If I have a random picture, video, text - it's not easy at all to verify its authenticity. Hopefully a media organization has it, but even then are there any services I can use to validate? Definitely not family/personal media, any media that wasn't reported on by a large organization with the ability to manage large archives of data. I'm saying this is going to become increasingly important fast, and we may miss the window where now almost everything not properly indexed by a large media organization is invalidated as there is no way to verify it. I have a picture of Frank Sinatra at Disney World riding the tea cups. Who is the Frank Sinatra media authority that can tell me if this ever happened or not? A very small example to extrapolate from. It's going to get worse when everyone can create audio/video/pictures/text of anything they can dream. The past may very well become a fictional dream, mythology, most of it impossible to verify.
