I do not think that we are going backwards because every civilization in time and space, from antiquity to the present-day technological civilizations, are all evolving and functioning to the ways and means of contemporary or past societies. I agree with you that there was high culture during the Sumerians. I came across this citation which I am using for my upcoming Hub and it goes like this: "What became of the Black People of Sumer? the traveller asked the old man. "For ancient records show that the people of Sumer were Black(Africans). What happened to them?" "Ah, the old man sighed, they lost their history, so they died." A Sumer Legend. Your question may be on the right track when you ask if we are going backwards, given today's Technological societies and the rule of Technopoly. I have written on various subjects of the issues I am addressing above, and still working towards a comparative historiography, that of Antiquity, and the one of today. I would not readily say that we are are going backward to somewhere, I think we are in a state that maybe we might begin to merge the old and the new, and from that synthetic synergy find the medium with which we might head into the future Historically, and maybe be able to see if one was better than the other, or that the present complemented the Past.. The thing is whether we will use the modern techniques of Media and education to get a 3D view of both the past advances and the present, still infantile technologies, to peak and peer into the past. Because much of the Antiquated history has been lost throughout the millennia, I hope the introduction of the Web will also help in the search for questions we all have about these past civilizations, and some Ivy League University's libraries and others in the local counties and throughout the state and their archives might help with this endeavor. That is my Two Cents.
