When I was young, information was scarce abd it took day/weeks to access it - so the skill was to take time extracting as much information as possible from the few available sources.
Now the problem is exactly the reverse: information is so common that the necessary skill is quickly determining what not to look at. Video is very effective at preventing that.

I agree with your post.
In the old days (when some of us were younger), there were both good and bad things, compared to old and new.
In the distant past, there were lots of books available in libraries (effectively free) or to purchase (at reasonable cost for most people). These generally created trustworthy, high quality sources of information (within Electronics). But were not so good for computers, because a book was outdated (usually/often), almost before it was first available.
There were also less trustworthy, lower quality sources, such as Electronics magazines.
So for example, if a book gave you a power supply circuit. You could probably build it and it would work first time (not always), and perform as stated.
But if you built a similar power supply from a circuit in a magazine, it might work first time. But may need some messing about (even if built perfectly to the magazine circuit), just to get it to work well.
But that did probably help with the learning Electronics part of the exercise.
These days, (as you have already started to explain), there is a crazily large amount of information. Available 24/7/365, often for free, mostly available anywhere in the world (ignoring North Korea, and to some extent some other countries).
But the quality and accuracy of much of the information, is not necessarily 100%.
So you really have to be careful.
For myself (because I miss the old days), I think I (we) have to accept that the old days are gone now. Times have moved on, and things work somewhat differently now.
Although text is a very good and precise information medium. Video, can actually give you much more perspective (short of having the experience yourself), on how things really are.
E.g. My text might say that the ASR33 terminals were somewhat big, noisy, but fun to watch while they print from a paper tape. But by watching a video of an ASR33 doing that, it gives you a better perspective of it. To actually see one, these days (ignoring the odd museum, here end there), would otherwise be VERY difficult.
Watching such videos, brings back memories of what it was like, for me.
