Elixir really needs to lose the perception, if there is one, of it being a subset of the Ruby/Rails community. It's true that the initial influx of Elixir developers came from the Ruby world back when Elixir was new, but that was a long time ago. Tons of Elixir folk come into it nowadays without a Ruby background.

Elixir and Ruby really aren't that similar anyway. The syntax differences are very superficial - Elixir's a functional language with very style and semantics to Ruby, and that's even before you get into the magic of OTP and the BEAM, for which Ruby has nothing comparable.
