> So you need to read a whole book to deploy Elixir

This isn't even remotely true. When I learned Elixir in 2016, I was able to deploy using the exact same setup as I'd used previously for Node and then Rails. This was a Phoenix app, run using mix.

Then the next day, I learned how to compile and run an Erlang release. This made deployment simpler than anything else I'd worked with previously, though not quite as easy as I've since experienced that compile down to a native binary with no external requirements at all.

Now, Phoenix even has a flag to build a docker container with a single mix command. It's not quite as easy to deploy as Go or Rust, but it's truly hard to imagine an interpreted language getting much easier.
