If you invest time learning Erlang everything around Elixir will make sense and it will be a pleasant experience not only to "write" but to test, debug and maintain as well. I would go through this slightly dated but gentle introduction before learning Elixir: https://learnyousomeerlang.com/content

Thinking in processes and knowing/using the GenServer abstraction is the core of Elixir programming.

So, one negative is that difficult to use without Erlang knowledge. Also some good libraries are Erlang only for compatibility/historical reasons.

this. I had piloted a project in Elixir a few years ago. It wasn't until I really learned Erlang that it became a pleasant experience. In the end it was replaced by another team in another language.

But this seems like a big issue to me. It probably makes the learning curve high if u basically need to learn 2 languages.
