Therein lies the problem with some. Human history has always had those that see there own generation and time, as the epitome of progress. I bet even some in the old Roman Empire also thought their achievements were state of the art, never to be surpassed. It appears to be a trait throughout human history, and sometimes even attributed to otherwise great men. I see it as an ego driven geo-centric malady from the days when we thought the Earth/Sun/MW galaxy was the center of creation. But we know differently now.
