Alienation and resistance to change

IN 1900 the maximum speed of human travel was about 150 km/hour—the express train. This was about 3 times as fast as the maximum speeds of antiquity—a man on a horse. Hence technology, as measured by the speed of travel, advanced three‐fold in, say, 2 000 years. In 1969 the maximum speed is about 30 000 km/hour—the space rocket. Hence the new advance is 200‐fold in 68 years. Within my lifetime the pace of technology is thus about 2 000 times as fast, on average, as during the previous millenium.
