You probably think about programs that can create entire artworks automatically. I’d put general feelings about AI and the concerns many artists have regarding it (which also includes boycotting it, due to those concerns),
There are no doubt other creative softwares incorporating AI on windows, but, particularly for linux, there is only one main painting software, Krita, and it’s probably more likely that linux users wouldn’t want AI involved within Krita, with privacy etc being important. There are many time-tested remedies that can fine tune, clean up code, etc … jumping past those things and straight to AI, which is directly linked with being anti-art/artists, and obviously would impact on the future, I don’t feel is useful or morally considered. I’d put general feelings about AI and the concerns many artists have regarding it (which also includes boycotting it, due to those concerns), but, if talking about krita functions more specifically, the projects document containing the quote about not including machine learning also covers about continuing bug fixing, which I understand is one of the most important things for keeping krita running well and as part of any code improvements or additions.
