It's not yet an enterprise language; along the languages/frameworks, there's a huge ecosystem of QA, monitoring, security, etc solutions in the Java/.NET space that just isn't there in Go. I mean there's a slow shift, I keep hearing of "rewriting a Java codebase to Go", but it'll be a slow process. And especially the bigger projects that represent 30 years of Java development will and should be reluctant to start rewriting things.
