This week on the show, we're sharing Reid Hoffman's conversation with Dr.

1:10Fei-Fei Li from our 2025 Masters of Scale Summit. Fei-Fei is a brilliant computer scientist and author who has been at the forefront of AI development for decades. She was a founding director of Stanford's Human-Centered AI Institute and is now the co-founder and CEO of World Labs. She joined Reed on stage for candid reflections on where we are and where we're headed as AI evolves. I think you'll enjoy this.

1:53I've lost count of the number of times we've done this, and it's always awesome and an honor. So thank you for being here. Thank you. I've lost count, too. Obviously, anyone who's following your career knows that you're one of the OG in the way of AI, ImageNet, all of these things that are contributions that are fundamental to where we are today. So, by the way, thank you for that. And now you're working on spatial intelligence and world building. Say a little bit about why you took a sabbatical from a job you love with human-centered AI and Stanford CS and started building this company and what you're doing.

2:31So, you know, Reid, you are one of the original supporters, investors of OpenAI. So when OpenAI was founded, you and I talked about the dream of AGI, right? As an AI scientist, I'm torn between the word AI versus AGI because they more or less mean the same thing for me. But language aside, what is... Actually, I use AGI for the AI we haven't invented yet. Okay. Yes. So what is AGI to me? AGI to me is the capability of intelligence, of machines that are on par with humans and in many cases can be superseding humans. And I think about this as a door to the future. And on this door, there are multiple keyholes.

3:18and language is one of them, one of the major ones, because language is an essential part of intelligence to the point that I know you are a quasi-philosophy major, that Wittgenstein... Quasi is actually a positive word. At Stanford, I have to say, because Reed is an alumni, there is a very special major called symbolic systems. They combine philosophy and cognitive science and computer science. By the way, I was the eighth person to declare that major. Oh my gosh, so many famous people come out of that major. Yeah, so quasi, it just means the proportion, so it's a good word. She'll correct me later, but that's all right.

3:59I'm digging myself out of a hole.

4:05Wittgenstein says that language defines the limit of world. I'm actually disagreeing with that. Excellent. Because I think language defines a certain level of boundary that the world can be described in symbolic forms. But beyond that, the world is actually limitless. And what is that world? How do we define that? What does that have to do with intelligence? How do we use machines to express that? I love that whole thing in world modeling. World modeling is very connected to language, but it's about expressing, representing, and eventually participating in the changes of the state of the world.

4:49And that could be virtual, it could be physical. And what does world modeling entail? It does entail language, because language is one form of interrogation with the world. But it also entails the visual, the lights, the semantics, the space, the physical actions, and all of that is still at the dawn and it's the next phase of AI. And that's what World Labs is about. We are trying to do world modeling and we're trying to bring that level of spatial intelligence into the next chapter of AI. So two questions with the spatial intelligence. One, because there are a few people who will be deep here, but a lot of people, their primary experience of LLMs is like Chachi, BT, Gemini, etc.

5:32So what should they understand is different, not just in the cognitive capabilities, because our world is not just language. And then two, what does the road ahead look like? What are some of the challenges to overcome in getting there? Yeah. What would it get us when we have world modeling? Well, we're already seeing budding signs of that. Lots of storytellers are creatives with many media, right? Whether it's pixels, movies, sculptures, digital art. And that is a highly, highly creative interactive world that you cannot just use language to express and world modeling the ability to generate things to generate worlds that you can immerse yourself in you can interact with is highly enticing and exciting for for creators and that's one way you see world modeling could be applied for.

6:30This is not just for entertainment and storytelling. This could be for design, could be for even industrial uses, all the way to healthcare, medicine, education. Also, the distance between being passively entertained and being actively participating in experiences right now has been closing rapidly. And the ability to have machines to create world models that would allow that kind of immersive experiences is really powerful. And that also segues into simulation. Simulation is really important both for human experiences, human learning, as well as for embodied AI. Robots need to learn from simulation as much as it needs to learn from the real world.

7:17We can really learn about the history of robots, including self-driving cars and the critical roles that simulation has played. So the application really is boundless. What are the challenges? I'll just call out one challenge. There are actually many challenges. One challenge is data. Unlike language where data is all over the internet, when it comes to world modeling, data is not as obvious and easily obtainable compared to language. Of course, there are video data. That's one of the most critical form of data for world modeling. But the world, like I said, is very multi-model. It's very spatial.

