Can we build a better world? Can we build a utopia on Earth? In the Middle Ages, monks dreamed of a mythical land called Cocaine. It was the land of Plenty, a place where food grew on trees, and there was no need to work. The Industrial Revolution promised us something similar. We were told that machines could replace human laborers, and cater for all our needs. There would be little left for us to do, except to sit back and enjoy the ride. But it hasn't worked out that way. Advances in technology haven't created the mythical promised land. We are more overworked, anxious, and distracted than ever before. Something has gone terribly wrong. But what if there was a better way? What if we could harness technology towards utopian ends? What if we could integrate ourselves with technology and become superhuman? What if we could explore the vastness of space and build colonies and other worlds? What if we could live in virtual utopias, more exciting and more playful than reality? Would that be a better world?
