@PK,It again comes back to YOU, yourself, to what you are looking for? Do your own due diligence if you want to buy a book in itself or learn from the online videos. As for me, these online videos helped me at times when I got really desperate to find solutions to my problems on table. Things are constantly changing and moving pretty fast. Like you said, nobody has time to watch videos over 100 hours and you have said it yourself videos are difficult to make and repair easily. So how can you expect them to be not "surface-level"? The answers were there in your own write up itself. If you want more information, yes you have to dig deeper. And you as an intelligent soul, knows it very well where to look.
Filter out the videos that look trash to your taste, come on, nobody is forcing you to sit through the whole ordeal! The way you challenged people for their IQ who have been to watching the online videos, it is very opinionated and less informed.
Lastly your statement "I'm in the shithole, Nepal!" is quite disheartening. Buddy you need to give respect to where you belong to and where your identity is related to. I may have some differences with the way things are done there in Nepal, but I would not never disrespect the country I was born to.
The rest is on you.
