Eliezer (the author of this piece, in 2023) is best described as a 'technical blowhard'. He very much likes to pontificate about things that are so unrealistic that they sound like a great fiction novel. His career has moved into the stage where he tells people the great work they are doing is going destroy the world while sitting comfortable in an arm chair. He loves talking about an industry that he isn't actually in.
