NANOTECHNOLOGY UPDATE: Progress in mass-producing graphene.

Meanwhile, last week I noted successful demonstrations of mechanosynthesis, and noted that this proved some critics wrong. I just happened to run across this passage from Wired from 2004:

In practice, Drexler’s critics charge, chemistry is more complicated. Each atom in a molecule interacts with every other atom nearby, including those in the proposed tool tips, conveyor belt, mill wheel, and so on. Thus, to deposit a single atom, a nanoassembler would need to restrain every atom in the vicinity. The sheer number of atoms that would need to be controlled, and the machinery it would take to control them, make mechanosynthesis a practical impossibility.

Apparently, not so much. I suspect that Eric Drexler will have the last laugh where these critics are concerned.
