We see an entire planet which has many limitations.

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

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.

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.

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