My hypothesis

It's not going to disappear, but I think it's going to fade into obscurity. It's already happened in England. Seriously, anyone who's always lived in a religion-heavy country, come visit England. You'll find it hilarious and a blessed relief.

Vague "some sort of god" belief will no doubt perpetuate among non-criticial thinkers, but the attached obviously man-made religious stories will become less and less accepted. That's my prediction for the West.
