What the hell are these nanites living on?! Their very life requires
energy, not to mention, as Anders noted, the cost of trying to
concentrate extremely diffuse and oxygen-bonded uranium. Solar
collection will take lots of area, be noticeable, and be exposed. Shade
it, dust it, bomb it. Oh, not to mention the probable heat emissions
from all this activity. We're talking very unstealthy things here.

And they're not living off of rock. It's hard to get lower energy
states than found in a lot of rock without using nuclear processes.
That's why aluminum mining is so expensive.

I challenge this "lower division" assumption. Antibodies can't gum up
the works of nanites; phagocytic cells can't enclose and dissolve them?
Hydrogren peroxide and free radicals are popular weapons. Oxidizing
chemicals vs. small pieces of pure carbon; I bet on the white blood cell.

Remember, life is nanotechnology. The design is obscure and it's all
wet. Defensively, the latter is not necessarily a disadvantage.

Yes. So, is it easier to create nanites in a hostile environment, or
destroy them?

And is the energy state of diamondoid material higher than that of
organic material? Probably, in which case this gray goo plague needs
constant input or can only grow by processing lots of material -- which
means that it grows very slowly.

Wait, diamond nanites are attacking diamond skin? If there's so much
energy for the plague to live on, obviously your outer defense shouldn't
be a hard shell, it should be a friendly counter-plague, like the
friendly flora living on our mucous membranes.

Damn complex plague, building explosives in a coordinated manner. You
sure it doesn't have internal communiation lines that can be attacked?
