It strikes me that perhaps the prompts are not expansive or expressive enough. If you look at some of the prompts our new wave of prompt artists use to generate images in communities like midjourney, a single sentence doesn't cut it.

If AI is just compression, then decompressing a generic pop-culture-seeking prompt will yield a generic uninspired image.

Exactly. The AI understands that reference. It gives you what you asked for, it doesn't try to divine that it's a weird test for IP violations. If it made up a different image, that would be exactly the thing we're mad about with "hallucinations" when we want serious, accurate responses.
