Bruce argues for the secularization thesis: less and less people believe in God, and those that do are more and more tepid in their belief. Fundamentalism is a rearguard action, sparked by the increasing indifference that religion encounters.

He has the figures that back up his story and makes it quite convincingly. For my part I'd be happy to see the monotheisms fizzle out - which in many ways they do seem to be doing, slipping back into syncretic "spiritualities" that might, hopefully, reduce humanity to its rightful place among other forms of life.
