Sit a UI designer and an engineer down for a couple of sessions to talk about a touch screen (x,y coordinates coming into software from human hands) anytime in the last fifty years and they will come up with the concept of gestures in at most a few hours. What about Douglas Engelbart's work or the work at Xerox in relation to Apple's later ridiculous attempts to claim the windowed GUI as their own?
You accuse others of making up facts but you are ignorant of quite a few.
