Inner Cosmos with David Eagleman

Ep166 "Could the Next Brain Interface Get Sprayed Up Your Nose?" with Tetiana Aleksandrova & Scott Meek

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 skull? Will this allow BCI tech to become as common as smartphones? Join Eagleman as he talks with the company Subsense about why the next brain-computer interface might come from thinking small.

Ep165 "What's a Doom Loop & How Do You Escape It?" with Jonathan Downar

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 and psychiatrist Jonathan Downar to talk about doom loops and how we might break them.

Ep164 "Why Do We Act Differently Around Different People?" With Claude Steele

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 psychologist Claude Steele to explore the hidden psychological forces that shape who we become whenever we wonder how other people see us.

Ep163 "How Quickly Does AI Become Smarter Than Humanity?" with Ben Goertzel

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 destroy us, ignore us, or protect us? This week Eagleman talks with computer scientist & AI researcher Ben Goertzel.

Ep162 "What Does Medicine Look Like in Ten Years?" with Jeanne Loring

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 exciting next horizons.
