While I agree with you, the problem is far bigger than any one company in my opinion. These tools are already accessible enough to individuals that no audio or video is trustworthy, regardless of its source. I suspect we can still detect whether most faked audio/video is authentic or not algorithmically, but that's going to turn into an arms race eventually. And IMO none of the "answers" are ones that you really want to see made real, either.
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.
We're in for some really strange times.
