Lex Fridman reflects on his Ukraine war trip, the generational hate of war, a startup calling, and the meaning of masculinity.

Lex Fridman — AI, robotics and electrical engineering researcher who teaches at MIT and hosts the Lex Fridman Podcast. He inspired Andrew Huberman to start his own podcast.
Recorded for episode 100 of the Huberman Lab Podcast, Lex Fridman returns just days after a trip to wartime Ukraine, where he interviewed hundreds of people in Russian. He describes how war creates generational hate, how humans adapt to violence, and how losing everything makes people value relationships above possessions. The conversation moves through social media psychology, the failures of scientific peer review, controversial podcast guests like Donald Trump and Andrew Tate, and Lex's distrust of big pharma after interviewing the Pfizer CEO. It closes on Lex's deeply personal struggle: the calling to leave his comfortable life and launch a social-robotics AI startup, the neuroscience of motivation, and a recitation of a Robert Frost poem.
