Remember the author is talking about helping beginners learn programming. Not you, HN user with 10,000 karma, and maintainer of five python projects. There's a case study in the Christensen's Innovator's Dilemma where a company tries to improve its milk shake by making it more chocolaty, by putting whipped cream on top, etc but for some reason this doesn't increase sales. Then some guy goes into the restaurant to figure out “What job do people hire a milkshake to do for them?” and it turns out its not the job the people making the milk shake thought[0]. I wish the core python developers would do the same and ask themselves not how to make the best milkshake, but why do people buy their milkshake in the first place?
