Arguably letting a big weight fall down after being brought into the air somehow is also pyramid age tech.

Basically they used egyptian age tech to outplay billions of dollars worth of weapons tech.

These bombs are not just dead weights. These bunker busters are equipped with precision guidance and fly to and hit a person on the head if they desired. It’s also designed to deliver a huge explosion AFTER it penetrates with the kinetic impact.
It can also be set to explode right before impact, like Israel really likes to do when attaching residential high-rises, to deliver maximum destruction and death.

Hardly. Did you read the article?

Fiber reinforcment is thousands of years old.

Calling that pyramid age I think is a little disingenuous, they didn’t have 40,000 psi concrete back in those days.

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.

Yes…no…maybe? I don’t know. Can you repeat the question?

Egyptians stacked blocks of stone to build the pyramids.
Roman concrete was impressively strong.
Neither of them had steel-reinforced concrete.
Neither did Gothic cathedrals, which is why they needed flying buttresses.
Reinforced concrete as we know it today is a 19th century innovation, as I understand it.

Maybe the commenter was thinking of adobe.

And this tech goes way beyond merely “reinforced”.
