Pike's point is that peak PLT is too lofty to be productive or even useful for folks who are actually technically competent and literate relative to the rest of the industry. No one will get anything done if they're spending all their time teasing an advanced type system into inferring the required program.

Mind showing us the source for that?

Go wasn't made for incompetent developers. I'm fairly certain that people who land a job as devs at Google are pretty competent.

Go was made to facilitate rapid onboarding, easy digestion of large codebases, and working efficiently in large teams where people are guaranteed to have widely different educational backgrounds, experiences and ideas about programming.

That's why the language has to be simple, obvious, and be focused on readability. That's also why Go is strongly opinionated.
