To the first and second groups, all I can say is good luck, your corporate overlords will be delighted to hear you think this way and the government will be stopping by soon to tattoo a Q-Code on the back of your neck.

As for the last comment, I sort of agree that it's all gone too far, but whether it's too late is a matter of debate. For it to be too late you'd have to assume that there is no more personal privacy to be lost, that the full scope of how you can be sliced and diced by the government and the corporations has been achieved. This is, thankfully, not the case.

So, what might erode your remaining privacy? In the seemingly endless parade of new threats, there's an issue that has been brewing for some time that's starting to become really big: Drones.

Drones are remotely piloted aerial devices that carry surveillance gear in the form of conventional cameras, radar, cellphone eavesdropping systems, thermal imagers, and UV cameras (and if the drone is military, it could well have guns and or bombs). They can come in the form of airplanes, helicopters and even balloons. They can be the size of bombers or birds (there are, not surprisingly, university projects that are starting to build flying devices the size of insects).
