I mean, I think it's also not quite sound to go "oh, it's been 18 years and we haven't been converted to grey goo yet, I guess it was a false alarm, phew." Giv

  Grey goo fails because it's stuck with the same chemistry life is built off of. You can't use much iron for your self replication because there is not much iron in the environment. You also need an energy source and storage etc. End result you end up building using organic chemistry which means your goo get's eaten.

    Couldn't you make grey goo out of silicon? There's more silicon than anything else in the rocks of this planet. It could produce its energy by photovoltaic cells. Blanket the entire planet in a seething mass of solar-powered nanobots. That's what I think of when I hear the term 'grey goo.'
