What if the real threat to humanity isn’t death, but the belief that life needs to mean something?

In this episode of Endgame, Amanda Cassatt and Bryan Johnson explore the architecture of a world where death is optional and meaning might be too. Rejecting first-principles thinking, the problem-solving method rooted in historical patterns and known truths, Bryan proposes zeroth-principles thinking: a framework that imagines human existence beyond inherited assumptions. In this future, meaning may vanish along with our drive for ambition, legacy, and identity.

They discuss why accomplishment might be nothing more than preparation for death, how attachment to power, wealth, and status could undermine our survival, and why it’s easier to imagine the end of the world than the end of capitalism. Bryan also explores a world beyond game theory, where humanity disables evolutionary instincts like competition and status-seeking, treating them as flaws in our biological code.

This is a philosophical autopsy of mortality, meaning, and the psychological machinery we’ve built around being human.
