What will drive people if they don't have money or reward? The reward is the end of war, the end of poverty, most crime, and the end of begging for medical care. Everyone will be cared for and educated. There will be no taxation, and no advantage group. No technical elitism, or any other kind of elitism. If that isn't incentive enough, then I don't know what is.

Learning to be flexible in values takes a very long time...Of course I felt a little uncomfortable during questioning the concept of God, but then reading about the history and evolution of Gods. There were many different Gods: the God of war, the God of peace, the God of love, which was more like the people that invented them. They behaved, they got angry, they made sacrifices, they created floods when they didn't like the way things are going. This didn't come through as superior intelligence.
