Rufus Griscom is a writer, podcaster, and longtime techno-optimist who has spent years interviewing the people building the future — from Bill Gates to Reid Hoffman to the founders of Anthropic.

For most of his career Rufus believed technology would overwhelmingly improve the human condition. But after dozens of conversations with the people closest to frontier AI, his view has shifted. He still believes AI could bring astonishing progress - from eradicating disease to ending repetitive labour - but now assigns a serious probability to catastrophic or authoritarian outcomes in our lifetimes.

We explore what changed his mind, why the AI “race dynamic” terrifies insiders more than outsiders realise, and how to stay sane when the stakes range from utopia to extinction.

About the hosts

Thom and Aidan left boring, stable careers in law and tech to found ⁠⁠FarmKind⁠⁠ , a donation platform that helps people be a part of the solution to factory farming, regardless of their diet. While the podcast isn’t about animal welfare, it’s inspired by their daily experience grappling with a fundamental question: Why do people so rarely change their minds, even when confronted with compelling evidence? This curiosity drives their exploration of intellectual humility and the complex factors that enable (or prevent) meaningful belief change.

Nemo the Mormon is a third-generation believer who grew up devout, orthodox, and deeply committed to the teachings of the Church of Jesus Christ of Latter-day Saints.

But over time, he began to discover uncomfortable truths: financial secrecy, historical cover-ups, and leaders who seemed more like businessmen than prophets. Convinced that honesty and accountability were core Christian values, Nemo became an outspoken internal critic - until last year, when he was excommunicated after appearing in the media to challenge the church’s leadership.

We explore Nemo’s journey from devoted missionary to vocal dissenter, what finally broke his trust in the institution, and how he now thinks about truth, authority, and belief.

Spencer Greenberg is an entrepreneur, mathematician, and social scientist who has dedicated his career to helping people think more clearly and make better decisions.

After years of building tools to improve reasoning from personality tests to structured debate platforms, Spencer realised that the biggest challenge isn’t just giving people good information. It’s getting them to actually use it. Today, his work focuses on making psychological insights and rational thinking tools practical, engaging, and easy for anyone to apply in everyday life.

We explore why Spencer cares so deeply about truth-seeking, what makes people resistant to changing their minds, and how his projects (like Clearer Thinking and GuidedTrack) are helping people question assumptions, explore alternative perspectives, and live more intentionally.
