It seems to me that the majority of us gamers are pretty sensitive about seeing AI-generated art in games. It seems that adding AI-generated art into your game is practically killing it before it was born.
I wouldn't know. I haven't researched that aspect of it. The games I play, are because they're original and fun - the graphics are neither here nor there.
Think of it this way: If I'm stuck on a piece of code for C#, I ask Bing (search engine), and Bing tells me exactly how to code it. It saves me hours of trying to figure how to program one small part of a script. Why now would I draw a line and deny graphic artists the same shortcut? And if I hired a graphic artist, how would I know whether or not they used AI to produce the graphics?
Same with translators: They now run their text through software that auto-translates it. They only need to edit it. Is the result of their labour worth less because they had help? Nobody has vilified translation software (which most likely was also trained on "stolen" works).
(The one or two fully AI Generated games I tried to play failed dismally because so many aspects of the game was missing. I found the games unplayable and not fun.)
