openstax is working on that too, for general college and AP subjects. They're getting assigned in some courses, but I think most professors are happy assigning commercial textbooks, often knowing that they can be pirated and that most students will pirate them. What's the justification for a professor to assign openstax Calculus instead of Stewart, for instance, other than to make a political statement? It won't matter in another few years once teaching AIs, a hybrid of LLMs and knowledgebases and logical inference engines, can take the place of textbooks and teachers for non-specialized fields. That'll be able to handle almost all K-12 and lower level college subjects, and teach better than most human teachers. Traditional education may not matter by then, though, depending on what AI does to society.
