article about Nanotechnology on rationalwiki

[chris0033547]

I just wanted to hear your opinions about the following article on RationalWiki:

http://rationalwiki.org/wiki/Nanotechnology

Is the kind of technology, Drexler proposes, really so "magical"? I mean our own bodies consist of millions of different cells (our biological microrobots), which are somehow coordinating each other, can reproduce, can deliberately move around the body (- some of them -) and manage to work together thus giving rise to our macroscale bodies. Aren't we ourselves the living empirical evidence that Molecular Nanotechnology is possible? And yet the above article is written in a rather negative tone. But is such a tone justified?

(The only field, where I cannot think of a fitting analogy from nature is hylonanotechnology.)
