This comment breaks the HN guidelines against name-calling in arguments, and also against snarky dismissals—especially snarky dismissals of other people's work ("sorry professor... ok?"). It also breaks the guideline that asks: "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize."
The internet comment genre makes this sort of thing nearly irresistible to post, but on HN we all need to resist it.
