Talk overview
dartmouth time sharing 1964
Dartmouth Time Sharing, 1964

“The primary goal motivating our development of DTSS was the conviction that knowledge about computers and computing must become an essential part of a liberal education.”

Kemeny, John G., and Kurtz, T. E., "Dartmouth Time Sharing, “Science, Vol 162, No 3850, October 11, 1968, pp 223-228.

Skills and concepts

“The average college graduate of today is almost sure to need a computer in his work twenty years from now. Therefore, we must prepare him today to use this most powerful of tools”.

“Even more significant is the need for changing the attitude of the typical intelligent person towards computers. ...It is vitally important that the leaders of government, industry and education should know both the potential and limitations of the use of computers, and to be aware of the respective roles of Man and machine in the partnership”.

John G. kemeney and Thomas E. Kurtz, “The Dartmouth Time-Sharing Computing System,” Final Report to the NSF), June 1967.

cringely quote
Cringely quote

We've reached the point in our (disparate) cultural adaptation to computing and communication technology that the younger technical generations are so empowered they are impatient and ready to jettison institutions most of the rest of us tend to think of as essential, central, even immortal. They are ready to dump our schools. (my emphasis)

R. Cringley, War of the Worlds: The Human Side of Moore's Law, March 21, 2008,
