One theory I have found pieces of and put together is that a primary pillar of mental health is how your life experience as an adult matches your life experience as a child. If most of us are going to spend a significant amount of our lives glued to screens in order to be productive members of society, at least introducing that early might make the matching experience more tolerable.
It's not like they had any chance of lacking screen time through their childhood with schools as they are. Nor were they deprived access, or lacked natural ability come 5 and 6 on... Or lacked inclination to become addicted to WoW come 13 or 14.
I'm not sure what you mean with your point about "life experience as an adult matches your life experience as a child". Maybe I'm completely missing it. For any of us born before the home computer revolution of the 1980s, childhood and work are likely dramatically different things. I'd rather the kids get a chance to be children than start preparing them for a life of work at age 2 or 4...
Lavish your child with praise and attention, everything they could want and making sure everyone is successful at everything and never "fails" ... come to the real world as an adult and reality isn't as nice, the world isn't actually like what you grew up in and your feedback systems simply aren't equipped or designed to handle the situation life puts you in.
We do push it at times when we are traveling or she’s sick where she will get 2-4 hours of iPad and videos along with her books. She will also pick a book over the iPad almost every time the choice is available so I am not worried (yet).
