Inner Cosmos with David Eagleman iHeartPodcasts

David is taking his birthday week off and wanted to re-share this episode due to it's ongoing relevance.

Modern AI is blowing everyone’s mind. But is it intelligent like humans, or is it just playing impressive statistical games? Could AI reach or exceed our level of intelligence, and how would we know when it gets there? Traditional tests for intelligence (Turing test, Lovelace test, etc) have long been surpassed, so Eagleman proposes a new kind of test. 

Why does a cold pool feel warmer the second time you dip your toes in? Why does a safecracker run his fingers over sandpaper? Why do Mediterranean cultures touch each other more than Scandinavian cultures? Would it be great -- or not so great -- if you were unable to feel physical pain? Why does stubbing your toe have different sensations through time? And what does any of this have to do with cuddle puddles, NBA players bumping chests, or puppies sleeping in dog piles? Today’s episode is a love story about our sense of touch: what it is, how it works, and why it plays such a critical role in our lives.

Could you instantaneously learn to fly a helicopter -- not by practicing, but instead by uploading instructions directly to your brain? What would society do if children no longer had to go to school? And what does any of this have to do with suntan booths, nanorobots, or what a cowboy on a hill is not able to see? Join Eagleman to learn about the possibility of modifying the microscopic structure of your brain and leapfrogging education. What are the possibilities, the caveats, and the unexpected complexities?

From the brain’s point of view, what is the self? How do 30 trillion cells come to feel like a single entity? Does the "self" of a blind person include the tip of her walking stick? How flexible is our sense of self? And what does any of this have to do with psychedelics, trauma, synchronized swimmers, religious rituals, cheerleaders, or why soldiers across time and place love to march in lockstep? Join Eagleman for this week's episode of surprises about how the brain computes the self.

Presumably we're not going to solve the problem of conflict between groups of people -- but what would better conflict look like? And what does that have to do with brains, the spread of homo sapiens, social media recommender algorithms, tribalism, intellectual humility, or the Iroquois Native Americans? Join this week's episode with guest Jonathan Stray -- a conflict researcher -- for an episode about brain science, war, empathy, outgroups, and how we might do better.

Can you become conscious inside a dream? Can a researcher convey information to a dreamer, and can the dreamer find some way to answer back? Does 10 seconds inside a dream equal 10 seconds in real life? Could taking a drug inside a dream give you a placebo effect? Can you prompt your brain like a large language model? And if so, what would you pose to your unconscious brain? Join David Eagleman and guest Jonathan Berent to discover the what, why, and how of lucid dreaming.
