I definitely don't disagree with screen or exposure or social media exposure being deleterious.

That said, I suspect this technology will allow us to study and mitigate those effects in ways we weren't previously capable of. That's in addition to the other broad swathe of things that should make us healthier and more intelligent (see some of my other posts here). I'm not particularly negative about our chances.

I do hope for an optimistic outcome of course. But the same cohort that gave us algorithmic screen maximisation is also funding and leading the AI revolution so I'm a bit sceptical they have our best interest in mind.
