I think the "more cores == faster" benefit is overstated.
Without jit Erlang is so slow that languages without concurrency support will kill it. It's even more overstated when something like Go can mostly scale as well over multiple cores but be x times faster while doing so. Not to mention it's 10 years later and we haven't seen massively parallel architectures take off.
I suspect other languages are going to fold the good parts of Erlang/BEAM into them and limit its long-term adoption.
