Just as long as it happens is all I care about. It's a process, like anything else it just takes successive generations of breeding the ignorance out of our genes. I think there will always be some kind of religious insitutions around, people seem to need to believe in things that are fantastic and supernatural.
They couldn't even escape the pull of it in "Dune," there was plenty of religion even in a place where it seems to have no great purpose. People are just that way - they are willing to put their belief in crazy stuff.
