You may be right, but this isn't a helpful comment. Per the HN guidelines [0]:

    Be kind. Don't be snarky. Comments should get more
    thoughtful and substantive, not less, as a topic
    gets more divisive.

    When disagreeing, please reply to the argument
    instead of calling names. "That is idiotic;
    1 + 1 is 2, not 3" can be shortened to "1 + 1
    is 2, not 3."

    Please don't post shallow dismissals, especially
    of other people's work. A good critical comment
    teaches us something.
