You're totally right about CGo. For example, I'm very happy that I can use the insanely well-tested original SQLite C library directly in Go, and sleep easy that it's not some half-ported pure Go library.

(I know there's an auto-transpiled SQLite lib as well, which is probably just as good. But then I have to rely on no bugs in the transpilation process, and I don't like that. That may be superstition though. ;) )
