Killer Apps for 2012

The apps that usher in a major jump in the global economy.  My choices:
TrailerBot - The self propelled, small autonomous vehicle that mimics a trailer.  This is the simplest of the Autobots, already in existence in the lab.  It will simplify moving cargo all throughout, and accelerate the drive toward smaller cars.
Then I am split between deliverbot and ultra high speed trambot.  These two follow right on the heals of trailerbot.  Deliverbot works best with standard curbside mail boxes.  But Trambot and its cargo equivalents move huge amounts at ultra high speeds over good asphalt roads.  They can traverse small streets with traffic light assist and still cruise the highways at 140 MPH.


Trailerbot is still the key, with enormous utility and an AI framework that just mimics a steel frame.
