It really depends on what you mean by general purpose.

At work we use Elixir for web and data ingestion, and I could have used Ruby for web but Ruby is considerably behind for data stuff.

Elixir is fine for one-off scripts, Ruby and Python may be a bit more convenient, but overall they are all too heavy to distribute compared to languages like Go and Rust.

Elixir is also used for high-end embedded and there is the whole distributed programming bits, which is quite specific to its platform, and more complicated to setup in almost all other places.

So overall it does provide some nice coverage across a couple areas although it lacks on other ones (GUIs, ML, etc).
