I think it's already ready for a lot of use cases... though, I think baked in async/await will carry it across the line for many. It's good for low-level duties and even has some decent/good web server frameworks. The webassembly flow is better than a lot of tools as well. I think that there will be some work around nicer UI/UX tooling for graphical apps, but it's still very usable as it is.

I'm learning it now. The async / await stuff is great to have in the core, but isn't something that was otherwise holding me up from learning it.

I believe that after I fully integrate the Zen of Rust, that I will be writing multi-threaded programs with fewer bugs than I would in my alternative languages (C, C++, Go, Python, Lua).

The annoying things in Go that have accumulated in my mind over the last few years are all dealt with in a superior fashion in Rust today.

I'll still be using Go for some stuff at work, but I won't be starting personal projects in it, like I might have in the past.
