Bootstrapping is a useful test of the completeness of a compiler, and it makes development easier. The Go compiler is fast because it does very little. It doesn't do much optimisation and Go is not a very sophisticated language and so does not require much of it's compiler. It is not comparable to the Scala or Dotty compilers.
