TL;DR. Author with “years of experience of shipping to prod” mutates globals without a mutex and is surprised enough to write a blog.

An example where they’re creating a new mutex every time they call a function and then surprised when multiple goroutines that called that function and got entirely different mutexes somehow couldn’t coordinate the locks together.

That isn’t a core misunderstanding of Go, that’s a core misunderstanding of programming.
