Nanotechnology will let us build computers that are incredibly powerful. We'll have more power in the volume of a sugar cube than exists in the entire world today.
Disease and ill health are caused largely by damage at the molecular and cellular level, yet today's surgical tools are too large to deal with that kind of problem.
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.
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.
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.
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 the cost of rockets.
A molecular manufacturing technology will let us build molecular surgical tools, and those tools will, for the first time, let us directly address the problems at the very root level.
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.
There are certain things that are inherently scarce. For example, there is only a certain amount of beachfront property in California. It is going to be scarce, it is going to be expensive.
The laws of physics should allow us to arrange things molecule by molecule and even atom by atom, and at some point it was inevitable that we would develop a technology that would let us do this.
