The Da vinci robot reminds me of normal suits of armor, presented to us as Knights from the medieval/dark ages that are absolutely and completely impractical at all for humans to wear. If you actually look at most of them, and REALLY look, a modern day human couldn't fit in most of them at all, especially not if they planned to walk, ride, or fight in them. Combine that with the questions about architecture of castles, reports that most 'Knights' and lords who were known to wear them were ever seen without their armor and/or their helmets .....
Are we being presented with a cover-up for a wide-scale existence of robots that were used all across the world for .. well, look at the missing materials, transportation of said materials, MAN POWER to construct all of these buildings. Did we (humanity) actually have robots working tirelessly? Did we actually come from some sort of utopia-type civilization that the last reset obliterated to the point it became unrecognizable?
Fallout 4, based in Boston, has Diamond City as one of the first bastions of still living civilization 200 years after the nuclear event that destroyed the world. Listen to this character describe Baseball, and how it was played, based on the items they found in the park when they started trying to rebuild.
Baseball, 200 years later
Does the distortion sound remotely similar?
