I don’t think “AI pessimist” is a good term for what is currently sometimes expressed by “doomer”, because many people are very pessimistic about AI in ways that don’t have anything to do with doom. For instance, I don’t think it would be reasonable to say that Timnit Gebru and Emily Bender are not AI pessimists, but they are savagely critical of the “doom” position and its adherents.
