So, you're right, of course, that the language differences are major, however, I don't think it's unfair to say that Rust's instability is a source of concern if you're planning a long-running project. No one wants to get stuck on a pre-1.0 release for their production system. Go is post 1.0, and has a backwards compatible guarantee, which means the code you wrote last year under 1.0 is guaranteed to compile today under 1.3. That's pretty important. It's not an indictment of Rust... it's just a fact of the place in development where it exists right now. Go was in that place before it hit 1.0, too.
