What date do you estimate atheism will overtake theism in the world population

[Coveny]

I think it's quite premature to declare victory, but ultimate victory is not out of the question.

How long it takes, how it comes about, and how many fits and starts are involved, are all huge unknowns. And there are scenarios where religion wins big-time -- at least for awhile.

It's just hard to accept that dealing in reality is not ultimately a survival advantage. Dealing in reality has got us technology, longer life spans, greater comfort and self determination and the well-being that goes with it, already. Sure, some will cut off their nose to spite their face, but in theory at least they should tend to live shorter, meaner lives.

Then again, all evolution cares about is survival, not enjoyment.

Time will tell.

So in the scenarios where atheism wins what would you say the average time that atheism becomes the majority is?
