The problem with any system that humans create is that it will be run by humans. Humans care more about gratification, dogmas, or methods, depending on the individual, than they do about ensuring justice or sustainability. When we use the word ‘progress’ we mean either a movement toward what is ‘better’ or what is ‘right.’ No system will bring progress because the component parts, the people, aren’t very different than they were at the start. That is unlikely to change. The future is medieval.
