Molecular nanotechnology is generally about atomic-scale or better
precision, not manipulation of isolated atoms.

If you look at the designs being put out by Drexler and others, it is
very clear they are talking about manipulating individual atoms.

I think that is true for diamondoid-type structures only. I.e., the
"individual atoms" are all of the same type, so that well-understood
and optimised specialised tools can be designed.

I suspect it would be counterproductive to have some kind of
"universal dissassembler" that examined each individual atom,
identified it, then used the appropriate tool to remove it
(somehow). The energy requirements would be enormous.

Of course you could use nanotechnology to enhance a more "traditional"
process. Grinding to dust, dissolving, filtering etc.
