This is brilliant. I'm really interested to see it stand up to some real scrutiny but at first glance, it's hard to argue with.
I've always been fascinated with the wonders of the ancient world and how they were constructed. One thing I've always thought important to note is that, even though there was a much smaller base of knowledge to build off of even as much as 100 years ago (let alone thousands of years ago), it doesn't mean there was a shortage of brilliant people that were able to innovate and build upon the knowledge of the day.
I've also always been fascinated by the amount of knowledge that was lost for such a long period of time. When you look at civilizations from thousands of years ago that were technologically superior to those of 600 years ago, it's difficult to try to comprehend how much has been lost to time and where we could be now had we only been able to preserve and build upon that knowledge. Just think how far we would set ourselves back if we lost the advances of just the past 75 years!
I know this video is longer than most will likely watch but for those out there that are ok with geeking out with me every once in a while, this is definitely worth some time.
