Everyone seems to be discussing whether the author is correct about claiming that "people only really learn when surprised", he wrote it that way to give emphasis to what he had previously written, not really used it as a fact.
So this comment section became a battle of proving the author wrong, when in reality, he has actually written a very interesting piece with a nice hook. I don't understand why people nowadays can't just take the good part, the lesson learned and move on.
It seems like HN has been going downhill since years and it only gets worse. Sad. Well, that isn't a surprising message right? Maybe I should have omitted it.
