What’s the greatest single human artifact in the world?
At different points in history I think my answer would probably be objects like the Pyramids of Egypt, the Great Wall, the Suez Canal, or the Hoover Dam.
Nowadays, though, it’s not even an object, exactly. I can’t think of anything that tops the Google database.
Well, I can only say that I just couldn’t agree any more entirely with you.
