Many credit the proliferation of the personal computer down to the GUI but I credit Englebart's mouse , without it the GUI would have lacked mass appeal. It was the two button remote control. It's now being replaced in many instances by the finger but without the invention of the mouse I suspect we would still be waiting for touch.

The fact that he was also the father of video conferencing shows that some ideas from brilliant minds take a little bit longer to reach mass adoption.
