Interesting read. The author says its not a rant but it reads as a rant. However it also has a fairly clear and concerning message: attention spans of current students are dire and its down to smart phones.
Some elemenrs of the piece are off though. Laptops in class are essential -its a far better way to take notes than handwriting for many people. But you also have to treat students like adults and trust them - if they want to sit in a class and gamble then thats their problem. While there is some overlap with the phone issue it is different.
There is nothing much the author can do about the main issue than sound the alarm. Social media is designed to give people dopamine hits and be addictive, and were seeing the effects of that addiction permeate through society.
The response to anyone reading that article is to get off their phones. Lock it away when youre in the gym, lock it away when in school or work, leave it in another room when its time to go to bed. Break the addiction.
