I think the problem with less Erlang adoption is that Elixir has a connection with more modern languages and a more forward-looking community (at least in my experience). I wrote Elixir for 4 years until I got my current job, and I never really felt the need to write pure Erlang, so I never learned more than I needed to simply read Erlang code. Haskell offers something unique in that is a much more academically-modeled functional language. Personally, I like the OTP model better, which then lets you take your pick of a BEAM-compatible language.
