A Brief History of the Internet

" To appreciate the importance the new computer-aided communication can have, one must consider the dynamics of "critical mass," as it applies to cooperation in creative endeavor. Take any problem worthy of the name, and you find only a few people who can contribute effectively to its solution. Those people must be brought into close intellectual partnership so that their ideas can come into contact with one another. But bring these people together physically in one place to form a team, and you have trouble, for the most creative people are often not the best team players, and there are not enough top positions in a single organization to keep them all happy. Let them go their separate ways, and each creates his own empire, large or small, and devotes more time to the role of emperor than to the role of problem solver. The principals still get together at meetings. They still visit one another. But the time scale of their communication stretches out, and the correlations among mental models degenerate between meetings so that it may take a year to do a week’s communicating. There has to be some way of facilitating communication among people without bringing them together in one place. "

The Computer as a Communication Device by J.C.R. Licklider, Robert W. Taylor, Science and Technology, April 1968.

SOCIAL SCIENCE: Computational Social Science

If one were to look at the leading disciplinary journals in economics, sociology, and political science, there would be minimal evidence of an emerging computational social science engaged in quantitative modeling of these new kinds of digital traces.

However, computational social science is occurring, and on a large scale, in places like Google, Yahoo, and the National Security Agency.
