Sure, Go compiles a lot faster than C++, but unlike Rust, Go doesn't operate at the same level as C++, but at the same level as Java. How much faster does Go compile than Java?
I'm pretty sure the compilation time is less to do with the "level" that it operates. From presentations on the topic, most of the time savings were by making the syntax completely unambiguous. Apparently, in C/C++ and similar, some of the longest parts of the compilation process are lexing/parsing/AST-building, etc
