You clearly have no idea what you're talking about. I hope I never get stuck cleaning up your messes, but chances are that someone as intellectually lazy as you -- if not you -- will leave me an uncommented code base to maintain.
The fact that you actively advocate intellectual laziness is distressing.
Further it's utterly astonishing that you would equate writing clear and non-ambiguous code rather than nebulous code of uncertain purpose -- like the example Chromium code you linked -- is "intellectual laziness". That you hold good coding as deficient compared to lazy commenting is hardly surprising given your comments.
"I don't need to comment" is really "I don't want to document my work because that's boring and I'm much too smart to need to do that".
You're not that smart. If you were, you'd realize just how dumb everyone is, and thus, just how necessary comments are.
