We see an entire planet which has many limitations.
Nanotechnology is an idea that most people simply didn't believe.
We are looking at a future where to a first approximation, everyone is wealthy.
We can grow crops less expensively because molecular manufacturing technology is inherently low cost.
If you think the technology is infeasible, you don't worry about what it might do and what its potential is.
The new technologies that we see coming will have major benefits that will greatly alleviate human suffering.
Food is available, but it cannot be shipped into an area, so the people in that area suffer the consequences.
If we attempt to block the development of new technology, we effectively have ensured that the most responsible parties will not develop them.
If you look at the various strategies available for dealing with a new technology, sticking your head in the sand is not the most plausible strategy.
One of the concepts essential to molecular manufacturing is that of a self-replicating manufacturing system. That concept has lagged behind in its acceptance.
