We've been able to hire and leverage our existing Ruby developers to support our Elixir apps with success. It usually takes a couple of weeks of getting aquatinted when starting from scratch, but after that, execution increases linearly until it levels off at the developers' baseline.

If you're OK with questions:

One of the things that worries me about suggesting Elixir at the Rails shop that I work in is the concern that we'd have to develop a working knowledge of Erlang as well as Elixir. Can you speak to that?

The VM they both run on is the same - so you'd have to know some basics about that regardless. You'll also have to learn how to read Erlang syntax since there are many 3rd party Erlang libraries you can use from Elixir. The syntax is slightly different from Elixir, but the mental models are pretty much the same, so it's really not that difficult to get a working knowledge of reading Erlang.

Thank you, that was very clear and helpful.