7:59It has fundamental 3D information, geometry, physics, dynamics. And some of those are not easily obtainable. And so there's always been a lot of discussion around robotics. And one of the things I think we should draw the line for everyone is to understand how critical world modeling will be to any kind of robotic elevation of work and human conditions. Say a little bit about why this cognitive set is so important there. Yeah, I spent a lot of time thinking about that because, frankly, after ImageNet, after the first wave of computer vision achieving a level of fidelity and quality, I actually went into a little bit of a crisis myself and started to soul search.

8:47What is perception about? What is vision for? I thought it would take me 100 years to work on the problem of object recognition, but it went a little faster than I thought. So I needed another North Star. And it took me back to evolution. And I started to read a lot about evolution. And I'm like literally this much of a philosophy student compared to Reed. is that about 530 million years ago, there was an incredible evolutionary event called Cambrian Explosion where the animal speciation just exploded, where it's also the beginning of the nervous system, the beginning of photosensitive cells. And it really, after reading a lot of literature and thinking, it really dawned on me the goal, the evolutionary reason animals have perception is actually for activity for interactivity it's active and that means perception and the perceptual intelligence is the foundation of movement and the beginning the movement is very simple you just kind of translate your body somewhere quickly the movement becomes much more interactive and fighting for food, to mating, to nesting, to rearing offsprings, to much deeper.

10:13I mean, look at mammals and humans. Our ability to move is very, very complex. The degree of freedom we have between our fingers, toes, and body, torso is very high. And all this requires a fundamental perceptual, spatial intelligence of the world we're in so that we know, we understand, and we can plan for all the movements. So really, truly, in my opinion, that the level of nuanced, complex, spatial world understanding is the brain of embodied intelligence, including robots. And actually, while the robots give a particular sense where you need that embodied intelligence for them to all be embodied.

10:59There will also, of course, be, a little bit like your opening comment on Wittgenstein, the question of actual cognitive reasoning capabilities that are not just purely linguistic. Still ahead, more of Reed's conversation with Fei-Fei about why we should all be more fearless in the age of AI.

11:33Meet Nicole Nicholas, Capital One business customer and co-owner of Ansett Uncles, a plant-based restaurant and community space in Brooklyn, New York, that got its start from a need for unity. The inspiration, it was born from the desire to create a space that felt like home, where we can connect community culture, good food, and come together with family and friends. That's how we birthed aunts and uncles. Nicole and her husband, Mike, were fulfilling their dream of bringing people together out of their home kitchen. But they soon learned that the demand for community was greater than they knew.

12:04It became overwhelming and we were like, we need home, but not in our actual home. We realized that there was also a need in our community for something bigger in our neighborhood. So we had to find a place. Moving from a home operation into a storefront was a huge next step. But Nicole and Mike were able to take it on with the help of Capital One Business. It's not for the weak. As a small business, finding resources is super important because that's the way you'll be able to manage and scale. We would have never done that without having Capital One to be able to help us along the way. The cashback rewards are very helpful.

12:39You know, it just gave us that runway to be able to breathe a little bit. Then you get to focus on the cooking of the food and making the experience great.

14:41Part of what you get with spatial intelligence is other forms of intelligence that will even be important there. It isn't just in a pure perception-action loop. The old Western perception as a camera and action as separate is clearly wrong. That was the thing that you were just referring to. But it will also increase our cognitive capabilities, our like how we imagine the world, how we model it in our heads. What are some of the reasoning characteristics you think might come out from when you add spatial intelligence, not just to robots, but to every AI system? That's wonderful, Reid. This is why I love talking to you.

