Almost everything is hands-on (everything apart from things you really can't do hands-on, like exploring black holes): I don't remember seeing someone come out of reading a book on programming and being a master programmer.

But video is not hands-on any more so than text: if it was, live concerts and sports games and other performances would not be such a big deal. Sure, video is richer in some signals (audio/video), but poorer in others (introspection, pacing and focus...).

That does not mean I can't read to understand a new topic or to be prepared to look for subtleties in a hands-on performance.

If anything, to a great student, they should be complementary, but still, each student will have one or the other contribute more to their learning, and that depends both on the teacher, but also on the student.
