It's different game. Nothing is shared (think: one gc per thread), can run 10M+ threads on one cpu and effectively schedule all of them (it has one-of-a-kind scheduler counting reductions, you cannot cpu lock even if you want), really transparent distributive programming, state of the art introspection: "login" to remote process on different node, see how many messages in the mailbox of some process, hot (= replace running code) code reloading etc. Edit: Essentially: some actor library for language X is not even remotely (if any) erlang. Maybe cloud haskell some day will be there, but its all introspection parts is basically nonexistent right now.
