Go to Elixir if you actually want to learn more, expand your mind, and are tired of bugs that can only occur in a mutable OOP language. And if you want to take advantage of the extra guarantees provided by a functional language, such as functional immutable datastructures making concurrency idiotproof.
There isn't much that is "mind-expanding" about Elixir coming from Ruby or really any other interesting, dynamically-typed language that I know. It's fine but it's nothing special; BEAM is a better argument for it than Elixir itself.
