An associated problem caused by a change in the mental model due to reading is the "Curse of knowledge" principle - which essentially states that "....better-informed parties find it extremely difficult to think about problems from the perspective of lesser-informed parties."

Once you have read something and your mental model of the world is adjusted to include the new information, you have a difficult time understanding why others don't see what you see. This is compounded by the fact - as highlighted by pg in the essay - that you also forget how and when your mental model changes.

This is one reason why not every expert is a good teacher - as they fail to see the world from the point of view of students.

But it is also relevant and useful to remember this in the world of startups. Established large companies routinely get disrupted by novice startups - often because the experts at the large company fail to see problems the way novices do. It is impossible to become an expert at something while continuing to view the world from the eyes of a beginner.
