I feel as though morally dubious is extreme. it doesn't hurt original creators any more due to recent copyright rulings in the supreme court. and using this art will never be similar to original artists, there will always be defects. but because of the nature of the game jam, we needed a larger amount of scenes with cohesive styles, using an AI generated pack helped in making a good vertical slice of a game. I personally wouldn't normally use AI art in well developed projects with more time involved.
