I remember the 1990’s when morphing¹ was all the rage, and everyone was fascinated by the effect. (It was very common among those who could afford it, and could be seen in movies, TV shows, commercials and also, weirdly, on book covers.) Nowadays, the morph effect looks unbelievably crappy, and obviously fake. The same can be said to have happened to all older forms of special effects; we all now cringe at old movies’ stop-motion animation, rubber monster costumes, and plastic gadgets, but at the time, people thought they looked real.
I would bet that the same will happen with AI-generated images; people will learn to tell the signs, and artists will have to learn to avoid these.
