This was popularized by Vernor Vinge which is where I recalled reading about it. There are many reasons to celebrate Raymond Kurzweil. In my opinion, his is "work" in nutrition and his near-religion called futurology are not in those reasons. He has become a vocal proponent of a dream to become god-like. I do not share that dream and I wish him the best of luck in his endeavors. I just cringe every time I read of the "singularity being near" or the ability to live forever coming about. If it's going to happen, just sit back and let it happen. I feel he has done a great disservice to the field of artificial intelligence by promising unrealistic things in interviews to the lay person. Disappointment is a sure fire way to get yourself branded as a snake oil salesman religious nut.
What about Max T. O'Connor AKA "Max More"? I thought he was the one responsible for the futurist/transhumanist/singulatiry religion/wishful thinking, not to mention magazines like MONDO 2000, WIRED, and now H+. I never heard of Ray Kurzweil before, but I guess it's mostly because I prefer to read about actual science and not evangelism. My experience with actual virtual reality and other technologies has led me to be somewhat less than hopefull about technologies based on corporate activity. There is an inherent corporate profit-motive that holds back and retards technological progress and affordability at a basic level. Most "extropians", "transhumanists", and such seem to also believe the whole religion is a vindication fro capitalism, which, if we just sit back and dont complain as our bosses order us around, will someday deliver the priomised land.
It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
