Only AI can save us from a world of fakes (a world AI is also creating)

The truth is out there. When I was a kid, my brother and I made a UFO out of paper plates, tin foil and marbles. Then we got on the roof with our spaceship dangling from a fishing line and, using our mom's plastic 110 camera, captured incontrovertible proof that we are not alone in the universe. But when everything went digital, creation and distribution both got easier, faster and more broadly distributed. And artificial intelligence (AI) will take it to a whole new level, enabling anyone to create perfect fakes of difficult-to-fake media, like video and audio.
