We're using Elixir for the back-end of our web application, and so far I'm very happy with it. Probably the biggest issue we have with Elixir right now is libraries, but it's a more subtle problem than "there isn't a library that for this thing I want to do". To the contrary, I've been pleasantly surprised at how many libraries are available and how good they are. The issue with libraries that I see is that because the language is so young and the core libraries are changing so rapidly (for the better!) a lot of useful third-party libraries have trouble keeping up. So we frequently find that a new feature has been rolled out to a core library that we really want to use, but upgrading it breaks a dependency in a third-party library. It's sort of to be expected, right? The language has captured enough mindshare that people are building useful libraries left and right, but it hasn't gained quite enough adoption that there are armies of developers who can devote time to keeping those libraries updated to the minute - you don't have 100 developers behind a given library, you have 10 or 2 or 1.
