Elixir/Erlang works very well in a semi-embedded environment where you need a higher level command and control component that behaves in a deterministic way and is pretty robust.

I was involved, years ago, in using Erlang on these devices: https://www.icare-world.com/us/product/icare-eidon/

It was a lot of fun and there were some very interesting challenges for everyone involved.
