'legit downside of needing to use one language and one framework for all actors' - which is why a lot of Erlang users use it for coordination of messages, and delegate their handling to other services as needed.

That said, most work places I've been at, leadership has -wanted- to use one language. Even with containers and other decoupling technologies. So I don't know how much of a negative effect that downside has.

I've sort of come around in my career to aggressively simplifying the stack where possible... it's handy to be able to script stuff but I don't actually enjoy running a polyglot team. We get a lot more done with one language, one build tool, etc. I tend to save other languages for niche applications (e.g. Lua for nginx scripting).
