That indeed sounds like a very plausible solution -- working with AI on the level of scene definitions, model geometries etc. However, 3D is just one approach

That indeed sounds like a very plausible solution -- working with AI on the level of scene definitions, model geometries etc. However, 3D is just one approach to rendering visuals. There are so many other styles and methods how people create images, and if I understand correctly, we can do image-to-text to analyze image content, as well as text-to-image to generate it - regardless of the orginal method (3d render or paintbrush or camera lens). There are some "fuzzy primitives" in the layers there that translate to the visual elements. I'm hoping we see "editors" that let us manipulate / edit / iterate over generated images in terms of those.
