The author seems to be focused on low-quality reading, both in terms of the material itself and in terms of habits formed while giving the material the (scant) attention it deserves. He says we encounter almost half a million words daily. No one is giving that stuff a deep reading, or should.
The culprit is probably work. Think of how much of the typical office job involves ingesting low-quality information at high speed. The jobs aren't mentally taxing, but they do burn you out from serious reading, because of all the time wasted on peoples' shitty emails. You basically need to become a skimmer to survive modern life, especially if you work an office job, and there's a nonzero amount of mental effort in code switching from serious reading to half-assed work email reading.
