You might be right. But apples and oranges are both fruit. I imagine that lots better videos could be made than the ones I have seen.
Getting back to washer repair, video lends it self well to conveying this kind of thing. When a repair step is conveyed in written words, it can be hard to understand and apply. When the guy tells you the next step, and shows you himself doing that step, it's easy.
One way to make abstract concepts visual is diagrams. I used to use diagrams out the gazoo when I was teaching database stuff. I would expect that by now there would be "animated diagrams" out there that illustrate a time varying process by making a movie out of it. No such luck. Hell, they don't even use still diagrams as effectively as I did back in the day of acetate transparencies.
What they do is dive into how some tool, like "visual database studio" works, and tell you which menu choices they are making, withough explaining what the menu choices mean, or without telling you how you would design a database before you begin to build one. I regard menus as trivial, unless the menu creator was being perverse. That's not what the subject matter is about.
By the way, there are no good videos out there, to my knowledge on the subject of how to design a better washer. Maybe that's the difference.
