The great thing with Elixir in your toolbox is that you're prepared to write the quick mostly-static app or the full multi-server connection-processing behemoth.

I just type "mix phoenix.new <project name>" and I have a relatively light starter framework that's ready to go as far as I need to take it.

Rails had the same "ready to go" feel as Phoenix, but I learned from painful personal experience that you hit the scaling wall way too quickly - but with that project I never realized that scaling would ever be a problem. How was I supposed to know which sized framework/language to use from the beginning.

So sure, the use cases where OTP will really shine for you are potentially narrow. But Elixir is actually quite fun to work with even for small projects and it's fantastic knowing that if a project grows unexpectedly, I don't have to scrap it and write it in something else.
