All of the AI uses I've listed have been around for almost a decade or more and are the only computational solutions to those problems. If you've ever used speech to text that wasn't a speak-n-spell you were using a very basic AI model. If you ever scanned a document and had the text be recognized, that's an AI model.
The catch here is I'm not talking about chatgpt or anything trying be very "general". These are all highly specialized ai models that serve a very specific function.
I did not mean proper balkanization with interstate wars. Just breaking up the US as OP suggested.
Regardless, the idea that the US's imperialism has brought peace to the world is deeply unserious. As well is your notion that China would be the new global aggressor. At worst it would be the regional hegemon that it has historically been. Israel and the UAE have been far more aggressive than that and with the US's backing.
