I have mixed feelings about using Elixir (or Erlang); as far as I understand the platform, it is about building fault tolerant systems/high availability, specially in the presence of hardware failure. I think those are handled well by cloud service providers; they didn't exist during the 80s.

I think performance is better compared to Ruby and Python, but then again my experience with web applications is that the domains are best modeled using classes.

For writing networking code and protocols, the binary pattern matching is amazing, though. The Plug libraries are a pleasure to use also.
