Michael Vassar, Michael Vassar, in time of need I summon thee; please, tell unto Less Wrong your thoughts on probable times of important molecular nanotechnology advances, and what such advances would mean practically/strategically speaking!
(it's worth a shot)
Ralph Merkle at Singularity University gives a contemporary introduction to molecular nanotechnology in this video (1hr, 13min). Great way to be introduced to the subject, especially if your eyes get tired from too much reading.
From 2009, but as far as I can tell, not yet linked from Less Wrong.
