Yes, the issue isn't that most comments are inaccurate, it's that the inaccurate ones are so costly. When the comment doesn't match the code, it makes you question the code and the intent. 90% of the time, comments are accurate or just redundant (the code is descriptive enough), but that 10% of the time when the comments says A and B is happening, I end up chasing down whoever or digging through changelogs and tickets to find the comment wasn't updated.
