I just heard someone talk about this and Silicon Valley Billionaires are investing huge sums "Many billions" into living forever or for hundreds of years more. Its kinda scary because this guy who I was hearing also believes that they want to reduce the world wide population.
The idea is to essentially make room for the people living a lot longer if not forever. This is some scary talk they essentially believe that much of the manufacturing and farming will be automated and that the people who do needed but technically limited work will not be needed. That many areas of the world is overpopulated and creating strains on the system and need to reduced if not eliminated.
This guy is not some pie in the sky guy he has a legit background in research and believes many of these goals could happen sooner then people think. Normally I would write this off as some crazy CTer who thinks the government is out to get him. But he pointed out people like Bloomberg, Buffett and many other billionaires have
spent over a billion dollars on setting up health clinics to perform abortions and teach people how to use condoms around the world. He also talked about people like Larry Ellison, Peter Thiel and other powerful technology brokers really believe that this is a goal within reach.
Ok time to take your tinfoil hat off now!

EDIT: I am actually surprised not more people are freaked out about this stuff.
