well, i guess that means i should back off my russian nuke sub obtainment plans, and lay off my attempts to stockpile the necessary vodka, kailua, and (powdered) milk... ;)

so would someone please comment (or point me to a relevant archive ref) on the relative difficulties of moravic-style uploading versus the creation of gray goo? was the recent lobster neuron replacement really much of a milestone, as in, how far ahead of or behind 'schedule' was it? how are things shaping up on this front? and how does the fact that soft nanotech research is improving far faster then hard nanotech research enter into this?
