Manufacturing takes place in very large facilities. If you want to build a computer chip, you need a giant semiconductor fabrication facility. But nature can grow complex molecular machines using nothing more than a plant.

We can grow crops less expensively because molecular manufacturing technology is inherently low cost.

A potato can grow quite easily on a very small plot of land. With molecular manufacturing, we'll be able to have distributed manufacturing, which will permit manufacturing at the site using technologies that are low-cost and easily available.

One of the concepts essential to molecular manufacturing is that of a self-replicating manufacturing system. That concept has lagged behind in its acceptance.

Disease and ill health are caused largely by damage at the molecular and cellular level, yet today's surgical tools are too large to deal with that kind of problem.

Nanotechnology will let us build computers that are incredibly powerful. We'll have more power in the volume of a sugar cube than exists in the entire world today.
