Just consider how rapidly the costs of such technologies are dropping, and how much more rapidly they disseminate today than in the recent past, and it will become apparent that quite soon even the desperately poor will have access to them and more, and that the rate of dispersal will continue to accelerate.

While you may not feel that you are in danger of being surveilled, stalked, or otherwise need to recognize faces that may belong to professional thugs, you might grasp that some folks are, do, and soon will. The Stasi were not benign, and the FAANGs, enemedia, and political bureaucracies are more and more resembling them, as they become more desperate to continue to wield power.

I hope you will not tarry long before joining the ranks of we civilian non-combatants successfully gaining our freedom.
