How will kids learn to communicate if their parents are constantly reading/texting?

I'm driving back to DFW from Shreveport and stopped on the way. I'm sitting in a restaurant. Been here 20 minutes. At the same time a young woman of the fat variety has sat down with her three children, which I estimate to be 5, 6 and 7. She has non-stop texted and read texts, scoured the Internet and just completely ignored her children, who have been trying to talk to her, but she does not respond.

This is troubling. These are times to talk and impart wisdom to your kids and teach them how to communicate ideas or to teach them about anything. Old fashioned, I suppose. Even at this moment, I've got my head down, so guilty of being on this device, but I was at several dinners the last few days and the older adults like myself only chatted, no phones out. My wife would smack me if I were doing that during meals.

Perhaps humans will develop and evolve into creatures with hands that grip the phone better and long, curved necks that don't get sore and stiff from constantly looking down and another set of eyes to watch where we're going, too.
