Are you really trying to use failures of AI to try to argue that it's going to overcome humans? If we can't even get it to work how we want it too what makes you think people are just going to hand the keys of Society to it? How is an AI that keeps bursting into racist rants and emotional meltdowns going to take over anything? Does it sound like it is brewing some Master Plan? Why would people hand control to it? That alone shows that it presents all the flaws of a human, like I just pointed out.

Maybe you are too eager to debunk me but you are missing the point to nitpick. It doesn't really matter that we can't "pull the plug" on the internet, if that even was needed, all it takes to stop the AI takeover is that people in power just disregard what it says. It's far more reasonable to assume even those who use AIs wouldn't universally defer to it.

Nevermind that no drastic action is needed period. You said it yourself, Microsoft pulled the plug on their AIs. This idea of omnipresent self-replicating AI is still sci-fi, because AIs have no reason to seek to spread themselves, or ability to do so.
