I am astounded by the abundance of languages on the Beam, Gleam, LFE, Purerl, Lua and possibly many more.

Have you seen Lumen, a Beam implementation in Rust that targets Wasm?

https://github.com/lumen/lumen

I had heard of it but never tried to use it.

I hope at least some of those languages get enough adoption to become viable production choices. I feel, apart from Elixir, Gleam has the most “popularity potential” right now.

The nice thing is that they all speak Erlang terms so you can mix and match them. Beam is such a wonderful VM!
