- true parallelism (this is why we need guilds in Ruby 3)
- the BEAM
- functional yet OO at a higher level [0]
- all the Erlang/OTP goodies for free
- Phoenix/Ecto are quite nice frameworks and solid alternatives to the server-side JS world
- “looks” like Ruby though is an entirely different beast
Crystal on the other hand looks more like a Rust alternative to implement almost-as-C-fast Ruby gems. I'm sure it can evolve into an ecosystem but since it's quite far from being stable it will take some time, time in which the Elixir ecosystem will grow because its Erlang foundation already fixed the big issues.
