"University professors are now saying they are unable to teach history because reading long books and passages is how a person learns history."
Sounds more like that's just how they want to teach history, and probably because it's less effort on their part.
Students being "incapable" (probable more like unwilling) to read a lot is certainly an issue, but let's not pretend it's the only way, or even necessarily the best way for everyone, to learn history.
If you have enough of an interest in a topic, you'll be willing to put in the effort.
I don't think anybody really grasps how desperate this situation is.
University professors are now saying they are unable to teach history because reading long books and passages is how a person learns history. College kids are incapable of reading more than a few pages.
Some classes don't assign any reading at all now, only lectures.
There is an assumption among the people managing this decline that reading is just a way of receiving information. It isn't. Proper reading is how we build the mental muscle to synthesize ideas and evaluate them.
If the catastrophic decline in reading and literacy is not addressed now, we risk losing everything.
Western civilization cannot survive the death of reading because it was built by people with the kind of cognitive depth that a culture of deep reading brings:
Complex reasoning, extended internal dialogue, the capacity to hold opposing ideas in tension. Our systems and institutions are complex, and they require well ordered minds to maintain them.
Reading forms minds, and the West was built by the richest minds in history.
