Also, I don't think a PHD of Industrial Sociology is really a job anyone needs to have done, so it's unlikely anyone will bother training an AI to do it. That doesn't mean I think studying Industrial Sociology is worthless, I just think it's unlikely anyone will fund training an AI to do it. Besides, is that even how AI's are trained? By some professor somewhere teaching them how to do his/her job before being replaced? That's like how it worked in Player Piano by Vonnegut, but it's not how they actually work.
