Adam Frank, astrophysicist and astrobiologist who studies planetary evolution and technosignatures. He discusses searches for extraterrestrial technosignatures versus UFO reports. They explore the Silurian hypothesis about ancient industrial traces in rocks. Conversations cover limits of interstellar travel, why anti-gravity claims fail, AI risks as powerful autocomplete, and the Moon’s role in Earth’s history.

Episode notes
Humans Could Rapidly Diverge From Present Form
- Human form could change rapidly under genetic engineering and cultural selection; in 1,000–100,000 years future humans may lack arms or conventional bodies.
- Frank highlights our ability to 'take over' evolution via biotechnology and long-term trajectories are unpredictable.
Why Today's AI Hallucinates And Can't Be Trusted For High Stakes
- Current large language model AI is essentially statistical autocomplete, lacks true understanding, and will continue to hallucinate (make up facts).
- Frank warns against embedding these flawed models into critical systems because their errors are unavoidable and untrustworthy.
Force Human Work To Avoid AI Shortcuts
- To counter misuse of AI, design tasks that force humans to produce work without AI assistance (e.g., in-class handwritten writing) and limit blind reliance on generated outputs.
- Frank's colleagues require in-person or offline exercises to prevent AI shortcuts in student assessments.
