I'm not sure how many authors are aware when writing books, but it changes how you read it. With physical books I often peek a few pages ahead to the end of the chapter or just by the weight of the book know when I'm near the end. Sure, there are progress bars, but they're way more subtle. Knowing when something will wrap up I tend to have an expectation of what might happen. Without those cues I have a different experience. Similarly, my wife can burn through thick books without realizing it for the same reason. Previously, you may even be intimidated by how much is left, but now it's one screen at a time.
