"grey goo" beyond the natural goo, as often seen in fiction, multiplies and moves so fast as to violate basic laws of physics. For example there's only so much energy stored in stuff that could be eaten.
Answer: No free lunch, every advantage carries a cost. Any "super" bug we come up with will enter a world with vicious competitors who've been with us since long before the dinosaurs.
Or to put it another way, what happened since bacteria have been around? Humans. Humans started out as single celled creatures like bacteria. And if we can get from that to humans, is it not reasonable to assume that bacteria have had the time to figure out how to multiply as fast as possible?
