It's true that some library coverage is definitely the weak point of Elixir. Authentication in particular is a gaping hole although efforts like `Pow` and `phx.gen.auth` do help to no small extent.

The community is excellent though. You'll rarely find such a welcoming and ready-to-help community as ElixirForum (although the occasional exceptions do happen like everywhere else).

Elixir is not about the syntax or anything. It's about (a) the underlying runtime, (b) the very powerful metaprogramming facilities and (c) Phoenix / Absinthe / a few others.
