Exactly, and though Ruby has an FFI (Foreign Function Interface) similar libraries were not created and Ruby was pigeon holed as a language you build CRUD apps in.

There is a dev adding Ruby bindings via FFI to ML libs. Unfortunately it doesn't seem to be a large community (yet).

I don't do any ML and don't know much about it, but the Elixir / Phoenix people around José Valim now build ML software (nx, livebook) and I'm excited for this.
