> Good code doesn’t need documentation

It's amazing how this POV lives on, even in an essay which decries technical debt. Documentation and well-written code fill different roles with only some overlap. Your code can be beautifully written, but if I need to read the whole 500+ lines to figure out what you're doing, rather than read a single paragraph at the top of the file, you've burned through a lot of my time. Good documentation explains the why, code explains the how.
