What are the achievements of the time period of 1000-1300 really medieval and uncivilized?

I feel that the achievements of the 1000-1300s were medieval, not uncivilized. The achievements and things they knew can from the technology and the information they knew. The technology was rather primitive which limited their accuracy on facts and sciences, it also limited what they could discover to what they could see, hear, touch and get to. Today technology is vast, it let's us do everything and anything, also communication with the rest of the world was limited to the information and achievements were isolated to those regions. ALthough the achievement would later be trumped by our generation, the achievements they did have were based on a lot more brains and hard work rather than today's computers and technology.
