Jon Udell, Who would need a telephone?: To demonstrate the new technology, Moore said, the evangelists would unspool some copper wire, stretch it across the stage, connect two phones, and show how two people could talk to one another over the wire. But nobody got it. Any fool could plainly see that those two people could as easily shout across the stage to one another! Who would need a telephone? They didn’t get that the wire could also stretch across continents and oceans!

Wonderful!
