Will the 3,280 foot Kingdom Tower in Saudi Arabia ever get built? Who cares! I can tell you that even if it does, it won't still be standing in a millennium. I think the Egyptian Pharaohs had the right idea with their pyramids. Nothing is as stable as a huge pile of rocks.
If I had a few billion dollars to waste, I'd build a pyramid several times larger than the Great Pyramid and designed to last forever. I'd put it someplace geologically stable and high above sea level. Let's see who's laughing in 10,000 years! Me.
