>The problem with concurrent computing is not a lack of Erlang awareness or message passing awareness

It most certainly is.

We have been so thoroughly fed/brainwashed with Shared-Memory concurrency that most people don't even think beyond it unless forced by circumstances (or from curiosity). That is where Message Oriented Concurrency languages like Erlang can help. Just reading Joe Armstrong's thesis Making reliable distributed systems in the presence of software errors will teach one a simple approach to robust Concurrency that works and can be emulated in another language if you don't want to learn Erlang (the difficulty may vary based on language support).

PS: Folks may find Foundations of Multithreaded, Parallel, and Distributed Programming by Gregory Andrews a good reference for most major forms of Concurrency.
