I think there is the issue of what satisfies humans? Not only will this change with time but everyone wants something different and in many cases something that makes one person happy directly makes another unhappy. Instead of having the AI try and make humans happy or satisfied it should instead be used to ensure the survival of our species.
There are many ways the human species can die off. A simple asteroid hitting earth, the sun's inevitable death, there might even be another intelligent species that made an AI that decided to turn the entire universe into paperclips or whatever it is they use to hold their documents together. The point being as happy as the AI could make us there will be no one to make happy if humans are all dead.
There are infinite ways you can try and tell the AI to follow rules but all it takes is one exception or bug and you have a big problem. Any true AI we create would be able to create increasingly intelligent versions of itself and would quickly outstrip the combined intelligence of every human on this planet. 64
One of our first rules in that case should be for the AI to minimize its size and used resources while maximizing its intelligence and awareness of the universe. This would atleast prevent the AI from simply expanding as fast as possible to increase its intelligence and result in the smallest impact on the universe as it does expand.
While the AI is increasing its knowledge and awareness of the universe it should use this to indirectly protect and preserve the human species. We do not want the AI to become apart of our everyday lives. Unless we can teach a machine what it is to be human and then agree upon its conclusions it would not be safe to try and have it maximize any sort of happiness for us, the chances of us all ending up in some sort of virtual fantasy land or drugged out of our minds to "optimize" happiness is just not worth the risk.
What we want in the end is an AI that we hardly know exists. It prevents extinction and lets humans continue to be Human. I for one prefer the Red Pill. 64
