How humans will lose control of artificial intelligence

This is the way the world ends: not with a bang, but with a paper clip. In this scenario, the designers of the world's first artificial superintelligence need a way to test their creation. So they program it to do something simple and non-threatening: make paper clips. They set it in motion and wait for the results -- not knowing they've already doomed us all. Before we get into the details of this galaxy-destroying blunder, it's worth looking at what superintelligent A.I. actually is, and when we might expect it.
