So the mother's cell phone usage contributes to the child's brain development? Rrrrriiiiight. Keep dreamin'.
Having been a "latchkey" kid for my youth, since both of my parents worked long hours with long commutes, I can understand where you'd get the impression that day care kids are not given enough attention, but you're completely wrong.
You say that the parents leave the kids 40+ hours a week in daycare, then allow them to watch TV 50-60 hours a week as well? How many hours do you think there are in a week? That means they're not eating, doing homework, playing outside, etc., because with 7-8 hours of sleep each day, you're telling us they have no time to do anything else. What is it, wake up, daycare, TV, bed? Lather rinse repeat?
It's not inattention that makes kids autistic. IT IS A BRAIN DISORDER. Yeah, leaving kids in daycare doesn't give them a lot of parental interaction time, but the interaction with other kids at daycare is certainly enough stimulation. Cell phones? ARE YOU SERIOUS??? Autism rates were climbing before widespread cell phone usage, folks. It ain't the phones!
Again, this is not about parental inattention to their kids. This is a developmental disorder, not an everyday occurrence at your local mall.
