I mean, technically yes when we go extinct, as it's hard to have religious belief when you're dead; but until then... no, certainly not. Human brains simply rely on heuristics too much for people to shake pseudoscientific thinking that leads to spirituality (even without organized religion).

I'm hopefully at least the number of people not believing in organized religion goes down, though. That's the current trend, even if it's just people answering "none".
