It s not X, it s Y.That is so a genre or idiom of the current AI age. Why? I think because AIs live in language. They don t live somewhere else. So they have to exclude all the language network of things it s not in order to focus themselves on the thing it is. If they were more subconscious/symbolic like us, they could just not say that. But because their words, create their words, etc - more than us - they have to use this construction, to exclude the gigantic amount of stuff that whatever you re talking about is not.What do y all think?
