The same goes for code comments though people are much more vocal about their disdain. It's ironic given how frequent AI is used to generate docs. But docs are much better written by the person who wrote the code, the person who has all the context.

These things never take much time but people dismiss them because of that. Because each commit and each comment in isolation isn't very valuable but they are very helpful in aggregate. I'm not sure why this bias exists though, since the same is true for lines of code. It's also true about a ton of things. All the little things add up. Just because it's little now doesn't mean it's not important
