> 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. If you are just starting out and have to make a choice between elixir and erlang, go with elixir. I can't see any reason to start with erlang instead of elixir. You can use all of the erlang codebase in elixir. As a matter of fact most elixir projects call into erlang as erlang has a huge standard library. Also, elixir has nice macros which makes your code a lot DRYer.
