I provide herein a quote:
This was no run-of-the-mill boring-vision-of-the-future demo. This was, simply put, “The Mother of All Demos”. Steven Levy first gave it that name and it seems to have stuck: The Mother of All Demos (and oh I really love that name). Douglas Engelbart‘s whirling vision of the future; it was the first public use of a mouse, as well as examples of cutting, copying, pasting, teleconferencing, video conferencing, email, and… hypertext. It’s just too damn much for 1968!
You can see the demo here. It’s truly incredible.
