I shouldn't be snarky but the value of seeing someone fixing or making something on video far outweighs that gained by reading about it in a book or looking at static pictures. You can see more easily how everything fits together, how much force you have to put on a bolt to loosen it, or whatever. The information density of a well-made video on such a topic is far higher than you'd get from a book simply because you can see exactly what's happening.
Different people at different times and under different circumstances; and different teachers with different methods can all impact the best medium to engage with content or learn things.
I'm happy you've found what works for you. At the same time, I'll continue to consider YouTube a viable source of educational content when I find it the appropriate medium for such, which is often.
Honestly, the real loss to educational content has been the loss of dislike metrics, which can very effectively tell you if content is valuable or not in the education space. At least it's been partly replaced by a "users viewed here" histogram, which can be a true help.
Wow that’s not been my experience at all - with regard to anything science or math related, I’ve found YouTube a massive help over any other medium.
Software engineering, not as much with a few exceptions (algorithms, cryptography).

This is how I feel about most books! I do hours of reading for something that could have been a few bullet points or a short video. Often finding the right book for your level is a challenge in itself
