Well, I think people brain start to work differently in internet. For a example when you read a text in some site, unconscious, but it is in most people, the main idea is whether to share it, whether the others will thing you are more interesting if you show it to them and so on. Not really to understand it. When reading a book, this is not the case, you are completely in-depth in the text and you try to understand it. So maybe the digital space itself seems to have the nature for short answers and superficial insights. Spiritual fast food.
