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

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

The new technologies that we see coming will have major benefits that will greatly alleviate human suffering.

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.

Because of technological limits, there is a certain amount of food that we can produce per acre. If we were to have intensive greenhouse agriculture, we could have much higher production.

One of the things that we can say with confidence is that we will have much lighter, much stronger materials, and this will reduce the cost of air flight, and it will reduce the cost of rockets.

Machines built by human beings they will function correctly if we provide them with a very specific environment. But if that environment is changed they won't function at all.
