Agreed. People already are fooled by all sorts of images, and video, real and fake.
And not only do they not believe photos or videos, but even press releases coming out of the government is continually perceived by large swaths of the public as untrustworthy. And another huge portion of people don't trust the independent media.
This fake video things is just yet another tool that the good guys are going to have to fight against to try to bring a common sense of truth and facts back to the world. How do we start to get people to trust "news" and "facts" when everything is so tainted with bias?
An interesting thought I've had recently is about having a future where there exists a "global media" state, where they as a state only exist to serve the interests of journalistic integrity in every nation around our planet.
Members (or citizens) of this "global media" state would be people from all over the world who decide to no longer pledge loyalty to a flag or constitution with the best interests of a "nation-state" in mind. Instead, they pledge to some globally accepted constitution and rule of law and integrity and only exist to expose the truth to every person in existence.
Of course there would be tons of safeguards to define what could and couldn't be accepted as "truth" and it would have to be above any religious or spiritual law, and instead only serve the best interests of expanding human knowledge and survival.
