I disagree about it being God-less per-se. I think people will come back around to a conception of God, not as an anthropomorphized magic sky wizard full of wrath and dogma, but as a philosophical concept that seems to underpin all of reality. And when that happens, they will look back at the religions of the past and find that they, in their own words, often spoke the same wisdom that will then be commonplace. We merely misunderstood it because we lacked the context see what what was really meant. Because the thing about context is that it is necessary for communication, and you don't get it for free.
