It's not just historical. I'm a white male and I prompted Gemini to create images for me if a middle aged white man building a Lego set etc. Only one image was a white male and two of the others wrecan Indian and a Black male. Why when I asked for a white male. It was an image I wanted to share to my family. Why would Gemini go off the prompt? I did not ask for diversity, nor was it expected for that purpose, and I got no other options for images which I could consider so it was a fail.
