In the Steven Spielberg movie Minority Report (yes, I make some reference to it about once a week), there’s a scene in which John Anderton (Tom Cruise’s character) is walking through an urban retail center and his eyes are getting scanned as he moves, which is serving up custom greetings and deals from retailers. It’s both creepy and cool. But that movie is set in 2054, we’re not there yet. But AT&T had a demo at its Tech Showcase today that is inching closer to that.
