Right, but, then what? If you throw away all of the books from experts, what do you do, go out in your backyard and start running experiments to re-create all of science? Or start googling? What, some random person on the internet is going to be a better 'expert' than someone that wrote a book?
Books might not be great, but they are at least some minimum bar to reach. You had to do some study and analysis.
Seems like any critic of books, if you scratch the surface is just the whole anti-science/anti-education tropes again and again. What is the option? Don't like peer review science, fine, it has flaws, propose an option.
