When Go was announced it had a spec, a significantly larger standard library than Rust, two compilers (and a parser in the standard library), and much, much better documentation. While the language had changed until the Go 1 release from a few months ago, it had changed less in two years than Rust changed in a few months. Go also introduced a tool that would automatically rewrite your old code to adapt to the new language changes.
