Just a shower thought. Seeing how these structures took decades to build in their times, and that too entirely with manual labour, I was wondering how long these architectural marvels would take to be built in this post modern era with the help of our technological advancements.
Imagine the world has dedicated its focus and the entirety of its resources on building just one Pyramid as quickly as possible out of the same materials and in the same location as the original ones. The medium of construction has no constraints but the end result must be indistinguishable, structure and composition wise.
I would love to hear how the process would take place in addition.
It would be impossible to build today by any means. Not because of any technological problem. Physically it could be done rather quickly, as others have posited. The problem is that you could never combine the political and economic will to complete it.
It’s the same reason it would be easier to colonize Mars than to fix climate change. There’s a half dozen robots on Mars that will do whatever you tell them. On Earth, there’s 7 billion assholes who think they have a better idea of what to do.
