No- -one will ever one will ever… …. . No "The Americans have need of the telephone, but we do not. We have plenty of messenger boys.“ -- Sir William Preece, chief engineer of the British Post Office, 1876 "I think there is a world market for maybe five computers." -- Thomas Watson, Chairman of IBM, 1943 "There is no reason anyone would want a computer in their home." -- Ken Olson, president and founder of Digital Equipment Corp., 1977 "But what...is it good for?“ -- Engineer at the Advanced Computing Systems Division of IBM, 1968, commenting on the microchip
