If we're being serious here, I'm pretty sure Go is specifically for very very large orgs and almost no-one else. Go optimises for low GC pause time, fast compile times and in-your-face concurrency at the expense of almost everything else. The fact that CSP is formalised and well studied, and the lang itself is sufficiently C-like and stripped down makes it amenable to large scale static analysis as well.

If you need relatively high performance but can tolerate it not being 100% in exchange for nice things like GC, use Go. Where does Java fit in?
