Ray Kurzweil believes that with the advancement of technology, it is possible for people in their 50s and 60s to live forever. He says that advancements in genetic research and nanotechnology will significantly extend the lives of people in the near future, and by the 2040s technology will have advanced enough for humans to transcend biology. He points out that
processing speed has doubled every 2 years since computers were invented. The CEO of Intel says it will continue well into the 2020s, and by then we will have made significant progress in switching from integrated circuits to
nanotubes. So he thinks this combined with other technological advancements will make it possible to fully integrate the human consciousness with machines.
He makes some pretty cool predictions about how nanotechnology will improve our health... and not just simply curing disease and reversing the aging process, but also making us able to do things that we normally could not do... like hold our breathe underwater for an hour.
