Researchers shrink camera to the size of a salt grain
So privacy will evaporate. Imagine dropping millions of these from a drone, carpeting a city. They'd be carried everywhere on clothing, animals, wind. Go to any location and scan for local cameras, download.Privacy will have to be redefined. We've done this lots of times. You hear what goes on behind the bathroom door, you don't say anything, you actually forget it. Because it's not polite to snoop.So in future even if you see something you shouldn't on camera, it'd be boorish to mention it.That doesn't solve the police state of course.
