> Can you explain how the superhuman AIs will prevent themselves from being physically disconnected from power?

Three of the common suggestsions in this area are (and they are neither exhaustive nor mutually exclusive):

(1) Propagandizing people to oppose doing this,

(2) Exploiting other systems to distribute itself so that it isn't dependent on a particular well-known facility which it is relatively easy to disconnect, and

(3) If given control of physical capacities intentionally, or able to exploit other (possibly not themselves designed to be AI) systems with such access to gain it, using them to either physically prevent disconnection or to engineer consequences for such disconnection that would raise the price too high.

(Obviously, current AI can't do any of them, at least that has been demonstrated, but current AI is not superhuman AI.)
