I'm curious how many students would agree that textbooks are useful at all. My memories of college include actively finding ways to avoid having to buy textbooks and never opening a textbook if lectures were recorded. The best classes by far were seminar classes where the entire text basis for the class would be reading publications in the field - cell signaling and microbiology and others didn't have any recommended books at all. I don't remember ever using a textbook in a CS class either. I'm pretty sure GPT-4 would be infinitely more useful than a textbook in those classes considering we didn't use textbooks
