I feel for me to even have this conversation we need some gradient we can point to and say this is clearly all AI and this is clearly minimally assisted and everyone is along this gradient and past some arbitrary point its no longer aggregable to me.
I use claude in my games(Currently a hobby) I draw a character on paper, claude models the proportions symmetrically and then I go back in and slowly build up the model. I wouldn't have a problem with artists doing this at all, in fact I don't know of a good reason not to. However if they generated a picture, sent that to claude, took whatever claude generated and threw it into the game then its going to look like garbage and cause they didn't start by throwing new information into the system it must start from training data so it will look the same as all the other slop.
That first step of starting with a piece of paper or some human seed is huge, the more detailed that step the less I care about the rest of the process.
