This is exactly right. There's a great piece of fiction called "The Metamorphosis of Prime Intellect" which posits a hyperintelligent AI taking control - and the critical bit of power which the AI acquires, to make this come about?
It gains the ability to teleport ANYTHING, ANYWHERE. It literally can create whatever it wants. Without something pretty close to that being available - I'm really not too worried about hyperintelligent AIs.
