Oct 30, 2026 · 26m

Summary

This episode explores the Fermi paradox by proposing that the formation of the first eukaryotic cell may be the "Great Filter" preventing the rise of alien civilizations. The discussion highlights how a unique endosymbiotic event solved critical energetic and computational bottlenecks in prokaryotic evolution, allowing for complex life to emerge just before Earth became uninhabitable.
