Religion is one of those things that dates back to the earliest beginnings of humanity and has been a component of every civilization we've ever discovered. I don't think it's going anywhere any time soon. Nor should it, by the way. What is happening, however, is people are slowly advancing to the point that religious tribalism isn't as significant. Religious extremism and violence are far less prevalent. The next generation will probably see the last dying gasps of that movement before it becomes mostly relegated to history.
