"and invisible is coming"

No.

There is no support for the idea that communication or any technology ever becomes invisible. Quite the opposite. Pervasive and corruptive is much more accurate. Cars, planes, telephones, PC's, blue-tooth, are all disruptive technologies that strain the fabric of society in ever increasing ways. Pervasive, yes. But Invisible? Not in the least. My wife teaches. Recently emails were discovered detailing sexual assaults...DETAILING assaults on fellow 4th and 5th graders.

Is this changing the kids? I think so.
