The Go language was actually created while waiting for C++ to compile. Their goal was to create something that was better than C++ for network services and they succeeded- but that's a pretty low bar! Most companies that don't have major performance concerns don't use C++ for networked services. If Rust was already mature it would have been a good option- except for the compile times which was one of their main original issues could well be worse in a Rust code base! I have seen this myself- Go being used instead of Rust with the biggest reason being it compiles so much more quickly.
