I don't think your description of Elixir and Phoenix is correct:
Elixir is a language targeting the erlang virtual-machine. it does not seem clojure-inspired. Phoenix is a web development framework written in Elixir.

I was like, okay, I’m going to call them protocols because the closest thing we have today to what I want is Clojure
And he goes on talking about more inspiration and similarities from Clojure like Agents, etc.
Edit: Ah I see where you could have gotten confused. By "version of Clojure" I meant in that it is very similar and has taken a lot of inspiration from it. Elixir isn't an actual dialect of Clojure the way that ClojureScript and Clojerl are. That's not what I meant to imply. Having used both language, they do share a lot of similarity in design, with most of the differences being Beam/Erlang vs Jvm/Java, and Elixir pulling more from Ruby, while Clojure pulls more from Lisp. This is what I meant by "a version", I should have said "is like Clojure, but..." instead I think to avoid this confusion, but too late for me to edit now.
