People will be surprised at how fast space develops, because right now, a very bright core of nano-space enthusiasts have engineering plans, awaiting the arrival of the molecular assembler. People like Forrest Bishop have wonderful plans for space transport and development, capable of being implemented in surprisingly short time frames. I think Mars will be teraformed in less time than it takes to build a nuclear power plant in the later half of the good old, backward 20th century. An explosion in the arts and service industries are to be expected when no fields need to be plowed for our daily bread, similar to the explosion when agriculture became mechanized and efficient and the sons and daughters of farmers migrated to cities. This explosion will be exponentially greater.
Molecular machines are just small machines.
We all have our talents to contribute. Perhaps this may be the greatest opportunity in history to express talents. An explosion of new endeavors and professionals of such endeavors. Perhaps when I order that extra gray matter, my answer will be more imaginative. Ah, the freedom to imagine, then build.
