People are reading this as a slight against single authors, but it is a slight against the belief that anyone deeply understands complex code they wrote even a week ago. It is just a bullshit belief. Yes, you build an intuition about it, but you need to constantly refresh your understanding. That is just how the brain works.

Again, that is just how it is.
