I feel like this will be the thing that finally forces digital signing into the public eye. "Wait, is that video real?" "Well, it was signed by a reputable news source."
Right, which leads to a place where nothing is trusted unless it came from some central authority or from some trusted piece of hardware. I'm not looking forward to the day when I have to use e.g. an Apple or Google piece of hardware or some locked down kiosk or "be famous" in order to conduct business.
I assume trusted hardware would include things like LIDAR and biometrics, but if you're assuming those can be beaten then it will be a different kind of arms race, for sure.
