The AI might associate lighter skin with white person facial structure. That kind of correlation would need to be specifically accounted for I'd think, because even with some examples of lighter skinned Asians, the majority of photos of people with light skin will have white person facial structure.

Plus it's becoming more and more apparent that AIs just aren't that good at what they do in general at this point. Yes, they can produce some pretty interesting things, but they seem to be the exception rather than the norm, and in hindsight, a lot of my being impressed with results I've seen so far is that it's some kind of algorithm that is producing that in the first place when the algorithm itself isn't directly related to the output but is a few steps back from that.

I bet for the instances where it does produce good results, it's still actually doing something simpler than what it looks like it's doing.
