I can't understand how people can keep shouting "it's not AI, it's not really thinking" and then go and label a bunch of numerical weights to be "racist".
On the other hand I'd be happy calling, laws, customs, organizations, religious beliefs, and various other things and conclusions drawn from statistics 'racist' without them being living, thinking beings.
First, although "AI exhibits racial bias due to biased training data" is far more accurate, I think it's perfectly acceptable to condense that to "AI is racist". Especially in the headline of an article that goes on to explain the issue in detail.
Second, I would say that even racist humans are racist because of bad training data, so if we're fine calling people racist, why not AI?
