You may have heard of the Mother of All Demos, especially if you’ve studied, or even read up on, computing history. But have you seen it? There is a video of this legendary event (via Reviewed.com), and I personally find it fascinating. Here’s why this is a thing. The demo was given by Doug Engelbart in 1968, when punch cards were how you interfaced with a computer. But in this demo, the world was shown (list via Wikipedia) windows, hypertext, graphics, efficient navigation and command input, video conferencing word processing, dynamic file linking, revision control, a collaborative real-time editor, and the computer mouse. The freaking computer mouse! None of these things existed outside the circle of people involved in the demo. It was huge. No, it was enormous. And many of the people in the demo went on to be involved in the Xerox PARC, which played a major role inspiring Jef Raskin and Steve Jobs for the Mac. The Mother of All Demos resonated through tech culture for decades, and it took decades to make most of that list above mainstream. If you like tech history, you should book some time to watch this. And if you do, think about the context of the times and be amazed. One last note, the typed story at the beginning explains how the movie itself was made.
