We are looking at a future where to a first approximation everyone is wealthy.

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.

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

If you think the technology is infeasible, you don't worry about what it might do and what its potential is.

Today we see a human population of over 6 billion people, many of whom have serious medical conditions, which either can't be treated or cannot be treated economically.

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.

Nanotechnology is an idea that most people simply didn't believe.
