Nostalgia for the days of giant cellphones and invisible photographers
In the days of the big phone the call was theater. Now the call is in the service of ever shifting plans or to assuage general feelings of disconnection. I conjecture that entire groups of people now have have un-purpose driven lives and use the ubiquitous cellphone to get the next set of directions from some extra-planetary overlords who control the general population via microwaves. It could be that the person next to you taking snapshots with their iPhone or their Verizon Punk phone is really just triangulating your position so that the overlords can assimilate you as well. I also get the feeling that cellphones are largely responsible for adult onset Attention Deficit Disorder. Never have I seen a person change gears and go from a full out, impassioned conversation to a passive and submissive listening mode as quickly as in the past few years. A Pavlovian respond to a tiny few square inches of plastic and Lithium Ion.
Perhaps this too shall pass and people will go back to diligently practicing their lives with purpose, picking up their phones once or twice a day in order to check messages and return calls. Maybe that's the hope of economists optimistically calling for enhanced productivity to pull us out of the economic mess. Naw, the nature of the universe is to constantly move from order to chaos. From momentum to entropy. Why should humans buck the trend?
