This is not the fault of Elixir. It’s the fault of trigger happy CTO’s who chase shiny new objects without thinking about the long term, big picture. I’ve made plenty of unsexy decisions when my heart was pulling me in a different direction - because it’s the right thing to do based on the team you have or the direction you’re headed.
Adopting Elixir, like Clojure or Haskell or any of the more esoteric languages is a commitment. Don’t do it if the benefits aren’t there or you aren’t willing to make the investment.
