This really captures what I think is the main problem with our state of being constantly distracted: it feels at first like a relief from anxiety, but ultimately results in even small anxieties never properly being dealt with. The end result is a vicious cycle (or I guess virtuous if you sell online ads) of becoming more and more anxious causing us to rely more and more on the screen to distract us, which in turn only increases that backlog of anxiety.
I see this happen in a lot of younger people that are constantly on screens: they frequently mention their need to "chill for a bit" and yet spend most of their time doing nothing but staring at a screen. It's clear that they are living in a lukewarm vat of anxiety that they can't face while staring at a screen, but also one which causes them immediate stress when they do look away.
