So I'd say that no, it's not that phones are like crack. There seems to be a disconnect on the parent's expectations when children discover the possibilities of a technology that's unfamiliar to them. In the article they're talking about the ease of controlling TV time but that doesn't even compare in possibilities of communication, entertainment and education.
Heck... I'm sure if you could go back in time you'd discover the first generation to grow up with books, and their desperate parents noticing how the kids aren't ... working the fields and feeding the cattle, I guess.
