Human tool-makers always make tools that will help us get what we want, and what we want hasn't changed for thousands of years because as far as we can tell the human template hasn't changed either. We still want the purse that will always be filled with gold, and the Fountain of Youth. We want the table that will cover itself with delicious food whenever we say the word, and that will be cleaned up afterwards by invisible servants. We want the Seven-League Boots so we can travel very quickly, and the Hat of Darkness so we can snoop on other people without being seen. We want the weapon that will never miss, and the castle that will keep us safe. We want excitement and adventure; we want routine and security. We want to have a large number of sexually attractive partners, and we also want those we love to love us in return, and be utterly faithful to us. We want cute, smart children who will treat us with the respect we deserve. We want to be surrounded by music, and by ravishing scents and attractive visual objects. We don't want to be too hot or too cold. We want to dance. We want to speak with the animals. We want to be envied. We want to be immortal. We want to be gods.But in addition, we want wisdom and justice. We want hope. We want to be good.
