Strong AI is not necessarily a bad thing. Instead of worrying about questions 1 & 2, we could be thinking less about constraint and competition with AI and more about cooperation and goal-orientation: e.g. the work of Yudkowsky (https://intelligence.org/files/CFAI.pdf) or some of the thoughts provided by Nick Bostrom http://nickbostrom.com/. Goal-orientation is preferable to capability constraint because the potential benefits are far larger.

Tl;dr: I, for one, welcome our robot overlords (so long as they don't behave like our robot overlords).
