> Say I make a video and for some reason use genAI to depict nationalities. It has to be a single person so I can't have it generate a group photo of all of Nigeria's 300 ethnic groups, so how do you display diversity in a picture of a single person?
In a sense, you can't display diversity in a picture of a single person, unless you want the AI model to produce "a person with characteristics of many Nigerian subgroups" rather than "a single Nigerian person" in response to the prompt "a Nigerian". Would it be a significant problem to the purpose of your video to show a member of a particular ethnic group and explain that it was a coincidence if someone asks about it? Additionally, if you really want to represent 300 ethnic groups in a single image, then you might still get complaints from people who won't recognize their minority group in an image of "generic Nigerian", which I'm interpreting in your case as "a person with characteristics of 300 Nigerian ethnic groups".
> Now if my video happens to be the one to blow up on the internet for some reason then the rest of the country probably won't be happy that that specific group was used to represent them as a whole.
> In that sense using the stereotype is the fairest way since everyone is equally misrepresented.
This idea of "fairness" is problematic in my opinion. I would not want to be in your position if something like this were to happen to you. However, pleasing many ethnic groups by generating an approximation of an entirely fantastical "person who represents 300 ethnic groups" (the relevant alternative being an approximation of a more realistic "person who represents 1 ethnic group") isn't fair to you. You shouldn't be at fault if Nigerian viewers jump to conclusions about whether you are favoring a specific minority group. You shouldn't be at fault if non-Nigerian viewers unfamiliar with multiple Nigerian ethnic groups take the image you used as representative of "Nigerian" as a whole.
Disclaimer: I'm not even slightly familiar with the social relations between Nigerian social groups. If certain Nigerian groups think of each other with dehumanizing hostility the way some Han Chinese people think of Uyghur Chinese people, then I apologize for being insensitive.
