If you look at the human condition today, not everyone is well fed, has access to good medical care, or the physical basics that provide for a healthy and a happy life.
As in any technological revolution, there will be winners and losers. On balance, everyone will come out ahead, although there will be particular companies that will not be able to cope with a new environment.
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.
The first approximation in this future that we're looking at is that everyone will be physically well off. They will have a great abundance in material goods, and as a consequence, I think that will soften some of the conflicts we see now.
One of the concepts essential to molecular manufacturing is that of a self-replicating manufacturing system. That concept has lagged behind in its acceptance.
