I don't want even one single grain of sand of the games and assets I support and buy to have ever been touched by any generative AI
If this is about supporting human artists and their craft, very nice of you. Thumbs up.
Unfortunately, there is a high chance for every game engine and library, that it contains code that was made with help of a gen ai.
There is also a high chance for images created by professional digital artists to contain some gen ai pixels. There are photoshop filters that use gen ai for filler and probably filter effects and there are even outright prompt modifications possible.
Meanwhile, actual professional coders and artists use the state of the art tools of their trade. If there are ethical problems by the training set used, those can be overcome. Artists could even train a model exclusivly on their own data. What cannot be overcome is the seemingly unfair advantage of using tech to do what might be done by hand.
One of the best examples in history is usage of photography to do a portrait in seconds, instead of having a painter paint it for days. But from an art perspective, both are different and customers usually notice the difference. And my impression is, that gen ai games are not really popular, and I suspect this is not because of any ethics aspects. As with photography, it is not enough to push a button, you need to be good at using the tech to create good results. In other words: most gen ai games look not really good.
