The Great AI Safety Debrief with Dr. Petr Lebedev - Part One (460)

Sat Feb 07 2026

Listen

Intelligence is emerging from sand and less than 1% of the population seems to care! Physicist and science communicator Petr Lebedev joins the podcast following his SXSW talk to explore why AI is advancing so fast, and why that should make us pause. From completing a PhD in physics and writing for Veritasium to leading science communication at Palisade Research, Petr steps in to bring some clarity to the weird, wild, and worrying sides of AI. Did you know that no one truly understands how large language models actually work? We go deep on misaligned systems, humanoid and dog robots, and why many experts believe AI could pose a serious global risk. Is AI our greatest tool — or something we're slowly losing control of? This conversation is big, so we've split it into three parts. Part two drops next week.
