That is like saying: "A perfectly good road needs no road markings". The point of of good comments is that they make the code faster to read and less ambigous.

That is like saying: "A perfectly good road needs no road markings". The point of of good comments is that they make the code faster to read and less ambigous. While good code should indeed already be readable and unambiguos, I have rarely seen code that couldn't be made even easier to understand and faster to parse by writing the appropriate comment. But of course you will have some individuals who think it is cooler not to, and they are probably the same people who think use after free bugs can be avoided by the shere willpower of the solo-male-genius that they are.
