  • Is AI Outsmarting Us? Part Two of the Great AI Safety Debrief with Dr. Petr Lebedev (461)
    Feb 14 2026

    In part two, Dr. Petr Lebedev and I dive deeper into how modern AI systems are grown, not programmed, and the emergence of Shutdown Resistance. We explore AI performance in math and coding competitions, the rapid evolution of ChatGPT models, and why companies are already letting AI write the majority of their code. Petr explains how huge investments globally are pushing these systems forward faster than we can fully understand or control.

    The final episode in this 3 part series drops next week!

  • The Great AI Safety Debrief with Dr. Petr Lebedev - Part One (460)
    Feb 7 2026

    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.

  • The Milky Way's Mysterious Glow with Prof. Geraint Lewis (459)
    Jan 31 2026

    A mysterious glow from the centre of the Milky Way has scientists intrigued. Astrophysicist Geraint Lewis explains how this gamma-ray excess, first detected in 2009, could be evidence of dark matter particles interacting deep in our galaxy. With dark matter believed to make up a vast, invisible halo that holds galaxies together, uncovering the source of this glow may bring us closer to understanding what the universe is really made of.
