> Correctness is not something that matters in the real world. Even defects don't really matter. What matters is problems that defects cause. It's a subtle difference, but very important one.

To me, saying ”correctness doesn’t matter” is equivalent to saying “it doesn’t matter whether your app does what you want it to do”, which makes no sense to me.
