The Mother of All Demos, presented by Douglas Engelbart (1968)

Caption notes

In this 1968 demonstration, Douglas Engelbart asks a question about work: what could people do with complex information if a computer were available to respond throughout the day? He uses a shopping list to explain “view control,” showing how a reader can choose how many levels of the same material to see or focus on one part. He also describes how the team left messages in shared files and filtered for messages addressed to them. Near the end, he distinguishes the commands the machine offers from the ways people learn to work with them. His team aimed to design both.
