I mean, it's a challenging hypothesis to prove. I might just be pessimistic.

I think there is some reason for valid concern though. The New York Times memoriam for Clifford Nass is an interesting and somewhat worrying read.

Dr. Nass found that people who multitasked less frequently were actually better at it than those who did it frequently. He argued that heavy multitasking shortened attention spans and the ability to concentrate.

Maybe more practically, it's just hard to argue America wouldn't be in a better place right now if it wasn't for Fox News and Facebook/Cambridge Analytica.
