of topics, which I think AI is also going to have a huge part to play in the next few years. And how does AI break through in biology? You're deeply involved with isomorphic. This is an area of deep passion. You have been a purist on the potential of AI to cure diseases from the very beginning. When do we have the type of moment that we've had in language and coding, but in biology? Yeah, well, I mean, I'd argue we've already had one of those moments with alpha folds. So you know it a 50 year grand challenge protein folding and the 3D structure proteins is incredibly important thing to know about if you want to design medicines or if you want to understand biology Of course it only one part of the drug discovery process It an important part but it only one part So Isomorphic Labs which is our you know latest spin out having a lot of fun running that as well is to build adjacent technologies in more biochemistry and chemistry space that can actually design the compounds automatically to kind of fit and bind to the right part of the protein. So we now know the protein, the shape of the protein, we know that what's on the surface of the protein and what we have to target. But now we've got to build the right compound that, of course, binds strongly to where you want it to bind on the target of interest, but doesn't bind to anything else, ideally, because that would be a toxic side effect. So the dream is to do almost all the exploration, which is 99% of the work and the time in silico, and then save the the wet lab step just for the validation step. Right. So that would be, you know, I think if we can do that and I think we can get there in the next few years, I think we could reduce drug discovery times instead of that for taking like, you know, an average of 10 years down to months, maybe even weeks and perhaps even days one day And and then I think then all disease could be in reach And I think things like personalized medicine will become possible like personalized variations off of base medicines So I think the whole medical area drug discovery areas is going to be revolutionized in the next few years Brilliant. You talked a lot about AI for science. Do you think that at some point AI will create new sciences, a la Industrial Revolution and thermodynamics? Will there be something new, taught fundamentally in our education system? And if so, what would it be like? Well, I think there's several things along those lines that I think is going to happen. So first of all, the understanding and the analysis of AI systems themselves, I think, is going to become a whole science, a kind of engineering science. These are incredibly interesting artifacts that we are building. and they're incredibly complex as well. As complex, eventually they'll be as complex as the human mind and the brain. And so they'll need to be studied so we can understand fully, way beyond where we are today, how these systems work. So I think there's a whole kind of field, Mechinterp is part of that but there a lot more I think that we can do to analyze these systems So that would be a science But I think also AI itself will maybe unlock new sciences which is maybe what you getting at The one I'm particularly excited about is AI for simulations. So I love simulations. All the games I wrote not only had AI, but they were simulations. And I think simulations is the way we can address some of the what we maybe think of social sciences like economics and other more humanistic subjects because it's very difficult to do control studies in that you know why aren't they just sciences like physics today because the problem is they're emergent systems just like biology actually and it's very hard to do repeated controlled experiments you know if you're raising stress rates by half a percent you have to do it in the real world and then see what happens you can have theories, but you can't run it thousands of times. But if you could simulate things really accurately, then maybe there's sort of new sciences to be done where you can sort of rigorously sample from a very accurate simulator. And then I think that will allow us to make much better decisions in these today, very uncertain domains. What will it take to get to those extremely accurate simulations? World models, what kind of science is necessary?
[15:00] Yeah, well, look, I mean, I'm thinking a lot about that in, we do a ton of that work, like learning simulators, basically what it would be. So, you know, these are in domains where you can't, we don't know the mathematics of it well enough or it's perhaps too complex. We can't just write, we can't just write a directly down a special case simulator. It's just not accurate enough, doesn't capture all the variables. We're doing that, we've done it with weather. We have the most accurate kind of weather simulator in the world, Weather Next, and it's far faster than what the meteorologists use. Can you change the weather yet? No, we can't. We can't, no. And I'm not sure that would be a good idea. But the first step is to understand it better. But then even biology, you know, we're working on a kind of what I call a virtual cell. So a hugely dynamical emergent system. And I think biology is is perfect. Sort of machine learning is perfect description language for biology in the same way maths is for physics, because I think in biology and in lots of these natural systems, you have loads of weak signals, weak correlations, tons of data, far too much that any human mind can analyze. But there are connections and correlations and interesting causalities within that mass of data So I think it sort of it always struck me that machine learning is the perfect tool to describe those kinds of systems where until today you know mathematics hasn been able to do that either because we can't manage it as top mathematicians because it's too complex or the expressive power of math is not enough to understand these sort of highly emergent dynamical systems. Is it also because of the messiness and stochastic nature? Yeah, sure. And I mean eventually you could – by the way, once you learn these simulators, it may be there's – this is maybe another branch of – new branch of science. You could maybe extract some equations from – once you have the simulator. So you have this sort of implicit simulator or intuitive simulator and then maybe you could extract explicit equations from that because – partly because you could also sample it as many times as you want. As fundamental as Maxwell's or something like that. Maybe. I don't know if that exists for such emergent systems, but if they do exist, I don't see why we won't be able to find them with these methods. That would be amazing. You've talked about this theory that the basic building block of everything in the universe could be information This is more theoretical How do you think about that and what does that mean for a traditional classical Turing computer Well look I think you can of course all the famous, you know, equals mc squared and all the stuff Einstein did and energy and matter are kind of equivalent. But I actually think information has a kind of equivalency in the same way. So you can think of, you know, the organization of matter and structure and especially things like biology that are resisting entropy as basically information processing systems at their heart. So I think one can convert all of those three kind of quantities into each other. But I have this feeling information is most fundamental. So it's a little bit the opposite way around to the classic physicist thought in the 1920s and things where, you know, it's sort of energy and matter primary. I actually think it's a better way to understand the world, the universe, is to think about it as information first. And if that's true, and I think there's quite a lot of evidence for that, then of course, AI is even more sort of profound in a sense than we think. And it's already pretty profound because it's also about organizing information and understanding information and constructing informational objects So AI in my opinion is all about information processing so I think there something sort of very deeply connected with with uh these different areas If you think of it through the lens of information processing as the primary way to think about it And do you think a classical Turing machine will be able to compute everything? Well, I sometimes think, you know, I sometimes sort of think about what we're doing and refer to ourselves as Turing's champion because Turing machines, I think Alan Turing is one of my all time, you know, favorite scientific heroes. I think what he did obviously laid the foundations for the computers for computer science, but also AI. And I think it's one of the most profound results ever is the Turing machine result. You know, everything that is computable can be computed by a relatively simple description of a machine. So I think our brains are likely to be approximate Turing machines. And I think it's interesting to think about the connection between Turing machines and quantum computers and quantum systems. But I think at least what we've shown with things like AlphaGo and especially AlphaFold is that a classical Turing machine, obviously in the guise of a modern neural network, it can model what was thought to be in the case of protein folding, it's a quantum system, you know, at some sense.
