I recently learned about a computer demonstration dubbed “The Mother of All Demos” given 40 years ago by Douglas Engelbart at the Fall Joint Computer Conference in San Francisco. Douglas showed off the NLS computer to a crowd of 1000 computer pros. The demo of this system given on December 9, 1968 is now considered one of the most important in modern computing history.
