It's not that my comments are infallible, but if I write something wrong/silly it'll be caught during code review. similarly if there's a comment missing before some arcane nonsense nobody will remember in 3 years, then i'd expect a PR reviewer to tell the dev to add one.

Copilot just likes to puke very useless comments whenever I type "//", especially in autocomplete mode (I don't really use the chat mode).
