Maybe it was true 6 years ago, but I'm currently playing with Elixir/Phoenix and I feel very productive, Phoenix is well design and adding new functionalities is not that hard and the code is easy to debug. On the other side, Elixir and Erlang are not that popular and every time I talk about it to other developers, they may have heard of it but can't talk about it, so it's probably not that easy to find devs for a startup. But the barrier to entry is probably what keeps the libraries well designed. For anyone interested in Elixir I would start with those books in this order "Elixir in Action", "Programming Ecto" and "Programming Phoenix Liveview".
