Hawking: A.I. 'worst event in the history of civilization'

I think that A.I. is what is most likely to be the undoing of the human race. It's rather difficult to envisage a way that conscious A.I. could live alongside humanity in a peaceful way without eradicating us, and it's also difficult to envisage how the super rich (who own the robots) could be brought on board with a system whereby their wealth gets transferred to the rest of the (now obsolete) population in order to enable the unemployed (almost the entire human population) to survive.
