No, the less cynical take is it says "the second half of the book drags on and you can skip most of those chapters." Which has been generically true of much business nonfiction for decades now. How people choose to apply that knowledge predates AI: skipping it, reading any of the summary reviews available, listening to the audiobook while in gym/car/shopping, asking a friend, dipping into it selectively, etc. There are lots of low-tech alternatives.
