Bryan Johnson predicts a wave of "end of world parties" as humanity's nervous system copes with existential AI anxiety. Think of it as a mass psychological release valve - when systems face overwhelming uncertainty, they default to ritual behavior. We've seen this pattern before with Y2K, but this time the threat model is fundamentally different: not a bug in legacy code, but the emergence of intelligence that could rewrite the rules entirely. The parties aren't celebration - they're a biological coping mechanism, the same way ancient civilizations threw festivals before eclipses. Except now the eclipse might not pass.
