Not a single person has spoken up to say that they write a lot of tests AND they have a lot of bugs.

All the negativity (downvotes) has come from people who are trying to argue that writing tests doesn't solve the problem of bugs. The same people who don't write a lot of tests AND have a lot of bugs. ¯\_(ツ)_/¯

I write a lot of tests and I don't have bugs. I have decades of experience and millions of lines of code, with this simple fact. I know it is true, at least for me.

I don't know what else to bike shed here other than the constant downvoting by people who somehow don't believe my claim. The loss in karma doesn't bother me, I know I'm right on this and it appears as though the only people who disagree with me are the same people who don't write tests (and have a lot of bugs).

golang is a relatively simple language. It is why I like it so much. Occasionally there are somewhat difficult things to reason about, but if you write golang code that is easily testable (and this requires thought and planning), then my experience is that even the "harder" channel/goroutine code can always be tested in one way or another.
