Everyone on earth has heard about the Great Wall of China. That very famous structure was first conceived by Emperor Qin Shi Huang around 220 B.C. to repel the dreaded Hun.
Let’s have a showing of hands here. Please raise your hand of you think Emperor Qin would have started the laborious construction of The Wall if he had the option of using “drones, scanners and sensors to create a technological barrier too high to climb over, too wide to go around and too deep to burrow under” (the words of Rep. Jim Clyburn).
I see only one smallish hand is raised, and it’s in a big white house. Hath his ego no boundary?
