I like the ending words: > History shows that such progress is unnatural, and typically dies quickly. I once was reading a piece of fiction where, at some time in the future, progress had stopped entirely and was regressing, even if there hadn't been any big conflagration and it was due entirely to a change in culture. One of the reviewers of the piece of fiction said that "such a thing is impossible, people always push for progress". I'm not sure even of that, that people always push for progress, but I know for a fact that progress requires lots of coordinated work and social support, and is all too easy to stop. If you have any doubts, look at most nations on Earth; look at Cuba for example.
