Since 2000, he has studied and written about molecular manufacturing.

Especially since Xymos was developing technology in what the company called "molecular manufacturing," but which most people called nanotechnology.

One of the first things scientists learned about molecular manufacturing was how phenomenally difficult it was to carry out.

Even so, molecular manufacturing promises to lead to great advances in electronic devices, new materials of all sorts and the understanding of nature.

Other attempts at molecular manufacturing are being made in genetic engineering.

Yet today's research programs are not focused on developing the molecular machine technologies essential to molecular manufacturing.

Because many people I respected thought molecular manufacturing was impossible.

They further assert that their current plans for developing and using molecular manufacturing do not in fact include free-foraging replicators.

However, the report spent almost no time on molecular manufacturing.

This ignores the central issue - the feasibility of molecular manufacturing - in which nanobots play no role.
