I'm pretty sure that a gray goo nanotech disaster is generally not considered plausible--if nothing else, it would generate so much heat the nanotech would fail.

This argument can't be valid, because it also implies that biological life can't work either. At best, this implies a limit on the growth rate; but without doing the math, there is no particular reason to think that limit is slow.

Grey goo is assumed to be a really fast replicator that will eat anything. Arguably, it's a movie plot disaster.

From that thread, it seems that many people like to speculate on possible disasters.

The point is that they know they're doing it for the fun of it rather than actually coming up with anything that needs to be prevented.
