Leiner et al. (2003)
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.
