Currently, it's already considered very rude and an invasion of privacy/peace to be filming in a restaurant or public space and capturing neighboring customers or pedestrians, and even more extreme when it comes to the massive number of people trying to become streamers/YouTubers and who actually want to get as many of the other people in their video as possible.
But we are quickly approaching a further era, where people can disguise their cameras as glasses and front-facing lapels. And where technology will soon allow people to go around using AI to see everyone naked, and hooligans can easily create an immediate deepFake nude of your girlfriend or family and show you while you're riding the train.
Currently, there is no legal response to any of this (except perhaps mischief) in most jurisdictions. You aren't allowed to take their phone away, smash it, or punch them, and you there's no crime to charge them with. You can yell, but they can just film you yelling and laugh because you can't do anything to them.
What do you see as the outcome of this as it becomes even more pronounced and actual news stories of these things inevitably appear?
Will we pass laws banning all public use of cameras (except you are allowed to film even in public law enforcement, public figures, and anyone during a newsworthy event/crime)?
