@conradmonson30 I'm not a Shapiro enthusiast. We don't make things to last 100 years. Ever heard of Roman concrete? Lasts more than our modern concrete. The problem is, you can't use rebar to reinforce it. So you're limited to construction that keeps each segment in compression rather than tension, that's arches and domes. Modern concrete construction techniques are so much stronger you can make flat slabs, you can make the segments much lighter, and you can make stuff much taller without requiring massive support arches. But it's not going to last 2000 years. The cracks and corrosion will eventually require the building to be brought down and something else rebuilt.
We always talk about how old cars were bullet proof. Well, if we made cars overbuilt the way they were, we wouldn't be able to afford them. When my parents were kids, the average person couldn't own a car where I live. Now in average the families living there have like 1.5 cars.
What does it all mean? Anyone can pay lip service to what happens 100 years from now. Truth is, everyone can lie about it because few expect to still be around then. When you make it about the practical, what happens to X when Y, you kind of give up the big picture. You want the big picture? It doesn't matter what happens after 100 years if that house isn't going to be there anymore. Because it was never built to last 100 years.
