To me the real amazing thing about Erlang is more the fact that these patterns based on queues and messages and supervisors scale so well. They are easy to implement on a small, single node application. You can compose them. You don't need to complete reauthor your calls to start distributing them and fanning out responsibility across your nodes because you've been doing RPCs from the start. A multi-node application is not that much more difficult to reasonable than a single-node application
