We are undergoing a tremendous social change. Everything people take for granted is changing rapidly. This is because information flow is increasing faster than at any other time in history. I have some favorite figures I like to quote in that connection from the French statistician Georges Anderla, who says information doubled between the time of Christ and Leonardo; that's 1500 years. It doubled again between Leonardo and the steam engine, 250 years; doubled between the steam en­gine and quantum theory, 150 years; doubled between 1900 and 1950, that's 50 years. And he concluded his study in the '70s; it had doubled between '68 and '73, that was five years. Jacques Vallee recently calculated that it's doubling every eighteen months.
