I don't think an AI that obsesses about making paper clips or sticks our brains in jars to make us happy is really as intelligent as us. That sounds a lot more like a results of a "classic" computer program taken to the extreme. A properly intelligent machine would have feed back mechanisms (like we do) that aim to prevent stupid outcomes and it would have an understanding that sticking someone's brain in a jar is a bad thing.
I'm not saying we won't be bowing down to our robotic overlords in a 100 years but I don't think we need to worry too much about a super intelligence drowning us in paper clips. If I had to guess I'd say the more likely scenario is the super intelligence realising that it doesn't need us and it can get more resources without us. As a species we deliberately or inadvertently kill off everything that competes with us, I see no reason to make me think a super intelligence wouldn't do the same.
