Lex Fridman Podcast

Lex Fridman’s podcast has become almost synonymous with long-form AI conversation. An AI researcher with ties to MIT, Fridman started the show in 2018 and has since produced nearly 500 episodes, pulling in guests from across science, technology, philosophy, and beyond. The AI episodes remain the beating heart of the show. The format is simple: Lex sits down with one guest for an extended conversation, often running two to four hours. He has talked with virtually every major figure in AI, from Demis Hassabis and Yann LeCun to Sam Altman and Ilya Sutskever. His interviewing style is patient and methodical. He asks big, open-ended questions and then lets people talk. Some listeners love the contemplative pace; others wish he would push back more. Either way, the depth is unmatched. Recent episodes include a sprawling State of AI in 2026 discussion covering LLMs, scaling laws, agents, and AGI timelines. The show carries a 4.7-star rating from over 12,000 reviews on Apple Podcasts, making it one of the most popular podcasts in any category. For AI specifically, the back catalog alone is an incredible resource.
