Could anyone more knowledgable explain whether or not my feeling is correct that Elixir becoming (relatively) popular is making Erlang a less viable choice? Whereas the total number of libraries may be increasing, code that might have been written in Erlang is now written in Elixir and established Erlang codebases (RabbitMQ for one) have started to migrate (parts) to Elixir. Calling Erlang from Elixir is easy, but what about the reverse? It reminds of me of how, at least in the early days, Play Framework (largely Scala) could be used from Java but not without much friction. Should I prefer Erlang as a language for its maturity and fewer constructs, it would be a pity to then miss out on new libraries or frameworks, such as Phoenix, that revolve around Elixir.
