Culture and nanotechnology is almost a whole chat topic by itself. I deal with that a lot. And I think that the future is hard upon us in a big way as regards genetic engineering. For instance, they are growing human ears on the backs of mice. Think about it.
Immortality is a common theme in nanotech fiction.
Kathy and I have both touched on it, though in very different ways. There are a lot of different avenues being explored to prolong life. I think that nanotech will definitely be put into play in this regard. With attendant social problems if it succeeds. It's obviously one of the things people will want most, though it may also be one of the hardest to deliver.
