> Reading a book, reading a paper, etc -- these activities take discipline that most people don't develop or don't often apply.
Except some of the past moral panics were about reading books, they worried that kids were reading the wrong books, voraciously!
Reading popular fiction didn't used to be considered something that took discipline, it used to be considered escapist entertainment, people did it because it was entertaining.
Millions read books and newspapers (not sure if that's what you meant by 'papers'), only a couple decades ago. On the subway in NYC for instance, you would be surrounded by people reading both paperbacks and newspapers. Not very long-ago, in the adulthood of people currently middle-aged! It's not true at all that this was a rare thing undertaken only by people applying discipline.
It might be no big deal that this attention has shifted to social media, just another shift in the particular mediums used for cultural production and consumption. Without even getting into that debate -- just the fact that you believe that reading things on paper is something that takes discipline that few have ever developed -- is astonishing to me. It has definitely not always been that way. It was not that way literally only 20 years ago, not very long ago at all -- it is remarkable that things have shifted so quickly you now believe reading books has always been a thing only for those with discipline, to be done distastefully like eating your veggies.
(It could just be a shift in mediums, but the essay tries to illustrate the deleterious effects on our lives of the new mediums, which I recognize from personal experience and observation, myself).
