Adult with ADHD here: You would not develop ADD from media. That's not how this works. The fact that devs have found ways to design sites that mimic patterns for addiction doesn't mean it's the people. It's the things. If you suddenly found yourself removed from the stimuli, you'd be fine, no longer the exposure period. I will not.
Since our jumping off point was "people are getting dumber"(they aren't) I just want to point out people aren't also developing ADHD, they just have more things vying for their neurtypical brain's attention.
