OK, maybe biology could evolve and develop the tools to "eat" diamond(oid) structures eventually. However one has also to take into account the speed of the respective "metabolisms". MNT produced systems will have much faster "metabolism". They will be able to repair and reproduce faster than biological systems, providing that enough energy is available. If the energy resource is scarce, and efficient energy usage a requirement, then matters get more complicated. Although I dare to wager that even in that case artificial systems can still out-class biological systems. Basically, what I'm claiming is, that for every function you can imagine, an artificial system can be made that will perform better than its biological counterpart. Claiming otherwise accounts to biological centrism. However, as I told before, that biological hostile organisms will form no threat to artificial organisms will not matter much in the future. Because an artificial ecology will develop, and one will still have to into account hostile organisms (but not biological ones). (Just as in the "computer-software-world" one has to take into account software based virusses, worms etc..) Again, systems and organisms based on biology (i.e. DNA, proteins, etc..) will not be able to compete with artificial organisms (e.g. based on MNT).