15:16So throughout human civilization, if you look at the milestones of humans building civilization, there is a lot of milestones that cannot possibly be achieved with just language. The nuance of space and spatial reasoning, world modeling, is very, very clear. For example, let's just take early days, the building of pyramid. The ability to start to abstract geometry, the sense of geometry, and also the construction of large bodies. there is a lot of things that goes on into that cognitive spatial reasoning that's not this simplistic transactional behavior of I see something I want to move it right another example is the deduction of the structure of DNA if you know the history of how DNA was discovered of course many scientists were getting a vibe using today's language that there's something there's something that's going on in this fundamental building block of our genetics but it took Rosalind Franklin under appreciated scientists to take this x-ray imagery but then Francis Crick and James Watson of course they were deeply thinking about this but to go from this imagery to a 3D double helix intertwined structure is deeply spatial.

16:53You cannot language your way into this deduction. I'm sure language participated. I'm not anti-language. I love Vicky Sky. I speak. I am pro-language. Exactly. But that is a beautiful example of humans using spatial reasoning and cognitive ability to do something or discover something we've never done. So I think that as we empower AI with this ability, this is not just for robots that can, you know, pick up glasses or a cube. This is for lifting all of humanity's capability because we can collaborate with machines having this capability. Yeah, awesome. And actually, I've never heard the DNA answer from you before.

17:43So I love asking you questions that I have never asked you before. There's a lot of discourse around, is AI overhyped, underhyped? We're obviously here in the Valley, so everyone in the Valley more or less thinks underhyped. People want to say, are we going to go through another AI winner? What's your view about this discussion about what's going on with AI? What would you say, hey, this is the parts that are underhyped. These are the parts that are maybe a little too soon. What's the guide to the wise on the current discourse and sorting wheat from chaff a little bit? Oh, boy, I have to be careful how I answer this question, but I totally appreciate this.

18:21AI is a civilizational technology. I'm not the only one saying this, but I truly believe because even if you're inspired by humans and evolution, this is the ability to intellectualize and to think, to do, is fundamental to humans. And a piece of technology that can do that is phenomenal. In my opinion, it's more or less not overhyped as an intellectual future of humanity, because AI is the new computing. If you look at today's world and just recognize where there are chips, you know, because chips are the physical places where computing happens. From a light bulb to a self-driving car to an airplane, everywhere there's chips.

19:13Well, it's very obvious at this point, wherever there is chip, there's compute. Wherever there's compute, there will be AI if it's not there. So from that point of view, both from a business as well as use case point of view, AI is the future. Obviously, when it comes to hype, I do think we have to be a bit nuanced. For example, it took more than 20 years to go from Sebastian Thrun's first self-driving car that can drive a car 130 miles in the Nevada desert, which has no traffic, apparently, to Waymo running in San Francisco, right well you might say well because part of it is software it was pre-deep learning stage and software development was slower you're right it's definitely deep learning accelerated the brains of self-driving car but let's also not forget that car industry the entire supply chain as well as customer use basis has been established for more than 100 years and it's a very very mature business model and very mature infrastructure and manufacturing and everything.

20:25So if it took 20 years to get just cars, which is the simplest form of robot on the street. Or Roombas. I was thinking, I knew he was going to say that. Well, Roombas are mini cars. Yeah, so robots actually, I think cars are, you know, it's literally a square-ish box that moves on a 2D surface, and the only thing you have to do is not to touch anything. Right, because if you touch, you're screwed. And Roombos does touch, and by and large, it's okay. But robots, the whole thing about robots is it's a three-dimensional machine that the whole goal is to touch things and touch it in the right way.

21:18I mean, this is huge. So I think there is still going to be a journey for robotics for sure. 100%. So one of the things to realize this civilization technology is to build trust. and whether it's technologists, companies, etc. What do you think the things we should be doing as leaders, as companies, as entrepreneurs to help build trust because it's obviously we only start realizing the real benefits once we get there? Great question. I know you and I both care about this. One thing I feel very strongly is in the AI age, trust cannot be outsourced to machines. Trust is fundamentally human. It's at the individual level, community level, and societal level.

22:06And this is why Reid was part of our supporters for the Human-Centered AI Institute at Stanford. We established that 2018, so way before this latest wave of AI blossoming, is because we recognize that as machines get more powerful in its computing and reasoning and eventually even actionable capabilities, we need to establish a new norm that needs to be part of the fabric of the society where within this norm, humans continue to have the agency to build trust with each other, with the newer tools like AI, with more powerful products like chatbots and other things. And eventually, this trust has to be renewed or updated into our governance model, not just the governance of community and companies, but governance of the society at large.

