I disagree with the author. Yes,there are some things out there that are very difficult and people don't try to pretend they are not(e.g. quantum physics, biochemistry,etc.). However,very often,it's the middle part between you and the subject. For instance a poorly written book can make any subject challenging.A poor teacher can make even elementary things hard to grasp. Poor communication can lead to situations where nobody would have a clue anymore and etc.And the worst part, especially in our so beloved tech industry,is that quite often the loudest voices are exactly the ones that should be kept quiet at all costs to make things less difficult.
