I think you’re right! However, where is the Big Data revolution with Erlang/Elixir? It looks like the Erlang User Conference 2013 had a Big Data track where Erlang is considered to be the next big thing. (Each of those has a YouTube video, if you search the talk’s title.)
It must just be a matter of Java being more popular than Erlang, despite Erlang/OTP being more well-suited for the task. I guess it is up to us now to bring Elixir to the arena!
