This story does a terrific job of summing up the speculation about the technology and the notion of the "escape velocity" -- i.e., that any set of technology which enables people to live to 130 will probably enable them to live indefinitely.
I've got no idea how probable any of this is, but it's just one of the (many) things which current economic and political theory has no imagination and no planning for.
Of course, one of the nifty things about the future is how what happens is always essentially unpredictable and completely radical from the standpoint of prior expectations.
I "agree" in principle with many of the things in the article, and yet I think the guy who wants to live long enough to live forever is also self obsessed and living on wishful thinking.
His views of how society will be turned upside down are childishly naive. This development would be treated just like everything else, including a visit by aliens. It will spawn some new fashions, people will still drink coffee in the morning, and it will be more of the same old same old. Literally.
Just imagine that a**hole neighbor of yours may be living there 1,000 years.
