"We don’t even have micromachines. Mechanical objects on microscales do not exist." That's not exactly true. See, for example http://www.dartmouth.edu/~news/r

"We don’t even have micromachines. Mechanical objects on microscales do not exist." That's not exactly true. See, for example http://www.dartmouth.edu/~news/releases/2005/09/14.html http://www.dartmouth.edu/~news/releases/2005/09/14.html for a 60 micrometers by 250 micrometers robot from 2005. Of course, that's not nanotechnology, and the article's main point might well be valid. Still, there seems to be a good deal of exaggeration in it.
