I first heard of either.  No matter how large and how fortified - if

it can't run and it can't hide - it is a target. Dennis May

 

 

Dennis, on the contrary sir.  An MBrain would have a most effective defense
against any incoming weapon, either a natural object or a projectile made by
alien hands (tentacles?) with apparent intent to harm.

 

The MBrain would have a number of orbiting telescopes orbiting outboard of
the last layer of nodes, constantly scanning the cosmos for any incoming
object.  If any of the telescopes spot anything, another one or two scopes
lock on and determine its distance and path via parallax.  If the object is
on a collision course with the MBrain, then all 10^26 nodes pivot to focus
sunlight on the incoming weapon or icy body, with similar results in either
case: vaporizing it while still weeks or months away.  

 

The MBrain is a target, in a sense, but certainly not a helpless target.
This one has a built-in speed of light self-defense system.
