Golang is good only insomuch as C is good, because it's clearly inspired by C. That's why golang is popular, because it's very similar to something everyone already knows. The switching cost is low and the tooling is really nice. Some things are nicer than in other C-like languages, some things aren't. The bottom line is that language innovation these days is largely not happening in C-like languages, so most language innovations aren't popular. Languages like Swift subvert this rule, however Swift has its own (arguably more influential) corporate backing.
Go isn't bad, it's easy. Very easy. Easier than almost everything else. That's why it's popular.
