As someone pretty plugged-in to the Elixir community, I can fully endorse it. There are a lot of really exciting new developments happening on the regular, but it also has really solid foundation, being built on the BEAM (Erlang's VM).
As a language, the syntax is pragmatic and approachable like Ruby, but the VM scales super well since it's Actor model provides concurrency by default.
There are even projects working to enable GPU-accelerated numerical computations (Elixir Nx) and Jupiter Notebook style collaboration and code sharing.
If you're primary goal is to learn something fun that's also great for getting actual work done, you'll probably really like Elixir.
My recommended introduction would be installing it, and running through their official guide from the top:
