(this is likely where the norms around recording will end up - reinforcing the existing power structure)
Only you didn't realize that woman was recording her daughter when you walked out of the hotel in front of the park. Now the video is public on social media, and people can use the new fangled "Are We Dating the Same Guy/Gal" facial recognition models to basically run searches that would not have previously been possible on all public videos on a site. Search might even be geo-fenced to make it faster? Who knows? Point is, it allows them to find you coming out of that hotel in the background with your "friend" from work.
Keep in mind, it might not even stop there? Now when you approach a girl or guy you may be interested in, maybe in class, maybe at a party, whatever, his or her new fangled "smart glasses" may now bring up a huge red blinking "DIRT BAG" without you even knowing it.
Maybe ubiquitous tech like these body cams are necessary? I'm just asking everyone to think down the road a bit, (not even very far down the road honestly), and ask yourselves if maybe we can be a little more creative about solving some these problems by means other than ubiquitous gaze?
