I've come to strongly dislike this quote, because it's so often used on HN to decide that whoever's disagreeing with you is doing it for simple, stupid and greedy reasons, thus absolving you of the duty to think a bit about whether there might be nuance you're missing.

We all have limited cognitive budget. Keep nuance investment were there is relevancy for it makes more sense than spending it on things where it’s not going to bring any value to anyone.
