My biggest hurdle was being too impatient to learn how to code with immutable data. I banged my head on the desk for two days to get through what I felt was a trivial problem (something with updating files in S3), which I eventually rewrote in python in less than an hour. Immutability (and the resulting maintainability and predictability) is really appealing to me, though. When I try it again, I think I'll focus on educating myself around the language upfront and not just learning as I go. Everything else about the language, Phoenix, and the tooling was really nice. For the same reasons as others have said, I would not pick Elixir for a business, though.
