To be clear: that is not what Cory is doing. He just said he knows some people who are using a tool successfully, which is a fine argument on its own. But my counterargument is "there's lots of *evidence* out in the world that other very smart people have thought they were doing fine but were actually doing badly with this tech, I don't think Cory's friends are special". If you're rebutting that with "but they are specific people, maybe they *are* special!" I think you're falling into that trap
