 |
|
I found an article which expresses some of my discomfort
with Drexler's ideas:
``Flaws in Drexler's vision
It is nevertheless worth examining the shortcomings of
Drexler's original vision because this may give clues as
to how we might make radical nanotechnology feasible. Why,
for example, do illustrations of nanosubmarines look so
absurd to a scientific eye? The reason is that these
pictures assume that the engineering that we employ on
macroscopic scales can simply be scaled down to the
nano-scale. But physics looks very different at such
dimensions. Designs that function well in our macroscopic
world will work less and less well as they shrink in size. [...]''

The article goes on in some detail about how scaling
things down works poorly.
It doesn't contain any real criticism of assemblers, or
diamondoid materials, though.

That seems an odd point of criticism, given that artist impressions are
notably more wrong than right when it comes to nanotech illustrations.
But then if we told them to get it 100% technically correct or its back
to children's book illustrations, what would they put on the front of
magazine covers? ;-) |
