So that the drones can track your every move. They already have the capability to kill you. The Terminators can't be too far behind can they? I guess we potential prey for these things need to develop and stock up on DIY counter-measures like EMP technology and homemade RPGs. Hiding out isn't gonna be an option much longer. And as we learned from the movie you can't kill Terminators or drones with simple small arms fire.
