The end?
However, imagine a future in which these fake computer-crafted videos are good enough to fool enough of the population to spread fake news, or doctor evidence to frame people for crimes they haven’t committed
If it gets that bad, and the populace are well aware of the fact, then I don't see how video news reporting can survive at all. Likewise the use of video as evidence.
People will only trust what they see and hear themselves. Actually that's pretty much where we're at already.
