Unfortunately bad comments like this leads people into thinking that all or most comments are useless.

It's true that I don't want to see a comment like "loop through this 50 times". But what may not be obvious is the purpose of the loop, the significance of the number 50. Putting in "why" can save hours.

The only exception where I would want a comment that just says what a line of code is for a really complex line, like a complicated regex for example.
