I’m with you; of the items that christina originally listed, SENS is the really important one. Nonbiological nanodevices or nanoconstructs might be useful as delivery systems or probes, but mostly we should be interested in biology all the way, e.g. designer bacteria as “medical nanobots”. Full-spectrum nanotechnology, and techniques for storing brain information, are really about opening the abyss of posthuman possibilities, and that’s a severe challenge whose resolution ought to be intimately involved with however the human attempt at coexistence with artificial intelligence works out. But human rejuvenation is comparatively :-) straightforward and should be on everyone’s to-do list.
