Ray Kurzweil talks about the speed at which technology has advance throughout history and most importantly the rate at which it has evolved in the last decade as well as where technological advances are headed in the future. Kurzweil believes that the speed at which technology is growing suggests that we will be able to use technology to our own capabilities that will forever blur the lines between human and machine. He suggests that by the 2020's we will have reverse-engineered the human brain, and nanobots will be operating the human conciousness.
He begins his talk by explaining how accelerated power has begun to transformed us and how this accelerated technology is more predictable than one might think. Communicative technology for example has exploded within the last decade and continues to accelerate at a rapid pace.
