When I start to feel overwhelmed by the climate challenges we face, I turn to Hannah Ritchie, a researcher at Our World in Data. Her data-driven approach is an essential antidote to environmental doomsday-ism and provides some much-needed optimism about humanity’s ability to tackle big problems. I recently sat down with Hannah to talk about her terrific new book Not the End of the World, why it’s so hard to wrap our minds around human progress, what we would ask a time traveler about the future, and more.

If you ask people to name leaders in artificial intelligence, there’s one name you’ll probably hear more than any other: Sam Altman. His team at OpenAI is pushing the boundaries of what AI can do with ChatGPT, and I loved getting to talk to him about what’s next. Our conversation covered why today’s AI models are the stupidest they’ll ever be, how societies adapt to technological change, and even where humanity will find purpose once we’ve perfected artificial intelligence.

Few people are better at explaining the science of artificial intelligence than Yejin Choi. She’s a computer science professor at the University of Washington, senior resource manager at the Allen Institute for AI, and the recipient of a MacArthur Fellowship. I thought her recent TED talk was terrific, and I was thrilled to talk to her about how you train a large language model, why it’s so hard for robots to pick tools out of a box, and why universities must play a key role in the future of AI research.

I recently started learning French, and the process has made one thing clear to me: There’s a lot I don’t understand about how languages work. So, I turned to John McWhorter, a linguist who has dedicated his career to demystifying the roughly 7,000 languages spoken around the world. When he isn’t busy writing books, John is a professor at Columbia University, host of his own podcast, and frequent lecturer for Great Courses. He helped me understand why English is so irregular, what the ideal language would look like, why all dialects are created equal, and more.

Ahmir “Questlove” Thompson is the ultimate multi-hyphenate: He’s a musician, filmmaker, author, entrepreneur, and more. The Grammy and Oscar winner is also a plant-based foods advocate, so when I had some questions about the future of food, I knew I had to sit down with him. We had a blast talking about why he made a meatless Philly cheesesteak, how we make healthy food accessible to more people, Questlove’s insane record collection, how we got our nicknames, and our Wordle strategies.

Sal Khan is a true pioneer of harnessing the power of technology to help kids learn. So, when I wanted to learn more about how artificial intelligence will transform education, I knew I had to talk to the founder of Khan Academy. I loved chatting with Sal about why tutoring is so important, how his new service Khanmigo is making the most of ChatGPT, and how we can keep teachers at the center of the classroom in the age of AI. We even found time to talk about our favorite teachers and the subject we wish we’d studied in school.

Can Alzheimer’s disease be funny? I was skeptical, especially given the devastating experience my family had watching my dad suffer from it. So, I asked two experts in using humor to raise awareness—Seth Rogen and Lauren Miller Rogen—to help me see the light. We had a great conversation about their organization Hilarity for Charity, hope for the future of Alzheimer’s research, the importance of a good night’s sleep, and why Seth started a cannabis lifestyle company.

What do you do when you can’t solve a problem? I like to talk to smart people who can help me understand the subject better. I call this process “getting unconfused”—and I think it is one of the best ways to learn something new. In my new podcast, I try to get unconfused about some of the things that fascinate me. Join me on my learning journey as I talk to brilliant guests about Alzheimer’s disease, marijuana, plant-based meat, the evolution of language, and more. Episode 1 with Seth Rogen and Lauren Miller Rogen will be available starting on July 27, 2023.
