Yes, atheism will defeat religion in numbers. Believe it or not.Atheism to Defeat Religion by 2038?
I don't think so.
I believe there will always be people who believe in God, and people wanteing to stay part of a religious structure. Their number may decrease, but spirituality and beliefs are there to stay. Atheism doesn't bring an answer to many questions individuals may have, it seems.
That being said the thread here does not imply in any way that all religious superstition will be wiped off the face of the earth completely. There will always be the self deluded few who need a crutch to deal with reality.
