About Ralph Merkle: Ralph C. Merkle is a computer scientist. He is one of the inventors of public key cryptography, the inventor of cryptographic hashing, and more recently a researcher and speaker on molecular nanotechnology and cryonics.
We see an entire planet which has many limitations.
The new technologies that we see coming will have major benefits that will greatly alleviate human suffering.
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.
One of the concepts essential to molecular manufacturing is that of a self-replicating manufacturing system. That concept has lagged behind in its acceptance.
Nanotechnology is an idea that most people simply didn't believe.
It looks as though yields of over 10 times what we can currently grow per acre are feasible if you control the CO2 concentration, the humidity, the temperature, all the various factors that plants depend on to grow rapidly.
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.
One of the issues facing us today is that there are countries where there is a serious lack of resources, the standards of living are very low, and this creates a fundamental unease and discomfort in entire populations.
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.
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.
A potato can grow quite easily on a very small plot of land. With molecular manufacturing, we'll be able to have distributed manufacturing, which will permit manufacturing at the site using technologies that are low-cost and easily available.
We can grow crops less expensively because molecular manufacturing technology is inherently low cost.
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.
If you think the technology is infeasible, you don't worry about what it might do and what its potential is.
If you look at the various strategies available for dealing with a new technology, sticking your head in the sand is not the most plausible strategy.
If we attempt to block the development of new technology, we effectively have ensured that the most responsible parties will not develop them.
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.
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.
