Del Walker, a senior character artist for the video game developer Naughty Dog, told AFP that distorted faces and limbs, gibberish text, "hypersmooth" skin, and objects with odd features are all signs of AI manipulation. But he cautioned that such red flags "can be improved in future AI updates or easily edited in image editing software." "The only real kryptonite for AI is skepticism and scrutiny of all images," Walker said. DiResta of the Stanford Internet Observatory agreed.
