…something something privacy…
It'll only keep shrinking, until it is the size of dust particles, just another order of magnitude.
How do you prevent dust-cameras from being around? a pre-emptive EMP pulse lol?
1- Actually, the main problem with privacy is that most people still doesnt really care and many more underestimates its current reach, if this were somehow to happen, proably it would raise awareness and that is of topmost priority. 2- Its is already mindboggling. 3- A spy needs privacy to spy.
