I'm actually looking forward to Rust having a few more years under its belt so I can do more than experimentation with it (and yes, I've seen the Oxide stuff, and there is plenty we can call stable right now -- I just want it to be a bit more weathered...).
Rust: started 2006, announced 2010, 1.0 2015
The weathering on the two languages seems fairly similar.
In fact it could be argued that Rust is more stable. Golang is talking about a breaking Go2, Rust has a fairly good forward compatibility story and plans.
Rust has no plans for 2.0 either.
Both are stable languages that have been making steady progress.
The second link has Rob Pike state that there probably won’t ever be a Go 2.
