One big advantage that Go currently has over Rust is much greater stability, in terms of language and standard library changes.

This means that Go is far more predictable than Rust currently is for anyone who wants to use it seriously, especially for larger systems that will take some time to develop.

There has been talk that Rust 1.0 will be released later this year. Hopefully that is the case, as it'll allow for the stability that'll then allow more users to seriously consider using it. But until that happens, Go is a much more viable choice in many cases.
