Does anyone think we will live in a post-religious society?
Not in my lifetime; I am 71. Religious tenants will be hard for many to leave (as they were for me). I believe it will take several generations.
Not for hundreds, possibly thousands, of years.
Yes, but not in my lifetime. Need at least two to three generations to die off before we are the narrow majority. And a few more than that before it's nearly universal. But that is rapid change, I think.
