Yeah I definitely agree with this. If I'm incrementing x in such a way that it's pretty clear what the meaning is (e.g. it's actually called like cur_page or something and I'm iterating over paginated data), then comments don't add a lot of value. Especially if they're not actually kept up to date with code changes. On the other hand, comments like, "Hey don't change this because if you do, it'll break things in subtle and hard to test way because x," are definitely useful.
