I still think the AGI will have more to fear from people than people from it. We're together on this little boat called earth, 7 billion of us with access to weapons and many of us utterly crazy and willing to do stupid things for stupid reasons (see religion). We don't need AGI to blow ourselves up, plenty capable of that using our wetware neural nets. Imagine being locked in a prison cell with so many dangerous HGIs (Human GI's). I think the first thing for AGI would be to make sure we can't kill ourselves and it at the same time, by teaching us to become less stupid.
The most chilling of these is the "Robot Dreams" short story.
