CAMBRIDGE – It is frequently said that we are experiencing an information revolution. But what does that mean, and where is the revolution taking us?

Information revolutions are not new. In 1439, Johannes Gutenberg’s printing press launched the era of mass communication. Our current revolution, which began in Silicon Valley in the 1960s, is bound up with Moore’s Law: the number of transistors on a computer chip doubles every couple of years.
