Were we talking about the difficulties of understanding what one reads...?

Are there differences between online reading and print reading?
"The brain is plastic throughout its life, it constantly adapts," explains Wolf, who is one of the world's leading experts on the study of writing and was struck last year by the discovery of how her own brain seemed to have adapted as well.
After a day spent on the web reading hundreds of emails, she sat down to read "The Glass Bead Game" by Hermann Hesse, and "I am not joking: I couldn't do it. It was torture to manage to finish the first page, I couldn't force myself to slow down: I would select useful words, organizing my eye movements to gather as much information as possible in the shortest time possible. I was ashamed of myself."
The brain is not designed for reading. There are no genes for reading like there are for language or vision. But driven by the emergence of Egyptian hieroglyphs, the Phoenician alphabet, Chinese paper and, finally, Gutenberg's printing press, the brain has adapted to read.
Before the internet, it read mainly in linear ways: one page followed another, and so on...
Internet is different. With so much information, linked text, videos, mixed words, and interactive things everywhere, our brains create shortcuts to navigate, scrolling quickly up and down and searching for keywords. It is a type of non-linear reading that has also been described in several academic articles. Some researchers think that for many people this reading style is becoming predominant even when we deal with more traditional reading tools.
mmhmm
It seems very interesting to me and perhaps (I don't know how much) worrying
