It's great that they support C and JVM stack. But for other major platforms such as NodeJS, Go, ... we still need to approach the goal with some C extensions integrated in both platforms. Erlang/OTP distribution/clustering is really not designed for heterogeneous environment which is fine, since it is used in telecom industry with nice commercial support contracts backed by Ericsson. However I don't consider it as an amazing piece of engineering from a perspective of a system designer who is dealing with many teams with different language/stack preferences.

Erlang is what you would use to implement a single service (which may run on a cluster of multiple nodes). It's not a generic messaging layer to use between services, you can use RabbitMQ or ZeroMQ or whatever you like for that.
