Sure, my opponent's 2090 commuter might stop at a shrine, but stopping isn't belonging. Quasi-religious habits and meaning-making don't rescue institutional religion; they're often what replaces it. And yes, high-fertility regions give religion a demographic tailwind, but that wind fades as education, urbanization, and female empowerment spread, the same forces that hollowed out pews in the UK. Adaptation proves religion is flexible, not immortal. A reshuffle can still be a long goodbye. By 2100, religion may persist as niche ritual and identity, but not as the default public force it was. That's disappearance in the sense that matters.
