- In the early 1960s, Douglas Engelbart started investigating how computers could augment human intelligence: “If, in your office, you as an intellectual worker were supplied with a computer display backed up by a computer that was alive for you all day and was instantly responsive to every action you had, how much value could you derive from that?” Engelbart developed many features of modern computing that we now take for granted: the mouse,1 hypertext, shared documents, windows, and a graphical user interface. At the 1968 Joint Computer Conference, Engelbart demonstrated these innovations in a groundbreaking presentation, now known as “The Mother of All Demos.”
