Modern standard is for things to be made cheaper and break easier, not to be more efficient for durability.

Those same people push global warming, climate change, population control, and taking care of the planet. Complete hypocrites and nobody ever brings this up.

That seed vault in Norway is probably the most reliable. Probably the Cheyanne mountain complexes too

Yeah, we have concrete that’s centuries old too. Our crappy concrete buildings from the 60’s and 70’s were all about the dumbshit philosophy of guys like van der Rohe, combined with cheapskate builders and financiers. And the Romans didn’t “engineer” anything. They either discovered their formula through trial and error or blind luck. Probably the former. Some of the speculation about Roman engineering gets as tedious as the assumptions about Nazi engineers and their Vunder Veapons. Roman concrete was so long-lasting not because of any brilliance on their part, but because they had an abundance of volcanic ash to use as a mix thickener, which gave it its water protection properties. They were practical people that would use whatever materials were at hand. They often used rubble from torn down structures as a layer inside concrete to increase thickness. They used the ash because they had a lot of it laying around .

I've never thought they were any less, or any more intelligent than we are today.

of course they were they had the exact same brain. A few thousand years ago is a blink in evolutionary time.

And the roads.

Well of course there's the Roads! I mean that goes without saying.

But apart from the aqueduct, sanitation, the roads,

What have the Romans ever done for us!?

Irrigation, medicine, education.

And the wine.

And the public baths.

And they certainly know how to keep order. Certainly the only ones who could in a place like this.

All right, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a fresh water system, and public health, what have the Romans ever done for us?
