Go is not always elegant, it's not always the right tool, and sometimes frustrating - but it's incredibly good at enabling better productivity than the alternatives in this niche. Sample size of one, this is my opinion, and other disclaimers apply.
The middle of the road options I find are worse for anything.
Unless you want to hire big teams. Java, C#, Go are great for that.
But I find with more complex type systems and more expressive languages (which applies to both Haskell and Rust) I spend too much time thinking of which way in going to code something, what abstractions I'm going to use. Then I spend too long trying to make the compiler happy for decreasing marginal returns in reducing bugs. Then the compiler takes too long every time I want to run it. On top of all that, the tools are subpar. I like Rust, I find it so well thought out and elegant, but I still reach for Go to get things done.
All of that makes me considerably less productive. In Go I just use loops, slices, structs, and interfaces. There is usually only one obvious way to do it. It compiles right away, and I get on with my life.
It's not as pretty to look at, probably more lines of code, but it takes so much less time.
On larger teams having simple, consistently styled code is an understated advantage for code review and understanding the system (which together are probably 3/4 of the job.)
In my view, Rust has a good chance of gradually replacing C++, because C++ devs don't shy away from using a large, complex language, and they can appreciate what the borrow checker does for them.
For short scripts I use Python.
Everything else I use Go.
Note that type errors in typescript are actually just warnings and you can ignore them. I never do, but you can.
I wasn't aware that typescript type errors were only warnings. Every webpack/typescript project I've used must have had the typecheck set to error, leading me to believe typescript was some draconian type checker akin to Rust or Haskell.
Racket for general programming (It really is the best for people learning to program and also great for making fun programs that is super easy to install on multiple of computers)
R for statistics especially since I found the functional backbone of the language.
Go for backend work.
