Youtube "how to" videos are mostly useless

Quite likely. The tomes of formulae tggzzz mentioned and their popularity indicates the same.
As to "intuition", mine is all wonky. Sometimes it makes these leaps that end up being correct, without any pattern similarity. Sometimes it jumps off the bridge to the la-la land. I like my intuition, but I'm pretty suspicious of its correctness, too.
I call the understanding of the properties and behaviour without understanding the internal details "intuitive understanding", mostly for a lack of a better term, and because to me it is similar to being able to catch a thrown ball without being able to describe the trajectory of the ball (except in the crudest of approximations).

I can tell you with absolute certainty that my undergraduate engineering degree was essential. There is no possibility that it could have been replaced with book learning or watching YouTube videos (even if YouTube had existed back then).

Precisely.
"Push this button to floggle the spatchcock and make it yellow" should not form a central part of university education. It should be left to on-the-job training.

For repair work the visual aspect of a video is its greatest strength. Most of what I want from those videos is to see how things fit together. For most things its complex. If learning from books was so great, why would people spend a fortune to learn from lectures in colleges? Really smart people learn quickly from book, while less able people gain massively from lectures. However, even the smartest people pick up new things faster with a combination of books and lectures.

Remember the old Haynes manuals showing how to repair your specific type of car?
Once upon a time they were full of clear drawings showing the essential points of the next step. Then photo reproduction became cheap and easy, so unclear visually confusing photos were used instead.

I agree. The Haynes manuals have gotten worse. Often I try to find repair videos for the car but I find skipping through the videos in order to find the relevant 5 seconds out of 30 minutes a tedious job to do.

But that requires the look-at-me-merchants to have planned, in which case they would also avoid ums and ahs, and realise they haven't got anything worth saying.
Summary: not going to happen.

Considering how quick and easy it is to just record a video on your phone, then upload to Youtube, compared to actually writing the same information, I'd say you have hit on one of the core reasons for the proliferation of bad "how to" videos.

Where it gets amusing is when the first 30 minutes is spent dismantling and removing practically everything in the engine compartment in order to gain access to the part that needs replacing, with the mechanic calling down all sorts of curses on the engineers who designed it.
