 I agree with your main point. We need to spend less time yelling at
each other and more time trying to identify our actual points
of disagreement.

True. Read NANOSYSTEMS, not just "Unbounding the Future", etc. I intend
this as a positive suggestion, not as the "generic canonical aswer to
all pleas for detail." In particular. I'll try hard not to refer to
NANOSYSTEMS in response to a detailed question unless I cite a specific
paragraph. In this case, you are making a broad requiest, so I'm giving
a
broad answer.

   Nope. If nanotech has any validity, then out-of-control naneotech is
not
a large incremental leap.

   Good question. If "we" implies a community of humans, and it they
used
nanotech to leave earth, then unless they police the entire community,
they
run the risk of "wild" namotech.

     Quite possibly. Its a race between Trancendence (via the
singularity?)
  and the gray goo.

   Nope. I don't understand how people on this list can reject the
premises just because the consequences are both strange and frightening.

I think you are asking for a bit too much for this list. I'd be
satisfied wit a simple statement that he considers it impracticable,
with
a brief sketch of the reasons such as you give below. That would be
sufficient to permit us to understand our differences and examine them
further without rancor.

 I've never seen atom-by-atom scanning mentioned seriously except in
science fiction. Do you have a reference?

  This one needs a bit more excplication. We already do top-down design,
fromn the level of city planning down to the level of individual
circuits
within a microprocessor. Why is this qualitatively harder when designing
the smallest components from atoms? even if every single component must
be designed by a human, we still get "free" manufacturing. The design
effort is a very small part of the cost of a consumer item.
