@ xcalibur:
I agree that total elimination is not likely, so long as we assume natural born humans. Religion is extremely sticky a concept; once created it's very difficult for it to go extinct. However, you misunderstood me when I said that the propensity toward faith is built into the human condition. Faith, yes. Religion, no. Religion is an invention, far more malleable than the faith impulse underpinning it, and has already eliminated previous versions of itself many times as a part of the social evolution.
That's important. It gives us with an opening to eventually correct this tremendous mistake without resorting to the same tools of oppression and conquest which religion itself uses to spread and endure. Through education, we may make people more scientifically literate, more critical, and more disposed toward philosophical fulfillment. Religion provides various benefits that are available more purely elsewhere in life. It also lays a heavy hand on the mores of society, which can easily build resentment toward it (among those who cannot escape the hand) or apathy toward it (among those who can). Meanwhile, through continued prosperity, we can give people the kind of lifestyles which naturally lead away from religion.
Religion has already imploded over the last century. Life as we know it would not be possible otherwise. Today, secular societies dominate many corners of the Earth, and many segments of people within societies are secular. In short, I think you give too much credit to religion's staying power. Its strongest roots lie in the ignorant, the downtrodden, and the indoctrinated. All of those conditions are correctable.
