Ep167 "What Happens With Stone Age Brains + Godlike Tools?" with Steven Kotler
Ep167 "What Happens With Stone Age Brains + Godlike Tools?" with Steven Kotler Aug 17, 2026 2310 What happens when old brain circuitry collides with modern tech? Are we heading into an age of abundance, and can abundance create its own psychological problems? Do we need friction in our lives to become better humans? Could curiosity become the most important survival skill of the twenty-first century? What happens to your biological neural networks when artificial neural networks do your think
Ep166 "Could the Next Brain Interface Get Sprayed Up Your Nose?" with Tetiana Aleksandrova & Scott Meek
Ep166 "Could the Next Brain Interface Get Sprayed Up Your Nose?" with Tetiana Aleksandrova & Scott Meek Aug 10, 2026 2876 A brain computer interface (BCI) is any technology that allows you to connect your 3 pounds of wetware to a computer. But instead of implanting electrodes via neurosurgery, might the next revolution in BCIs come from something very small, like nanoparticles? Would this allow us to spy on millions (or billions) of neurons talking at once -- and could we do so without opening the
Ep165 "What's a Doom Loop & How Do You Escape It?" with Jonathan Downar
Ep165 "What's a Doom Loop & How Do You Escape It?" with Jonathan Downar Aug 3, 2026 3592 Have you ever spent hours with a thought cycling around in your head? What happens when the brain continuously worries, craves, or replays something without finding the exit? Where does the feeling of being “done” come from? Might depression, addiction, OCD, and PTSD all share the same problem? Is mental freedom just the ability to change states? Join Eagleman with neuroscientist
Ep164 "Why Do We Act Differently Around Different People?" With Claude Steele
Ep164 "Why Do We Act Differently Around Different People?" With Claude Steele Jul 27, 2026 4268 Does your identity and performance change in different situations? What does this have to do with wondering how you’re being judged? What if polarization grows from uncertainty more than hatred? Might social uncertainty be more common than prejudice? Why do strangers become enemies so easily? Can we engineer more trust into society? Today Eagleman sits down with Stanford social psycholo
Ep163 "How Quickly Does AI Become Smarter Than Humanity?" with Ben Goertzel
Ep163 "How Quickly Does AI Become Smarter Than Humanity?" with Ben Goertzel Jul 20, 2026 4169 What is artificial general intelligence (AGI) and how close are we to getting there? What defines the next step, called artificial superintelligence (ASI), and why might the gap between those two be so dangerous? When machines become smarter than us, what roles are left for humanity? Should we think of AI as software, or as something we’re raising like a child? Will tomorrow’s AI
Ep162 "What Does Medicine Look Like in Ten Years?" with Jeanne Loring
Ep162 "What Does Medicine Look Like in Ten Years?" with Jeanne Loring Jul 13, 2026 2025 For all of medical history, we’ve tried to persuade sick cells to behave better. What if instead we just swapped them out? Can we insert new brain cells grown from your own skin cells? And what does any of this have to do with sending one’s own cells into space, or rescuing animals on the very brink of extinction? Today we talk with stem cell biologist Jeanne Loring about the
Ep161 "What Do Ancient Brains and Future AIs Have in Common?" with Read Montague
Ep161 "What Do Ancient Brains and Future AIs Have in Common?" with Read Montague Jul 6, 2026 3802 What do honeybee brains have in common with human brains -- and with the AI that beat the world's best Go player? What simple algorithm has been hiding inside brains for 100s of millions of years? When babies throw food from a high chair again and again, are they being mischievous or are they running physics experiments? And what does any of this have to do with whether dopamine is more than a ple
Ep160 "Do You Really Have a Self?" with Sam Harris
Ep160 "Do You Really Have a Self?" with Sam Harris Jun 29, 2026 3996 re you the author of your thoughts or just their witness? Do we simply watch our thoughts like we watch unfolding dream plots? What if the most familiar thing you experience — yourself — isn’t really there? If that’s the case, why does the experience of the self feel so solid that it often takes a lifetime to notice something strange? Why would evolution invent the feeling
Ep159 "If Your Brain Changed Slightly, Would You Still Be You?" with Masud Husain
Ep159 "If Your Brain Changed Slightly, Would You Still Be You?" with Masud Husain Jun 22, 2026 4333 Could a tiny injury to your brain change your personality? If your friends didn’t know something had happened in your brain, would they just think you're choosing to act strangely? What if the self is nothing but a fragile coalition of neural processes? Join Eagleman today with Masud Husain, a neurologist and neuroscientist at Oxford, to explore fascinating case studies about how change
Ep158 "What do babies, animals, and AI have in common?" with Melanie Mitchell
Ep158 "What do babies, animals, and AI have in common?" with Melanie Mitchell Jun 15, 2026 2722 When AI gets the right answer, how do we know it got there the right way? Why do we assume that fluent language means intelligence? What do infants and chatbots have in common? What do AI’s mistakes teach us about our own minds? And what does any of this have to do with Frankenstein’s creature, why some people wear a stop sign on their T-shirt, or smiling monkeys? Join Eagleman today w
Ep157 "Where Did the Letter "A" Come From?" with Danny Bate
Ep157 "Where Did the Letter "A" Come From?" with Danny Bate Jun 8, 2026 3215 How can we use 26 symbols to capture everything in the cosmos of human experience? Where do our written symbols in English come from? What ancient ghosts are still hiding inside the letters you read every day? Does learning to read reconfigure the circuitry of your brain? Does dyslexia reveal how unnatural reading really is? And could AI freeze the evolution of language for the first time in histo
Ep156 What Do We Learn About AI by Dancing with Robots? with Catie Cuan
Ep156 What Do We Learn About AI by Dancing with Robots? with Catie Cuan Jun 1, 2026 4346 Why do we read so much into how a robot moves, and what does that tell us about human brains? Why did our history make us so sensitive to movement? Why do we trust graceful motion? Should we make a robot 'look' at an object it’s about to pick up, even if it doesn’t need to? Is movement the original form of animal intelligence? Join Eagleman with guest Catie Cuan, a roboticist, dancer,
