This is like saying tribal knowledge is useless, or internet access is useless. Books are useless only if they’re inaccessible. The point you’re trying to make (I think) is that information isn’t particularly useful on its own. True. It has to be relevant. With good, useful information you still need community support (whether that’s your household or your country), funding, time, etc. But that’s going to be the case whether you’re using a book or learning from a forum, or a video. Internet videos are worthless if you have no internet. Tribal knowledge is useless if no one can get the information from the previous generation. The medium is not the problem, and suggesting that relevancy is a fault of the medium is a misrepresentation.
