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.
If anyone wants to understand the pain of fissile uranium production, play factorio. Gives you a little tiny fraction of what it’s like to produce enough fuel for a powerplant. You need a lot more for a bomb.
