I find videos are a convenient way to get an overview of something I'm interested in, yet not so deeply invested in that I want to learn it in depth. In other words, I can do the chores and learn a bit more about the world in the process. In that respect, I would say that reading is much less efficient.
If it is something I am interested in learning in depth, then I would agree that books are usually more efficient.
Well, with a caveat.
Some people appear to record themselves as they pursue their hobbies, then post it to YouTube. (Sometime's it's organic. Sometimes it's partially planned out.) In those cases it is a bit like a very one-sided mentorship. The host will either realize they're doing something that they would never write about, whether it is in a script or a blog or a book, then discuss it. Other times they don't make note of what they're doing, for the same reason they wouldn't write about it, but you see it because they are doing it. Written communication can be lossy.
