I want to mention that I have a wonderful graduate student, Anika Kale, who has been studying intelligence curricula around the world, particularly from the point of view of gender. She finds that there is almost no awareness of gender in there.
You are absolutely right. One source can pollute another source, and there's really no control on that. The best thing to know about this is that AI generally doesn't explain itself. It gives you an answer. My big objection to ChatCPT is that it makes that answer look very authoritative when it's making it up out of nowhere. I got it to write a poem once, and it put a disclaimer at the bottom that I thought was very interesting. It said that this was a creative work and it didn't really have any facts in it.
You are absolutely right. One data source can poison another data source. I have no doubt that intelligence agencies around the world are busy trying to poison our wells of open-source data right now.
