Additional quotes by Joe Armstrong

I thought if you multiply two integers together, you get an integer. But apparently you don't in PHP. You get a floating point number, which gets bigger and bigger and that's okay. Until you get to factorial(171), and then you get "INF". I don't know what "INF" is. I think it's infinity actually. But in that case, it's probably wrong, because infinity is awfully big. Bigger than factorial(171).

In Erlang, F(G(X)) is used for small steps. Pipes are used for big steps. The big steps semantics is processes. It's messages between processes. Processes are used for big computation. When you got F(G(X)) is a small step, and we map small steps on the same core. We map big steps on processes. Processes map on multi-core. The system just does it for you.
