Not to be snarky, but I 100% need some kind of source for that claim. My experience in higher ed is the literal opposite of that.

I see mainly young people also struggle with reading comprehension skills so they might be learning faster (in their own pace) mostly because they can't read effectively.

I haven't written a paper about this, this is an observation looking at kids and youngsters around me, mainly, economically speaking, middle class and also lower middle class. My sample is around 100.

I also see issues with reading comprehension but not video comprehension. I am not saying that things are better now, just saying that observations should be balanced. A person interested and with attitude towards a specific topic can navigate the learning path with more resources and less friction.
