How can you explain the fact that we are living in the most peaceful time in the human history? Surely we are not able to change the human mind to control the desires of wanting more and more but we have definitely improved the fundamental definition of what it means to be human. We are not barbarians anymore, we don't enslave other human being for fun and profit anymore. These things matter and matter a lot. We are still in the development stage in-terms of society. We still treat people differently depending upon their skills, knowledge, power and still have notion of national borders and military to protect those borders. I have a feeling that technology will take us to the level of such abundance that future generations will find it hard to believe that we killed each other for resources and honored artificial geological boundaries.
