It isn’t about the specific mode of distraction, but that most people can’t go without it for any length of time. The ability to just “be bored” and allow your thoughts and observations of things around you to ebb and flow, without some sort of instant gratification, is a skill or discipline that is eroded by content stimulation. In the same way the discipline of a balanced healthy diet is eroded by empty calories and super caloric food that messes with your reward centers. If I say I am the only one that can avoid grabbing a donut when they are brought into the office, it isn’t about donuts specifically but an illustration of the broader problem with food.
