I think Elixir is quick to learn, long to master. You start off building web apps in Phoenix, being relatively productive from the start, and thinking to yourself "well, there's definitely some magic I don't understand, but this feels a lot like Ruby." You'll immediately notice and learn the smaller differences (immutability and pattern matching).

Then one day, you'll need to store and mutate data in process. And then you'll learn about GenServers and Supervisors.

Then one day, you'll want to have some base functionality but for whatever reason, composition isn't a good fit, so you'll start to dig into macros.

Fundamentally, Go is much more Ruby-like than Elixir (Ruby and Go have shared heap, global GC, array-based data structures, same evaluation strategy, mutability, ...). Elixir is very different. But it's discoverable.
