Intelligence services of the world, are you listening? There is something to learn from the way these companies have managed to create themselves an army of informers. First they managed to convince people to pay for their own personal tracking devices, putting one in nearly every pocket. They come equipped with microphones and cameras, with satellite positioning, with everything you could wish for to keep tab on your subjects. Next they managed to convince them to use those devices to create a detailed profile of their interests and their friends and relatives, there to be perused at will. And now they've gone a step further, convincing them to put microphones in their domiciles, always listening, net-connected, recording all the time. With voice recognition to ease the transcription of anything of interest. If anything these commercial intelligence services suffer from an overload of data on their subjects, not a dearth of such as is the usual case for governmental services.

Note to current and future governments: outsource intelligence gathering, it is much more effective that way.
