After a short discussion with Aristos & Vera, I would like to share the following train of thought where Screen is concerned:
The internet is a product of industrialization & technology. It is changing the way we read and access information, and the way we think, but not necessarily in a bad way. The internet is a powerful browsing tool, and it serves just that purpose. To rely on internet for in-depth research is less effective. A book would serve this purpose better.
The only difference between browsing from internet and browsing books/ content pages in library is the absence of having to be physically there. However, it does not mean browsing on one is more effective than the other.
The reason why many people find their attention span has grown shorter, making concentrating on a book difficult, is possibly because their brain is used to the way of accessing information on the internet. They are unconsciously applying that method when reading a book.
The internet can make us lazy. Even more worse for graphic designers to rely on internet findings to solve creative problems. On its own, internet is an educational tool if used right. In TED 2007, Sugata Mitra carried out experiment on uneducated children in India on their own with PC. Technology helps. With Internet, children can find answers. Their interest in learning is triggered. A book may appear less interesting in comparison, because it lacks interactivity.

I do agree you call the internet “browsing tool”. The way people browse online seems a little bit lazy, and that is why the author says: We can’t read. In my opinion, this is caused by HYBERLINK which leads us to dig deeper or to be distracted. Obviously, it depends on how people feel about the information. For example, if a gossip is shown on BBC website, many people tend to “click” that link or maybe google the topic for absorbing more details(videos or images). In this case, most people ARE STILL ABLE TO READ. I suppose, at least the net provides the opportunity for satisfying curious human beings.
