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.

Lighter computers and lighter sensors would let you have more function in a given weight, which is very important if you are launching things into space, and you have to pay by the pound to put things there.

Many people in the world today are not starving because there is an inherent inability to produce food, they are starving because they are caught in the middle of political fights and blockades that have been used as weapons.

Food is available, but it cannot be shipped into an area, so the people in that area suffer the consequences.

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.

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.

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.

If we can reduce the cost and improve the quality of medical technology through advances in nanotechnology, we can more widely address the medical conditions that are prevalent and reduce the level of human suffering.

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 we can reduce the cost and improve the quality of medical technology through advances in nanotechnology, we can more widely address the medical conditions that are prevalent and reduce the level of human suffering.
