If bad actors decide to release an AI-generated or computer-manipulated video or images of Joe Biden doing something that would sink his chances at a second presidential term then the world’s attention will fall upon them and every pixel will be minutely dissected by the best in the field. If images circulate purporting to show microbes in the soil of Mars, they will be examined forensically by the world’s experts. In both cases, I suspect the truth will out. But what happens when it’s not the headline-grabbing images that are manipulated, invented, or created by AI? We’re taking in hundreds, even thousands of images a day - the vast majority of which we’re giving no second thought to. It’s here that we’re most vulnerable to this kind of manipulation.
