And in what aspect is Go a better than the million other language with GC? Like, it is C level bad at expressivity, way too verbose because hardly any abstraction can be made there. Concurrency is the only thing going for it.

But how is it any better than Java or C#?

And Rust is a low level language, so it has to get away with rare cases where a GC is not applicable. And being low level of course imposes the memory layout of the program on APIs as well, but that is a known trade off when one goes low level.
