However, there is a line in 'The Incredibles' that goes something like this: "When everyone is special, then nobody is special."

Do you really want to get pissed off and scared? Then consider the following. Hovering insect sized spybots will likely infest your home in the future, and it won't be the government's spying that will give you cause for alarm. It will be the fact that it may be your neighbors and enemies and companies you patronize which are the ones doing the spying on every private moment of your life.
