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 »

Beyond the Central Dogma of Physics, by SCIY Editor Ulrich Mohrhoff

by ronjon on November 7, 2007 03:28PM (PST)

...In physics, too, there is a Central Dogma, which I have dubbed ‘the evolutionary paradigm’. It is the notion that physics can be neatly divided into a kinematical part, which concerns the description of a physical system at an instant of time, and a dynamical part, which concerns the evolution of a physical system from earlier to later times.

The laws of physics are correlation laws. In classical physics, states are correlated deterministically, so earlier states can be used to predict later states (and later states can be used to retrodict earlier states). Quantum physics correlates measurement outcomes statistically, so earlier measurement outcomes can be used to predict the probabilities of the possible outcomes of later measurements (and later measurement outcomes can be used to retrodict the probabilities of the possible outcomes of earlier measurements). Because the quantum-mechanical correlation laws are genuinely probabilistic, they may not conform to the evolutionary paradigm.

And they don’t. For one thing, the time-symmetry of the laws of physics is at odds with the unidirectionality of the evolutionary paradigm, which has its roots in a physically unwarranted projection into the world of the way we perceive the world. (This casts doubt on the appropriateness of the evolutionary paradigm even for classical physics.) For another thing, the interpretation of a quantum state as an evolving physical state (rather than as a mere computational device) gives rise to no end of pseudo-questions (and gratuitous answers), such as the notorious questions of where and when and how (and with respect to which basis) the wave function collapses ... more »

Philosophy and religion, between exchange and tension: by Mohammed Arkoun

by ronjon on November 4, 2007 05:46PM (PST)

“Islamizing” modernity instead of modernizing Islam – preposterous! worries Professor Mohammed Arkoun. A refuge in poor countries, a rejection of “tele-techno-scientific reasoning” in rich countries, religiosity is spreading in the world at the expense of humanist values and philosophical thinking. ... more »
