If each generation is measurably less religious than the last, why would that trend reverse before 2100? Secularization isn't random: it tracks rising existential security, education, and urbanization, which weaken religion's explanatory and institutional monopoly. Generational replacement compounds it, because people raised outside regular practice rarely drift back. The other side may point to pockets of growth or religion-as-identity, but that is retention, not revival. A world where religion is a minority habit rather than a default framework is disappearance in the meaningful sense.

The other side's language analogy actually cuts against them. Languages adapt and migrate, yet most cease being living defaults while leaving words and rituals behind. That is exactly what disappearance means here: religion persisting as heritage and identity, not as the operating framework for most societies. Their adaptation point describes retention, not reversal. Growth where life is hardest fits secularization theory rather than refuting it, because existential insecurity is the variable. As security, education, and urbanization spread this century, generational replacement keeps compounding. My opponent is arguing transformation, which is compatible with my claim. A minority habit by 2100 is disappearance in the meaningful sense.

Is a residual candle really the same thing as a living religion? My opponent's grieving commuter actually illustrates my point: a private ritual fragment is what remains after religion stops being a default framework. If by 2100 religion mostly survives as identity, ceremony, and occasional comfort, it has disappeared as the operating system of most societies, even if fragments persist. The other side calls that transformation, but transformation into a minority habit is still disappearance in the meaningful sense. Uncertainty about the exact path does not make the century-long trend reverse, and generational replacement keeps compounding it.
