You're not going to have a TON of jobs available where you can use Elixir - but if you want to learn Elixir to learn other valuable skills like concurrency and parallelism or just expanding your mindset by using a functional language - then that's obviously more useful than... not learning those things? Architecturally, the BEAM - to me - is super interesting and enlightening. So learning more about that - I think - is great for distributed systems and fault tolerance. Also - Erlang is a really cool language, too, I think. In many ways, it's obviously more valuable to learn something more practical like C or Java. But in other ways, I spent a decent amount of time playing around with Elixir, and indirectly, it was one of the most valuable things I've done in my career, I think.
