That is definitely true, but from the article it's the backend that takes time, not the frontend where the language itself resides. If you compile go from llvm, it maybe as long as rust.
The Go compiler being written from scratch based on the Plan9 C compiler is a huge advantage.
I want fast compilation for my dev cycle or for unit tests, I want slow compilation with optimizations, escape analysis, correctness etc. for production (the distinction between a compiler and linter is also not clear, some compiles do what linters do in other languages).
You can get pretty big differences in terms of compile speed / binary size
