There's going to be at least one identifiable group that is the "cutting edge", and they are going to have certain characteristics or tastes or whatever that will tend to separate them from the not-cutting-edge folk.

The problem is that there's no evidence at all that it's language which is the characteristic function. Looking at most of the devs that I truly respect and admire, few if any, are the ones that spend a lot of time with cutting edge languages. And most people I know who are famous devs that use cutting edge languages, are famous for using, writing about, or developing cutting edge langauges.
