Normally, what amounts to a longitudinal study of teens' phone/social media usage throughout the entire pandemic plus one more year would be a fascinating study and right up my alley.
But I must confess: I barely finished 1/4th of the series.
I just found watching teens text one another, scroll mindlessly for hours, then cheat on exams by using their phones literally in class to be nails on a chalkboard for me, a bridge too far, a burr under my saddle, a pebble in my shoe, the nail in my coffin.
Insert your own cringy idiom here, and there you have: something so unpleasant that, findings or not, the destination just ain't worth the journey required to get there.
