I agree with the last sentence, but not the first and second. The first implies that the only way to learn computer science is in school, and the second attempts to stereotype products built by those who drop out of college. I understand the sentiment, but I think it's possible to both create real value and not go to school. That's one of the points that this article is trying to make. I also think that framing all hard problems as engineering problems is an engineering-centric view. Depending on the product, sometimes designing the user experience to be seamless is just as hard as building the technical foundation.
