The recent discovery of Homo naledi in 2013 led to paradigm-shifting revelations. It suggests that the ancient Australopithecus could have also had at least some of the social or organizational skills attributed to more recent species of humans. How did we, Homo sapiens, not only survive, but also climb our way to the top of the food chain while other hominins went extinct?

Eventually, some people will find a way to exploit this technology either for wealth, image, status, or success. If this could eventually lead to longer lives, there would certainly be people with disposable wealth willing to pay any price for immortality. Of course, we may be years away from this becoming a real issue. At least, I certainly hope so.
