I think Erlang's concurrency model is quite a bit different to the likes of Go (and probably most other languages). With Go you still have to worry about shared memory and have to manage that correctly when using Go routines. In Erlang, there is no shared memory with processes. Parallel processes are completely independent, they have their own stack and heap, and so the only way one process is able to share or access data to/from another process is through message passing.
