I started reading Ivan Sutherland’s thesis for Sketchpad from 1963. Sketch pad is generally considered the first extensive interactive drawing program. I wanted to share an excerpt from the introduction.
Heretofore, most interaction between men and computers has been slowed down by the need to reduce all communication to written statements that can be typed; in the past, we have been writing letters rather than conferring with our computers. For many types of communication, such as describing the shape of a mechanical part or the connections of an electrical circuit, typed statements can prove cumbersome. The sketchpad system, by eliminating typed statements (except for legends) in favor of line drawings, opens up a new area of man-machine communication.
Pretty amazing that he was able to see the graphical potential of computers over 40 years ago!
