The fact that you could potentially stream whatever you see all the time makes me wonder if there will be places where it will be compulsory to switch them off,

The fact that you could potentially stream whatever you see all the time makes me wonder if there will be places where it will be compulsory to switch them off, probably you won't be able to bring one at a concerts or sports event because of copyright. And I guess it's a safe bet that you wouldn't want to take it with you on a night out, because there's always someone who'd rather not be filmed while being underage drinking, or on a date with their lover or doing drugs. Just think of the implications of being in a bar knowing that potentially a few people in said bar might be filming everything that's happening.