[20:00] It's dealing with very small particles, and one might think you'd have to take into account all the quantum effects of the water bonds and all sorts of things. But it turns out you can get to an approximate optimal sort of solution on a classical system. So it may turn out that a lot of things that we think that would need a quantum system to model or run might be modelable on a classical system if you thought about in the right way. So you've talked about AI consistently as a tool, like a telescope or a microscope, astrolabe through the centuries. But when you think about a machine that can model almost anything, let's say it can even model quantum systems, like you pointed out, when does it stop becoming a tool? And will that ever happen? Well, my strong feeling is we should, in this sort of mission and journey to build AGI, those of us on that journey, many people in this room, I feel like it would be best to build a tool first an incredibly intelligent and useful and precise tool and then cross the next sort of Rubicon That already profound enough And of you know of course the tool could start becoming more and more autonomous and agent like that we all seeing We're in the midst of that, the agent era now. But then there's a further step of like, you know, does it have agency? Is it conscious? These sorts of questions, which are also going to be questions we're going to need to address. But I would recommend we do that as a second step, perhaps using the tool in the first step to help us with those next profound questions. And ideally, also, we could understand our own brain and minds better and define things like consciousness a lot more precisely than we can today. Do you have estimations of what that definition of consciousness might look like? No, I mean, I haven't got much to add beyond that thousands of years of philosophy hasn't said already. But I mean, it's very clear to me that it's obvious some components are going to be needed. They're probably necessary, but not sufficient. Things like self-awareness and, you know, the idea of self and other, some kind of continuity over time. So some of these things are clearly needed for anything that might look like consciousness. But I mean, obviously it's an open question as to what the full definition is And I talked to many of the great philosophers about that Daniel Dennett obviously sadly passed away recently but we had a long conversation a few years back about this And I think, you know, one of the issues is how does a system behave? Does it behave like a conscious system? So that's, you know, you could argue some of the AI systems might end up being able to do that as they get close to AGI. But then there's still the question of why do you, you know, why do we think each other are conscious? one is the way we're behaving we're behaving like conscious beings but the other thing is we're running on the same substrate so i think if both those things are true then it's parsimonious to imagine you're you're experiencing the same thing i'm experiencing which is why we don't have that debate uh about you know normally about are each other conscious but i think we'll obviously we'll never have the substrate equivalence with an artificial system um so they'll always be a i think it will be hard to completely close that gap. So you can look at it behaviorally, but what about experientially? There are probably some ways to do that post-AGI, but maybe it's a bit about out of scope today, even for AI for science discussion. Brilliant. So we're going to open the room to questions in just a moment get your questions ready But you brought up philosophers You mentioned Kant and Spinoza as two of your favorite philosophers Kant is this deontological highly duty philosopher Spinoza almost has this deterministic view of the universe. How do you kind of connect those two beliefs, and where is your thinking of how the world works? Well, the reason I like those two, they stuck out for me, is that I think Kant, when I was doing my PhD in neuroscience, you know, his sort of statements about the mind creates reality, right? I think that's basically true. And so another reason to study the mind, right, and how the brain works. And I'm interested ultimately in the nature of reality. So we have to understand how the mind is interpreting that. And so I think that's for me what I took from Kant. And then Spinoza, it's more about the you could almost call spiritual dimension of like, well, if you're trying to understand the universe using science, in my case, as the tool, you're sort of understanding some deep mystery about how the universe works. in a really kind of deep way. And that's what I feel we're doing and I'm doing when I do my science and we work on AI and we're building these tools is somehow we're kind of reading
[25:00] language of the universe. Beautiful. What a beautiful way to say what you do every day. Demis, scientist, orator, and philosopher. We will, before we wrap, do a couple of rapid fire questions. Thank you for finishing. He's not seeing these yet. Over, under, on distribution, year of AGI. Oh, wow. Or reject premise of question. No, 2030. I've been pretty consistent about that. Okay, 2030. Must read book, poem, or paper for when we achieve AGI? Oh, wow. For when we achieve, once we achieve it. Well, my favorite book is The Fabric of Reality by David Deutsch. So I think that still holds. I'd hope to answer the questions in that book with the AGI. That's my post-AGI work. Brilliant. Proudest moments so far in DeepMind? uh oh wow um we've been lucky to have a lot i mean probably alpha fold okay yeah now a couple games questions if you were engaged in a high stake strategy game turn-based strategy game okay uh civ polytopia serious games uh and you could select one scientist from history we're thinking the the einsteins the turing's newton's who would you select to be on your team On my team? On your team. Oh, gosh. Probably von Neumann, I think. Great choice. Yeah, you want a game theorist, I think. And I think he's the best. Makes sense. I feel like he'd be a good teammate. All right. Well, Demis, you do it all. Thank you so much for being with us. Please join me in taking a time. Thanks, everyone. Thank you.
