This feels dystopian to me too, not least because in order for software to diagnose this problem you'll need to spend sufficient time generating relevant usage data... usage that will (if existing social media are anything to go by) be a net contributor to problems with self-esteem, fitness, sleep, etc.

I'm not going to pretend to know exactly what he means, or how it'll pan out, but the cynic in me is expecting a greater net benefit from just deleting your FB/Twitter/Insta account.
