I mean, people use dash-cams protect themselves in case of a car crash, so do you think people in the future would also use body-cams protect themselves in case of being involved in a fight?
Nothing would really surprise me. I am fascinated by that Black Mirror episode where they have cameras in their eyes and can play back anything theyโve ever seen, or download/stream for others to see. Even this seems totally plausible eventually.
You should check out Snow Crash by Neal Stephenson. It takes it a bit further โฆ
