If there are no rules in art, then white George Washington should be acceptable.

But I would counter that there are certainly rules in art.

Both historical (expectations and real history) and factual (humans have a number of arms less than or equal to 2).

If you ask Gemini to give you an image of a person and it returns a Pollock drip work... most people aren't going to be pleased.

Art doesn't have to be tethered to reality, but I think it's reasonable to assume that a generic image generation ai should generate images according to reality. There's no rules in art, but people would be pretty baffled if every image that was generated by gemeni was in dr seuss's art style by default. If they called it "dr seuss ai" I don't think anyone would care. Likewise, if they explicitly labeled gemini as "diverse image generation" or whatever most of the backlash would evaporate.

If you try to draw white George Washington but the markers you use keep spitting out different colors from the ones you picked, you’d throw out the entire set and stop buying that brand of art supplies in the future.

Because white people exist and it refuses to draw them when asked explicitly. It doesn’t refuse for any other race.
