Yeah, we get people saying we're not 'true Erlang' but that was kind of the whole idea. It's an alternative to Erlang and Akka, pulling the best from both. And it's so active and involved that it's almost becoming more of an RVM than a library only.

With `jRuby` and more and more with `Rubinius`, the concept of actor-based concurrency itself is coming into range of being language-unspecific, with Erlang not being the default authority on that.

Akka gets a lot of respect, and of course Elixr, Go, Rust, etc get a lot of concurrency attention... But Celluloid with Ruby is far superior in my opinion, because it is not only performant and functional, it actually allows you to get into the internals and change how your actor system behaves. It's as simple or as complex as you want it to be. Oh and you don't feel like killing yourself while you're writing code.
