The problem is not the technology, the problem is as she mentions in passing bad parenting. If it wasn't an iPhone it would be "talking through the landline" (remember ALF's starting scene? it was an issue for us kids in the 80s/90s) Cable TV, or marijuana or any other addictive passtime.
Fast forward 30 years, and we are doing OK. Things are different, but OK for us. "Videogames" have been replaced by "games" and we take them for granted and don't pay that much attention.
My take is that, for Generation Alpha kids, all the technology will be like bicycles or cars for us: It will be ubiquitous and they will all now how to use it. So there won't be any question about their use.
