Umm, yeah, I've been researching and programming concurrent systems for some time now. CSP is not a good way of doing that.
Go is not very early in its lifecycle. Just look at the feature set - it's the very direct continuation of the work Pike and Thompson were doing on Plan9.
Well... I don't know, I'd consider a language started around the mid nineties pretty early in it's life-cycle. But it's pretty clear to me that which it may be a 'continuation' it's definitely not just 'rebranded'. This is a new project and there's tons of talk all over the place about how "we're working on that". The garbage collector isn't even done yet!
