The Case for AI Optimism with Peter Diamandis and Steven Kotler Jun 11, 2026 3987 Nearly half of all Americans believe AI is bad for humanity. Peter Diamandis is not one of them. On his podcast, Moonshots, and in his new book, We Are as Gods, co-written with the inimitable Steven Kotler, he makes the case that artificial intelligence is already ushering in a world of abundance — think radical life extension, 10 billion humanoid robots, and agents that do your job while you're s
Best Of: The Power of Thinking Outside Your Brain Jun 8, 2026 4369 Modern life has not been easy on our brains. Average IQ scores rose steadily throughout the last century. Now they appear to be leveling off. The problem, according to neuroscientists, may be that we have reached our neurobiological limits. Our brains simply can’t work any harder. Luckily, science writer Annie Murphy Paul has a solution. In her book The Extended Mind: The Power of Thinking Outside
Want to Be Happier? Try Talking to Strangers. Jun 4, 2026 4600 Nicholas Epley is a mind reader. But he doesn’t have ESP or practice hypnosis. He's not telepathic or clairvoyant. Sure, you could ask him to read your fortune, but you'd be better off with a Magic 8 Ball. When we say Nick is a mind reader, what we mean is he studies mind reading at the University of Chicago — studies, as he puts it, "how we make inferences about each other's thoughts and belief
Best Of: Gretchen Rubin’s Guide to Getting Out of Your Head and Into the World Jun 1, 2026 3272 What do your five senses — sight, sound, smell, taste, and touch — have to do with happiness? According to Gretchen Rubin, a great deal. The world around us, she says, has the potential to dazzle, to entertain, to trigger a state of rapture. If only we pay attention. Today on the show, she shares the tools she's developed to delight in the physical world. She spoke to Rufus in April 2023 about her
The Case for Speechmaking in the Age of Doomscrolling May 28, 2026 3994 America's a funny place. It's not a country with a fixed geographic or religious identity. We don't have a common story of divine creation. "What we have," writes Ben Rhodes in his new book, ⁠All We Say⁠, "are words." The words of the founding documents, yes — but also "the words of speeches spoken by Americans who call us to be that better version of ourselves." Ben has spent more time with grea
Best Of: Stop Chasing More. Start Embracing Your Limits. May 25, 2026 4769 In his mega-bestseller Four Thousand Weeks, Oliver Burkeman showed that the finitude of life “isn’t a reason for unremitting despair, or for living in an anxiety-fueled panic about making the most of your limited time. It’s a cause for relief.” In his follow-up book, Meditations for Mortals, he invites us to embrace what he calls “imperfectionism.” Accept your limitations, your finitude, your lack
When Will AI Empty Your Dishwasher? (with Nicholas Thompson) May 21, 2026 3245 Nicholas Thompson, CEO of The Atlantic and host of "The Most Interesting Thing in AI," joins Rufus and Caleb to explain why the machines may master our minds long before they master our muscles — and what that gap tells us about where AI is headed. Along the way: why human podcasters still beat AI ones, how Nick learned to stop worrying and love open source, and where he'd point an infinite AI bud
Best Of: An Epicurean Guide to the Good Life May 18, 2026 4292 The Greek philosopher Epicurus made a rather bold claim over two thousand years ago. The key to life, he said, is simple: pursue pleasure and avoid pain. Around this maxim he developed a school of philosophy, Epicureanism, which promised its adherents that if they took care of their basic needs, surrounded themselves with trustworthy friends, and developed a basic understanding of science, they wo

You Can Grow Your Brain. Here’s How. May 11, 2026 4813 In the last 20 years, there has been a dramatic change in our understanding of neuroplasticity — the brain’s capacity to grow new neurons. In the last five years, we’ve learned that your hippocampus, the part of your brain responsible for learning and memory, can get bigger at any age. Majid Fotuhi, who teaches at Johns Hopkins, has been at the forefront of a new body of research demonstrating tha

You're in the Hospitality Business (Whether You Know It or Not) May 4, 2026 3785 For the last three years, Will Guidara has been on the road talking about unreasonable hospitality. He's met financiers and prison wardens, educators and athletes, Fortune 500 executives and small business owners.
