No, it's not. Read the rest of his comment. I agree with it wholeheartedly. The article describes a terrible way of surfacing a new idea, and if you keep trying to get buy-in that way, you will keep failing.

> It doesn't help to waste oodles of time learning about mistakes made by others under different contexts and constraints.

Intelligence is practically defined by the ability to learn from others' mistakes.
