Any language that helps to reduce C's status quo is welcomed, Go, Checked C or whatever.
One piece at a time.
Yeah. Fyne picked Go because it is a great language for building a GUI - not because we were Go developers.
Fyne existed before the founders knew any Go :)
Mostly coding window managers and desktop environment in C/C++ is so painful that you can see why it stagnated 20 years ago...
Is that really a problem with C/C++ or an issue with the X Window System?
Personally I think both. Yes the X11 APIs are horrible to work with - but decent code can abstract that away so the app APIs are sane. Doing that was easy with Go, but doing the same with C seems to end up passing around `void*` everywhere, so type safety (and a good coding experience) goes out the window.
