Hmm, when I imagine “Scheming AI that is not easy to shut down with concerted nation-state effort, are attacking you with bioweapons, but are weak enough such that you can bargain/negotiate with them” I can imagine this outcome inspiring a lot more caution relative to many other worlds where control techniques work well but we can’t get any convincing demos/evidence to inspire caution (especially if control techniques inspire overconfidence).
But the ‘is currently working on becoming more powerful’ part of your statement does carry a lot of weight.
My strong downvote just gave +3
