Which is why you're reviewing changes. I haven't memorized what every line of code does, if it was worth commenting then it was confusing-enough that it needed the comment and so I'll read the comment to make sense of the code being changed. If I don't read the comment that means the comment was too far from the confusing code.

Alternately, you can say the same about informative variable names or informative function names. "If I change the function then the name is no longer accurate". You don't say that because function names and variable names are short and clear and are close to the problem at hand. Do the same with comments.

Which is why the copilot hyper-verbosity is harmful. Comments need to be terse so your eyes don't filter them out as noise.

But copilot code review agent is pretty good at catching when code and comments diverge (even in unrelated documentation files).
