Some comments are far worse than no comments at all. I would agree that even semi-decent comments are far better than nothing. However, "no-new-information" comments are just noise, and misleading comments have a huge negative effect. I would not be surprised if an AI produced a large number of the former, and perhaps some of the latter.
