Right. I think we might have one sufficiently dangerous or infectious that people actually care.
I know of at least one geocaching/wifi exploit to achieve non-GPS locating; a virus using that plus having some use for the phone's location would certainly scare enough people to start a small crisis.
As we did last year, use this thread to make predictions for the next year and next decade, with probabilities attached when practical.
Happy New Year, Less Wrong!
