They are not useful, sorry. They are vanity professions. All of the anthropologists in the United States could be abducted by aliens from Alpha Centauri tonight and we wouldn’t notice a difference in the morning. If all of the semiconductor professionals disappeared in the same manner we’d have serious problems.

I’ve got nothing against anthropology as a field or anthropologists themselves, but they wouldn’t even show up on the tech tree. You don’t need a PhD to be a school teacher and, frankly, we would be a lot better off if instruction was done by practitioners instead.
