Ep132 "What will AI mean for the economy?" with Andrew Mayne

If AI can do everything from writing novels to designing proteins, what remains that only humans can do? What's the human advantage in a world where machines can outperform us at almost any measurable task? What does any of this have to do with Stephen King’s nightmares, Tom Cruise’s stunts, the fi…

Ep131 "What do brains tell us about politics?" Part 2: Rehumanization

How do societies work their way out of polarization? And what does the answer have to do with broken trucks, the Apollo program, the movie 'Watchmen', Iroquois Native Americans, a new idea for social media algorithms, moral taste buds, and how we can take advantage of the common threads that bond u…

Ep130 "What do brains tell us about politics?" Part 1: Polarization

What do propaganda posters have in common across nation and time, and how is that related to the medial prefrontal cortex? What is behind repeating cycles of societal polarization? What does any of this have to do with the American Civil War, hippies vs soldiers, border ruffians vs free-staters, ha…

Ep129 "Is utopia possible or do human brains preclude it?" with Paul Bloom

Would a utopia be possible? Or does our innate tribalism and jealousy make perfect societies difficult to achieve? Do we secretly love hierarchies? Why are primate brains such excellent detectors of unfairness? Why do things become more desirable when we’re told we can’t have them? Did the church’s…

Ep128 "Would space aliens see the world as we do?" with Daniel Whiteson

Imagine we eventually meet some alien scientists. If they can see electrons or smell photons, would their science look like ours? Is physics a universal language, or just a local dialect of the human brain? Would aliens use math, or might their truths be organized unrecognizably? Are the “laws of n…

EP127 "What happens when we marry brains to machines?" with Sergey Stavisky

What is a brain-computer interface? How can a paralyzed person use her brain to control a robotic arm? How can someone who's lost the gift of speech use brain signals to broadcast his voice again? Can we eventually restore autonomy and dignity so seamlessly that the technology disappears and the pe…

Ep126 "Does science fiction shape reality?" with Bethanie Maples

How is sci-fi like a cultural research and development lab? Will we someday have AI agents that live in robot bodies, and will we be liable if they commit murder? What happens when reality is no longer verifiable? How can we create AI advocates that guide us toward self-actualization over distracti…

Ep125 "Why do brains need friends?" (with Ben Rein)

Why do human brains need social interaction? Why might AI chatbots be insufficient to scratch the itch? What do we love so much about real human touch and in-person interaction? Why do so many of us live with dogs? From empathy to introversion to social media to isolation (and what to do about it),…

Ep124 "Why don't we notice gaps in time?"

How is your consciousness like a flame that continually goes out and gets re-lit? Why can you see other people's eyes move, but you can't see your own eyes move in the mirror? And what does any of this have to do with deep sleep, anesthesia, comas, amnesia, and empires of soft-bodied creatures that…

Ep123 "Will AI cure loneliness?" with Paul Bloom

On the one hand, AI companions are (increasingly) amazing at rectifying isolation. But on the other hand, loneliness is a biological signal that pushes us toward improving ourselves socially. So what's the right balance here? And does everyone have the same need to cure loneliness? In other words, …
