I learned Go on and off in recent years on the side(daily job does not need Go), I like its battery included stdlib and cross platform support.

I do feel its binary size is large comparing to c and c++, and multiple Go executable can not share libraries as easily as how c/c++ uses the shared lib, when I have a few Go binaries they add up, and I do storage constrained embedded development a lot.

On the desktop side, I really hope Go can have a GUI in its stdlib, something like what Flutter/Dart does: adding a Skia kind of engine and let me do GUI cross platform, that will make Go main stream like wild fire.
