Between this and the proposal of nanobot technology being available within the next 20-30 years, it looks like were going to give rise grandchildren that are half human-half robot... No but really though, its a pretty interesting read so you should check it out. And for anyone who doesn't know what nanobot technology is, check out my previous thread about a documentary called Transcendent Man. I also posted the link to a video in there where a group of doctors successfully implanted artificially made hearts into a bunch of animals and even a man. All of who were still alive after surgery. Anyway, here's the link to the article.
