A couple thoughts after using it for a couple years.
1. It actually takes a while to get your head around the fact that the biggest advantage of elixir is having access to the battle tested features in OTP. It takes longer to realize that these benefits don't come for free and elixir might not be the best solution to your problem.
2. The learning curve for writing functional code is different for different people. As a result, it's impossible to figure out before hand how long it will take a team used to writing pythonic code, for example, to start writing functional, elixir code.
3. You're able to emulate something like type checking between pattern matching and ecto schemas but it's not type checking. Be prepared to spend time coming up with best practices for writing tests.
