After using Rust for about a year on the side, I get the feeling that it's not quite mature enough yet in some places. On the other hand, I also get the feeling that the development of the language itself has been measured and careful which could also be seen as a bit slow.

On the other hand, I hear good things about Go across lots of people I work with although I've yet to sit down and give it a meaningful try. But I also have concerns about the maturity of a language who has jumped to V2 in what seems like a relatively small amount of time.

I'm inclined to believe both languages have lots of promise and could easily be the future of software development, but I'd be hesitant to pick either for a project that needs to be maintainable for a long time in case the language changes too much and leaves you with technical debt.

Where can I download Go v2? Latest is tagged 1.13beta1

Go authors stated multiple times that there are no plans for a Go 2 at the moment. They rather improve the language in small increments breaking as least as possible.

There are plans for Go 2[1], Russ Cox has written blog posts and given talks about design improvements for Go which would go into a Go 2. There isn't a roadmap (yet) but this discussion has been going on for the past year or so[2]. They talk a bit about next steps in the most recent blog post about Go 1.13[3].

They're talking about "Go 2" the brand, not Go 2.0 being a new major version having breaking changes to Go 1.x. There are no plans for a breaking-changes Go 2, only occasional additions to Go 1.x under an ongoing "Go 2" developer relations effort.

There was discussion of a breaking Go 2 in the early days (though it would be opted-into by individual modules -- similar to the Rust edition system but with more significant changes). I think the plan now is to only have minor breaking changes -- the originally-proposed (outright breaking) syntax changes aren't in the current proposals.

But yes, the current Go 2 proposals are much nicer than the originals. But they do still contain some subtle breaking changes (though they have said they'd add vet warnings beforehand so it shouldn't be too bad).
