I haven't been able to follow this thread that closely, Lyle, and just
yesterday I was saying in a meeting of extropians here in Houston that I
think your "Geniebusters" web site is worthwhile (if wrong in some respects
-- I do think you're attacking a straw man in many instances and, yes, I've
read it.) But let me offer a comment about "grey goo", nanotechnology and
threats to Life the Universe and Everything.
The very specific threat discussed a long time ago in sci.nanotech that was
given the name "grey goo" is but one possible harmful use of molecular-scale
technology and I express no judgment about its plausibility here. However, I
have been convinced by some pretty rigorous reasoning, explained by some
pretty smart people, that one does NOT need to make a "genie machine" or even
a "general-purpose assembler" to cause Very Bad Things to happen with
molecular scale technology. In fact, I'm so convinced of this that I think
it's irresponsible to discuss the details of such ideas in an open, public
forum. Suffice it to say, Lyle, that a technology capable of causing severe
destruction on a scale up to and including the level of a planetary ecology
can be created with molecular technology well short of a general-purpose
assembler. Here's a hint: consider the kind of havoc that computer virii can
cause, even though we're nowhere close to "general-purpose artificial
intelligence"; all that's required is the capacity for self-replication.
