Sora is even fooling human deepfake detectors

Our visual clues for identifying AI images are fading fast. 

It used to be that artificial intelligence would leave behind helpful clues that an image it produced was not, in fact, real. Previous generations of the technology might give a person an extra finger or even an additional limb. Teeth could look odd and out of place, and skin could render overly blushed, like something out of Pixar. Multiple dimensions could befuddle our models, which struggled to represent the physical world in a sensical way: Ask for an image of salmon swimming in a river, and AI might show you a medium-rare salmon steak floating along a rapturous current.
