Arthur Clarke is famous as a science fiction writer, one prominent in my youth. He famously wrote: "Any sufficiently advanced technology is indistinguishable from magic."
That's the third of his three laws.
I think there's a converse to it. J.L. Bell at Boston 1775 notes an article on the importance and complexity of wheels in the colonial era. One of the blogs I follow has posted videos showing someone doing stone age technology; I think this is one of them but I don't remember the source.
Let me play with it: "Any sufficiently out-dated technology seems simple and isn't."
Take the two laws together and modern humans seem advanced and super intelligent.
