Great post, though as a disclaimer, it mirrors my own biases and thoughts on Elixir. I'm happy for its success, but I too find it a step backward.
On the positive side, I don't think we'd have gotten rebar3 without hex guiding the way.
That being said, I wish hex.pm did a better job at distinguishing between elixir packages and erlang packages. It's always super disappointing when I try and stay pure Erlang to have to sift through Elixir packages for what I am looking for.
It's amazing how far Elixir has come in 10 years. I've always hoped it can become a gateway drug for Erlang. I don't think it will, and I guess that's okay, as it pushes Erlang forward in its own way.
