Lex Fridman Podcast
Long conversations about consciousness, code, and love
157 episodes from 11 Jan 2023 – 26 Aug 2026 · 468 hours.
What it is
Lex Fridman sits down with researchers, engineers, historians and occasionally heads of state, and lets it run — some episodes pass ten hours. The register is earnest and the questions are broad: consciousness, war, love, what a life is for, alongside the technical detail of whatever the guest actually builds.
Who's on it
Hosted by Lex Fridman. Guests skew toward AI and the sciences, with a strong recent run of long-form history.
What it's good for asking
- What have guests said about AGI timelines?
- How do guests describe the risk of AI?
- What was said about the Roman Empire?
Questions are answered only from these episodes' transcripts, and every answer cites the episodes and timestamps it used — so you can go and check it. Things a search box can't do: "what did they say they were worried about?", "has their position changed?", "which episode was that mentioned in?"
