Why should a grey goo be disassembling diamondoid? The only reason
would seem to keep down the blue, which would require
recognition. Notice that blue is static, as autoreplicating blue
would seem to be basically undistinguishable from grey. Blue is
brittle, and more complex than grey, so it will be outperformed anyway.

Why 'shell'? This is free environment. The grey grow as a thin
layer over organical materials. Grey cannot function under anaerobic
conditions. Of course distinct erosion pattern, or even cooperative
behaviour could evolve, which transports oxygen actively within volume

If the capability to erode diamondoid has evolved, the capability to
thrive in unstable environments will not be long to follow.

Funny, I think the problem is at least nondecideable with our current
knowledge. My intuition even tells me that grey has a slight or even
noticeable advantage, which makes it fundamentally uncontainable once
beyond a certain autoamplification stage.