23:09So I do think trust is a very, very important element. For this audience, it's very entrepreneur-heavy. I would just say, care about this from the beginning, no matter what product or business you're doing. some of you might be in healthcare you know how important it is some of you might be just in the infrastructure, SaaS, whatever application that feels like maybe that's more removed, that's not true because you're serving people, you're serving businesses, trust is really important, have that human agency as the source of the trust. Yeah, 100 % and part of when yes

23:53you know part of the work that you know you and etch were leading with the human-centered ai which came from your new york times column is part of the thing that led me to focusing on agency is one of the things the elevation of human agency as one of the key things that we need to do so let's go to kind of the science side of it you've said it's important for scientists to be intellectually fearless. So what does that mean for how we should think about inventing the future? What does that mean for how science should progress? In terms of the next generation of innovators, where should fearlessness play into that?

24:32Well, if scientists need to be fearless, I think entrepreneurs need to be more fearless. Fearless to me, I love this word, and this is part of the way I actually do hiring is look for people, especially young people with that fearlessness. Fearless is to be free, to get rid of the shackles that constrain your creativity, your courage, and your ability to just get shit done. And pardon my language, it's actually... It's a technical term. Yes. It's actually in our core culture of our company. So, it's that, you know, humans are not exactly the most fastest, strongest, you know, animals on Earth, right?

25:22We were, if you look at many of the dimensions, I was just in Africa this summer with my kids. I mean, there's so many animals that are just so much better than us. But I do feel that way. Lots. Yes, but there's something that is in our brain, in our mind, in our soul that can propel us to do incredible things for the world, for ourselves, for each other. And a lot of that comes from our fundamental uniqueness of our creativity and our sense of community and all this. And in order to unleash that, especially as technology is moving so fast, to me, the foundational emotional criteria is be creative, be free.

26:15And that translates into be fearless, run into uncertainties, run into bold ideas that no one has made it happen yet, run into contrarian hypotheses, run into hard tasks. Someone said, I forgot who said that. Tasks that are so certain versus tasks that are uncertain are sometimes equally hard. choose the one that's more uncertain because your creativity will be working harder and that's where the magic happens so i love the word fearless because that's where boundaries are broken and creativities are unleashed and uh and magical things happen and

27:08And with that, you can see why we wanted to open the first Fireside with Fei-Fei. Let's give her a hand. Thank you. Thank you.

27:22Thanks to Dr. Fei-Fei Li for joining us at the Masters of Scale Summit. This conversation was recorded on stage at the Presidio Theater in San Francisco.

27:43Meet Emily Warden, Capital One Business customer and owner of Emily Warden Designs, a handcrafted fine jewelry store in Richmond, Virginia that got its start in a dorm room. I said I was going to try it for a year. I signed up to do craft shows, trade shows, got into a few local boutiques, and then things just picked up from there. Emily's steady success at trade shows gave her the capital she needed to invest in a storefront. Every cent that was made was going back into the business. I was nervous that we weren't going to get enough traffic, but we had a huge turnout. With Emily Warden Designs firmly establishing itself in the Richmond community, Emily would need to significantly increase inventory in order to keep up with demand.

28:25and she looked to her Capital One business card for support. The purchases were so high, I needed to get a business credit card. And I looked at Capital One, the options and the cash back was so amazing. It gives me even more of a push to take a leap in getting one or two extra stones because I have that extra cushion. To learn more, go to CapitalOne.com slash business cards. One of the patterns I've seen over and over in speaking with successful founders is this. They don't wait for HR problems to show up. They build solid systems early on so their company can grow without tripping over itself.

29:09JustWorks is one of those systems. JustWorks is the human resources platform that helps you scale without sacrificing your team's needs. It handles automated payroll, benefits, compliance, even international hiring, so you can scale your team without slowing your momentum. JustWorks secures your hiring systems so they don't cost you time, money, or people, which is how you scale with confidence. JustWorks for your people. Every company that scales has that moment, the one that could have gone either way. We all remember the choices that shaped the course of our lives. And in business, world-renowned venture capital firm Sequoia Capital calls them Crucible Moments.
