That's a complete guess from where the sun doesn't shine. The non-water
part of the human brain is about 0.15 kg and it's vastly insufficient. We
couldn't even figure out what it would take to recreate civilization and it
would certainly be enormous - gigatons of equipment and people, minimally.
How much more efficient could nanotech be? We don't know.

### If you have a self-replicating device (a few nanograms, like a human
cell) capable of reading (suitably transcribed) Library of Conges (the 2100
edition), with some added tech manuals (a small fraction of a gram), and a
source of energy (e.g. sunlight and a square millimeter of solar cell), you
could rebuild the civilization, complete with humans recreated from the
Genome Project data.

Like I said - propellant, not data, for space operations. It's big and
things
move very fast.

### But why do you need propellant if you can use your sail to maneuver to
an asteroid, crash land on the sunny side, and start growing?
