I would say the issue is a bit more Complex(TM).

In one case, if I use a generally available program like Stable Diffusion with a generally available model and generate images with it, should I be able to copyright the product because of the combination of prompts and configuration that I used? I am not definitive on this but I am leaning towards no.

On the other hand, if an organization uses a proprietary algorithm, trains a model on its using using stolen art, etc., they would have a more of a case of copyright in my opinion. My gut says "no" for a variety of reasons but there is more of a case.

Tldr: abolish copyright
