Optimism exists on a continuum in between confidence and hope. Let me take these in order.

I am confident that the acceleration and expanding purview of information technology will solve within twenty years the problems that now preoccupy us. -- Consider energy. We are awash in energy (10,000 times more than required to meet all our needs falls on Earth) but we are not very good at capturing it. That will change with the full nanotechnology-based assembly of macro objects at the nano scale, controlled by massively parallel information processes, which will be feasible within twenty years. Even though our energy needs are projected to triple within that time, we'll capture that .0003 of the sunlight needed to meet our energy needs with no use of fossil fuels, using extremely inexpensive, highly efficient, lightweight, nano-engineered solar panels, and we'll store the energy in highly distributed (and therefore safe) nanotechnology-based fuel cells. Solar power is now providing 1 part in 1,000 of our needs, but that percentage is doubling every two years, which means multiplying by 1,000 in twenty years.

Almost all the discussions I've seen about energy and its consequences (such as global warming) fail to consider the ability of future nanotechnology-based solutions to solve this problem. This development will be motivated not just by concern for the environment but also by the $2 trillion we spend annually on energy. This is already a major area of venture funding.

Consider health. As of just recently, we have the tools to reprogram biology. This is also at an early stage but is progressing through the same exponential growth of information technology, which we see in every aspect of biological progress. The amount of genetic data we have sequenced has doubled every year, and the price per base pair has come down commensurately. The first genome cost a billion dollars. The National Institutes of Health is now starting a project to collect a million genomes at $1,000 apiece. We can turn genes off with RNA interference, add new genes (to adults) with new reliable forms of gene therapy, and turn on and off proteins and enzymes at critical stages of disease progression. We are gaining the means to model, simulate, and reprogram disease and aging processes as information processes. In ten years, these technologies will be 1,000 times more powerful than they are today, and it will be a very different world, in terms of our ability to turn off disease and aging. ...   more »

I can vouch for John Todd's research. I knew him back in the 70's and was impressed then with the quality of his work. His "Eco Machines" are the outcome of 30 years of research and trial and error experimentation. ~ ronjon

Social responsibility, sustainability, and 'natural capitalism' are becoming new models for governments and corporations in the 21st century...

The ECO Machine - a wastewater treatment system that naturally treats sewage and industrial waste to re-use quality. An important consideration as fresh water becomes one of the most important commodities in the new millennium...ECO Machines bring advanced wastewater treatment technology, and unsurpassed aesthetic, economic, and environmental advantages to companies, communities, and resorts both at home and internationally.

ECO Machines accelerate nature's own water purification process. Unlike chemical-based systems, ECO Machines incorporate helpful bacteria, fungi, plants, snails, clams, and fish that thrive by breaking down and digesting organic pollutants, pollutants that normally deprive the water of oxygen. This clean, simple approach efficiently transforms high-strength industrial wastewater and sewage into water clean enough to be recycled for reuse. ...   more »
