So I did not read the article because of a paywall I’m too lazy to circumvent right now

But from OP’s summary, the main technology they’re talking about concrete reinforced with steel or other fibers.

And that’s definitely more advanced than “pyramid age”

But it’s also pretty much a direct descendant of mud brick reinforced with straw which humanity has been using since well before the pyramids. Same basic concept, different materials.

So yes and no.
