I also see that in real world too. Too many times I wished a book existed to learn this or that and got an answer that you really need to hang out in multiple Discord groups to stay up-to-date. Newer generation apparently has less difficulty with that.

Also I found videos to be of enormous value to learn visual tools like CAD. Just watching someone do the job and explaining how they do it lets you fill the gaps that theoretical education leaves open.

Maybe they just think they do because they don't know any better?

Or constant stream of information gives them the illusion of staying informed
