It's a tough one because some ideas may not exist without AI help.
Personally I recently published a white paper on an idea for democracy that has been bouncing around in my head for decades. AI helped flesh out the idea and write the pages of text and structure the whitepaper.
I'm not an academic so I probably would never have fleshed out this idea without AI but I think it's better to have the idea published so it can be seen than to have remained bouncing around in my head until I passed away.
I'd agree that an academic version of my idea written by hand would be better. But a mostly AI written version is better than the knowledge never being published and I still spent a good two days on it making sure I agreed with every paragraph and fixed every issue I could find.
Considering this in general I think the amount of human effort that goes into creating something is probably the right measure of it's quality over if AI was used to assist in it's creation.
