1) I think this is trying to solve a non-existant problem. You are making it sound like all major graphics compo's are infested with dishonest wiring lowlives stealing all trophies away.
4) We can trust our fellow sceners to do the right thing, there has been no cheating in major compos in recent years.
Also workstages prove nothing, since they can be easily faked! That point is often overlooked.
How to get over it? We can train our own models and in my opinion and that is when AI art will become "original" and "personalized". It'll be a tool like a brush, and we can train the models with our own drawings or music and it'll generate stuff within that context. Is this better? I do not know. It just will be. Some great artists had assistants that took care of the details after they set up the sketch and broad strokes. Perhaps the AI can be like assistant to an architect or a sculptor.
Well, we do not have to, but it'll happen any way. LLM's are at a moment SISO systems like all computer expert systems. Shit In, Shit Out. Unless they've been shown what pre-Amiga 80's brutalism is as an art style, they can't do stuff like it.
