I didn't imply otherwise, nor is the story different on the Erlang-Prolog axis (actually it's even more pronounced there.) I literally called it "set dressing". Where I think you go off the rails is that you're conflating surface-level things with irrelevance. Which isn't really true, especially in matters of taste.

I find this to be a very strange thing to get defensive about. It's not exactly a subtle part of Elixir's history. It was pretty well documented to be born out of the creator's dissatisfaction with concurrency in Ruby, and simultaneously, for a more Ruby-like language on the BEAM. That doesn't mean it's literally Ruby-on-the-BEAM (which was originally attempted, and didn't work out), however mistaking that as cause to dismiss the link between the two and the carry-over appeal for developers is an unsound overcorrection.
