The phenomenon you're talking about, imo, doesn't have anything to do with Erlang or Elixir.

All languages have limits to what you can do natively. There will always be some tasks where you will cross a language barrier from "your" language to another. To me, the question is: "Is the area that Elixir covers big enough to recommend?" and I think the answer is yes.

I do not think most programmers need to learn Erlang to use Elixir - but I think programmers will often encounter Erlang and can decide to learn it (or look for a different library that's pure Elixir). I am sure that there are individual programmers who would learn pure Elixir, but get 'scared away' by Erlang...but I doubt they are hurting the language ecosystem in a meaningful way. Focusing on this would both be optimizing something that does not, in general, matter - and would be trying to achieve an impossible goal.
