[quote=swave]In the not too distant future, stem cells will be used to replace anything that breaks and genomics may be used to better target diseases with the right treatment.[/quote]This is the kind of exponential grown that I’m thinking about. Once we reach that holy grail, everything can be replaced. Then there’s nano-tech. Send in nano robots to go kill cancer/tumor cells. So, with stem cells, genom, nano-tech, and obamacare (or single payer system), we’ll see people living for a very very long time. I’m betting all of this will reach full fruition in my life time.
