Yeah, privacy in meatspace is a lost cause. Cameras everywhere. Around us. Carried by us. Overhead. Plus DNA sampling. Total surveillance.
Even so, here in my office, there are no cameras. And only heavily draped windows. And no audio, for anything that's private.
And so it's only my online activity that can be at all private. What a strange world.
It won't matter because of all the cameras under the canvas. Cell phones will continue to track every person's location in real time. You can try to hide from the satellites and drones, but you can bet that your every movement will still be tracked somehow.
