The cost of WoMD is much less than the cost of
defenses against them.

If you have time to disperse and go stealth is the 
question.  A speed of light attack with no
warning would negate any such planning.  Only
existing in SND mode all the time can limit such
Even under SND huge computational power will
be available.  I am not certain we can project
advantages more than a few magnitudes beyond
what the human brain and currently technology
can do.  Does a cluster of scattered AI say 10**4 
beyond human really have a disadvantage over
a centralized AI of say 10**6  beyond human.
At what point does adding more and more
capability produce diminishing returns?  Is there
something a 10**20 brain can do that that many
lesser brains cannot?
I know that at our scale better and bigger brains
do prove themselves.  We also see that many of
our best brains have mental health issues.
How does mental health in AI scale with size
and capability?  It is really a question of stability
during scaling.  If you put everything into a single
Mbrain and it is mentally unstable is that a foolish
