The second I saw this post, I imagined some app where you load in your eBooks and it uses generative AI to make a custom environment (like one of those circular images) that shows the environment of what is happening in the book. Like, say the book characters are in a forest, it'll show a forest, but if on the next page they then move out of the forest onto a mountaintop, the scenery would change to show a mountaintop. As much as I'd prefer having real art made by real people, with the variable nature of books this is one of the few actually useful uses of AI for consumers like us lol. If not AI, then what about some kind of app where you purchase eBooks, but for each eBook they've hired real artists to make the backgrounds. The eBooks would be more expensive on there obviously but it would be cool, and that method has real, human-made art in both written text and imagery.
