Another way nanotech could help "protect" against these and other
macroweapons is by keeping a running tally of the state of your brain in
multiple hard-to-destroy nodes in your body, possibly uploading deltas
to a central site. It would protect by providing all the necessary
information to reconstitute you in the event of major trauma.

Of course, by the time we have nanotech this mature we'll probably all
be multiply redundant uploaded entities, anyway.
