Your point about Go shining a lot more brightly when working with a team which has mixed skill levels was one of the design goals of Go, so it seems they’ve succeeded on that front if you’ve come to that conclusion independently!
IMO, Go is the easiest language to read by far. Python can be, but lets one use a lot of hard to figure out magic. Go is very much WYSIWYG, and to me that's its greatest strength. It's easy for anyone to jump in about anywhere. And that lends itself well to teamwork.
I find that's only true so long as the problem you're solving fits well into Go's view of the world.
If you want to make a data structure holding the equivalent of a parametric enum (or tagged union from C), go is very awkward to use compared with richer languages like Swift or Rust. Go is also awkward if you want to implement custom generic data structures.
Eg, this[1] code I wrote a couple years ago for doing text based operational transform became about 1.5x longer in Go compared to rust or typescript because its so awkward to express a parametric enum in go. And it was much harder to read & more buggy as a result. Sadly I lost the go version of the code. I'd be curious if someone with more go experience could do a better job, but I'm skeptical.
Hopefully the situation improves somewhat when generics land.
