Learning languages and using them to develop an actual production-grade product are two different things.
Pick something proven.
I worked in a Scala shop and people spent tons of time flailing about arguing over syntax, dealing with bad IDE plugins / slow tools, etc. They'd have been better off just sticking with Java.
Elixir and Erlang have similar symantics, compiles to same byte code. You can use any Erlang library in Elixir without any overhead, all the tools (debugging, profiling) which works with Erlang works with Elixir.I don't see why you can use Erlang and not Elixir.
