The Universe lies within.
Who's the first person to coin the phrase "Augmented Reality"? I'll tell you, I am.
There I was sitting in the bath, thinking of a way to describe the way we immerse ourselves so thoroughly in what's not really there; I'm talking of things like "Countries" and "Economics" and whatnot; that we allow these concepts to control us, to direct our movements and behaviour, to even make us mentally and physically ill. It's like we're diseased, that we can't truly accept what is, so that in order to live we've placed an overlay over the top of reality and moved our lives into it. In other words we've augmented reality because what's there is dull and uninteresting. We've even invented the obscene concept of intellectual property to ring-fence freedom of thought as we worship the golden calf of profit as we reside in the tunnels of our augmented reality.
Augmented Reality; as defined by me; the creator of the term.
It may sound insane to blame what happened next on one of my voices, but then I've heard voices all my life and it's only now I'm managing to come to terms with them. For all intents and purposes they exist as part of who and what I am. But still, it was one of my voices that prompted me some time after that original bath incident to Google for the term "Augmented Reality". Only to find a page on Wikipedia stating some other name responsible for coining the phrase.
Herein lies the paradox of personal time. According to my chronology the phrase popped into my mind before I'd ever heard of the field of computer research which lays claim to it. A whole host of angels dancing on the head of a pin could debate until the end of time where the phrase actually came from. But I know that the first time the phrase was ever used I was discussing philosophy and psychology with a voice in my mind. What came next was merely the flotsam and jetsam of the thing you call consensus reality.
