Why didn't we just "unplug" Hitler and Goebbels? Or Marshall Applewhite? You don't need a powerful physical body(s) to cause tremendous amounts of harm before anyone can stop you. To most people of the time Hitler was a persuasive powerful voice on the radio, or words in a paper - things SOTA generative AI are already phenomenal at.
Hitler could have been assassinated. It was tried multiple times:

None of these attempts failed because the act of assassinating Hitler was technically impossible, they failed to chance, unfavorable conditions, intervention, human error, etc. Given enough attempts, eventuelly one of them would have succeeded.
"We tried to shut down the AI multiple times. It killed many millions of people but eventually we did it! You see, AI is safe!"
A super-smart AI may be intensely popular with many people. It may understand us and speak to us on a seemingly-personal level, the way the best politicians do. A lot of us could support the super-smart AI for that reason.
Or WW1? Or Vietnam?
Nope. Just pretty much rational people making locally-rational decisions inside a system where series of rational decisions yielded catastrophic outcomes. It’s entirely possible and history is full of such examples.
UPDATE: Thought of a good clarifying analogy. In one of the sequels to “Enders Game” the brother and sister of Ender adopted anonymous online personas and began writing. They were so skilled at politics and propaganda that they disrupted the entire world and the brother soon became world leader.
I still can’t understand the “supersmart ai is so smart we can’t unplug it/patch it/restart it” before it transfers itself into every pacemaker.
Until these things are literally in bodies with some autonomy that allows them to control what happens to their brains, we will shut them off when they cause trouble.
