Picture an everyday scene. You’re in a high street coffee shop. All around you people are drinking coffee. Some people are chatting with friends and others are using their mobile phones. In a corner of the coffee shop an internet café has been set up. At one table a couple of teenagers are laughing at a message in a chat room, while at another table an old man searches the Web for something.
Now imagine this scene through the eyes of a technologist from 100 years ago. This is someone who has thought carefully about how technology and society might develop during the twentieth century.
Surprising may be the realization that some of the people here are working in an easy way. Most surprising perhaps will be the technological tools most people seem to be using. The technologist is aware of the telephone, which was invented about 30 years earlier. But most of these twenty-first century people seem to have wireless pocket-size personal communicators they can use to send messages or speak to anyone anywhere in the world.
Some are using a handheld machine that contains thousands of pieces of information that can be accessed instantly, and can do calculations in a fraction of a second that would have taken a team of operators with mechanical calculators hours or even days. And these machines, like the only slightly larger versions in the corner, can be connected to a global brain from which the people can call up almost any information, news, idea, opinion or gossip that exists anywhere on the planet.
Most of the changes in technology, compared to 100 years ago, are due to the continual inventive activity of a large number of people. Most of us don’t do anything other than maybe form a vague idea about how a product or process might be improved. In some people, however, this inventive drive is so strong that they act on it.
