[Note to Extro readers: Herewith, some recent parts of a discussion I
have been having off line. Apologies for the reverse chronological
layout....]

Since what we can actually do with MNT today is nonexistent, i.e., since
MNT doesn't exist yet, there is a lot of "here there be dragons"
sentiment possible once you hear of the concept of gray goo. It's a very
powerful image of an utter earthly cataclysm. It behooves us to address
this as prudently as we are able.

The first thing to be published that might qualify as "research" on gray
goo is Robert Freitas, _Some Limits to Global Ecophagy by Biovorous
Nanoreplicators, with Public Policy Recommendations_, available online
(I think the URL is www.foresight.org/NanoRev/Ecophagy.html).
I think there may be some holes in that. Go for it!

See also the Foresight proposed guidelines on MNT research, modeled
after the accepted guidelines for biology.

These are recent, concrete attempts to formally and publicly address
this issue. And please note that various people in the media are having
fun with how wiggy, far out and science fictional these documents are,
since they can always get a sound bite from some scientist saying that
assemblers, replicators or disassemblers are utter bilge. Well, they're
not utter bilge just because they don't show up on his radar.

As I mentioned, and as I suspect Eric might agree, a bigger risk is from
things closer to home: biotech hybridized or enhanced, with or without
MNT. Bio already has the replication trick down.

Now, do you want to call anything that replicates and kills people "gray
goo"? I don't.
