Will we come to accept this as the ubiquitous norm?

If you've seen the movie "Minority Report" then perhaps you agree that the creepiest part of that movie is the acceptance shown by the general populace regarding universal tracking via retina scans.  You get on a subway train and blink-blink you're tracked.  You enter a building and blink-blink you're tracked.

Everywhere.

Which is creepy.

But the populace is shown to just ignore it and let it happen.  Is this our future?  Because the calm acceptance is creepier than the act itself.

Well...my alma mater, the University of Washington, is researching the impacts of a similar technology. 

RFID tracking.

"What we want to understand," Borriello said, "is what makes it useful, what makes it threatening and how to balance the two."

They are interested in the implications, applications, privacy and restrictions.  Their explanation is that it is better to test now and understand the ramifications before anything is implemented in the real world.  Better the devil you know as it were.

It's still creepy.  It's also probably easier to implement in the real world than you think.  Just require the next generation of cell-phones to contain an RFID chip.  Done and done.

Like I said...creepy.
