Artificial Intelligence: a five-point plan to stop the Terminators taking over

Lots of work is going into the apparently simple, but in fact complex, field of turning things off. As soon as you give any machine a goal, even as innocent as making daisy chains, you give it the subsidiary goal of staying alive, because it cannot make daisy chains if it has been turned off. So any reasonably intelligent system will seek a method to disable the off button. It is the hardest technical challenge AI fans face. But there is no answer yet.
