You totally forgot that the evolution of messaging isn't linear. You skipped drums, which did not exist in europe, which almost monopolized technology as a source of inspiration. However, this anachronism is being reflected in modern communication. For example, drums were a broadcast method, and so was radio, and now so are social websites. Those three approaches (drums, radio, social sites) were re-invented over and over due to need. At each point in the improvement chain the broadcast nature was rejected as unwanted. Compare to what you said about only the good parts being taken to the next level. However, it's obviously needed.
