I don't think YouTube replaces school for most people, but it makes it possible for someone who wants to learn something to do that much more more easily than before. School forces kids to learn a little bit about a wide-ish swath of subjects. Youtube enables them to go deeper on whatever it is they're interested in. Finding and signing up for a class or lessons is a big, expensive hurdle, and then you might discover you hate the subject or the teacher. If you can quickly and easily dip into a dozen subjects and try videos from hundreds of creators, you can rapidly try and reject things until you find one that strikes you and stick with it. The Internet in general does this, but YouTube is a big part of it, especially things where visuals are useful—woodworking is a good example, but there are so so many things to learn if you can jut find a subject and a teacher that catches your interest.
