We tried it in class, after hearing about the US founding fathers being black and Nazis being surprisingly diverse with Asian women in the ranks too. Finnish Medieval couple was a black guy with an Asian wife. Maybe the AI was thinking of Netflix version of Finnish history.
Actually its understandable what happened. All the image generators are well.....white as fuck yo. go hit up bing and put in a prompt that doesn't mention race and hit return like 30 times. You will get maybe like 3 people who aren't white. Google wanted to fix that so they taught it to put in various diversity keywords when given prompts. The issue is it was NOT content aware.
