What we refer to as 'death' is just a set of symptoms that have proven resistant to treatment.

We see an entire planet which has many limitations.

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.

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.

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.

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.

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.
