Your point still stands but, since the field has so many terminologies that are conflated, I wanted to let you know that "active objects" is a specific kind of actor model and Erlang is not an instance of that model. Active Objects is essentially Java but with asynchronous calls, much like using gen_server for everything.

A good paper that untangles the terminology is "43 years of actors: a taxonomy of actor models and their key properties".
