I would assume that the computer systems in China that control nuclear missiles, as well as our computer systems that control nuclear missiles, are air gapped and therefore not hackable no matter how smart the AI is.

This only demonstrates imposed limits you are able to imagine, not what’s possible in all scenarios. A super intelligent AI can bribe, social engineer and do anything it wants. No system is foolproof.

Well yes in an imaginary world everything is possible. We are less close to what you’re describing than to having flying cars.

Gotta love the bot accounts here
