Your calculations are off because you don't realize that while a lot of servants are enjoying their life in the castle, it's been built for the royal family and its court.
It doesn't match the artistic quality and cultural significance of st sophia or the pyramids, not even close. It's just a big glass and steel office space surrounded by a park. Sure the shape is not common, it's gonna have a few high-tech gimmicks and it carries the whole "apple" aesthetic, but it's rather blunt and feels generic (at least for me). Don't get me wrong, it's still a great project for what it is, just not the kind of project that you can call a monument a couple of centuries later
That's what you think of it. But again, it's not been building for you. It's been built for the rich people at the top of Apple. It's massive. It's designed like an apple product. It fits their purpose of symbolism, the success of design and money, a place to put all their collections of brains for show.
What you think of it, your taste, or any feeling you can have about it is completely insignificant to them. They have the exactly the pony they want. It represents exactly what they want it to, like said monument represented exactly what the people that paid for it wanted it to.
now pyramids at the time of construction were massive engineering, this is just dumb boring building
