It doesn't. I think goroutines make concurrency easier that it is in, say, Java, but Go still passes around state and that is where a lot of the issues with concurrency arise. Concurrency is much easier to deal with in functional languages, where data is transformed via chains of functions, rather than stored in state.

The difference is that in Go, it is unidiomatic to share mutable state across threads, while in C/C++/Java it's not.
