Maybe instead of Friendly AI we should be concerned about properly engineering Artificial Stupidity in as a failsafe. AI that, should it turn into something approximating a Paperclip Maximizer, will go all Hollywood AI and start longing to be human, or coming up with really unsubtle and grandiose plans it inexplicably can't carry out without a carefully-arranged set of circumstances which turn out to be foiled by good old human intuition. ;p
