When Photoshop first appeared, image manipulations that would seem obvious and amateurish by today’s standards were considered very convincing—the level of skill needed to fool large numbers of people increased as people became more familiar with the technology. I’m sure the same process will play out with AI images—in a few years people will be much more experienced at spotting them, and making a convincing fake will take as much effort as it now does in Photoshop.
