It's conceptually much simpler. Erlang(/Elixir) does not have separate concepts of routines and channels, you just send messages directly to a process (and it does whatever it wants with that), and not only does it embrace "don't communicate by sharing memory, share memory by communicating" it enforces it: Erlang's data types are mostly immutable and each process has its own private heap.

The language does look and feel somewhat odd though, it was inspired by prolog (so will look very odd if you've not used prolog) but doesn't do full unification (so will feel very odd if you've used prolog).
