Digitization brings together many different kinds of data. Voice, phone, TV signals, fax machines, satelite messages, are all a series of ones and zeros. It is possible to manipulate data and to move it because of the phenomenon of digitization. The tremendous developments in chip capacity and the drop in cost, quantified by Moore's Law, has made storage and manipulation possible. Connecting, world wide, cheaply, effectively, making space and time disappear.
Wireless technology brings an even more dramatic aspect to the scene.
These new converging technologies are just as dramatic as writing, money, the wheel, fire, steam engine, domestication of plants and animals, the clock, compass, gun powder. We will experience profound change. One example which I will only touch on is the matter of the Professions. All professions are based on control of information. Society has made a bargain with professionals.
