It should also be noted that both are young languages and they are evolving rapidly. Erlang itself is nearly 30 years old, but it wasn't open sourced until 1998. OTP came shortly after. Erlang doesn't evolve rapidly at all (at least, not in the typical sense of "Software innovates so quickly - Last year I was using one event loop, and this year another"!). It's remarkably conservative, yet still ahead of the pack. That's what makes it so great.
