Molecular Manufacturing: Too Dangerous to Allow?

March 26, 2006 by Robert A. Freitas Jr.

Despite the risks of molecular manufacturing, such as global ecophagy, replication is not new. Engineered self-replication technologies are already in wide commercial use and can be made inherently safe. And defenses we’ve already developed against harmful biological replicators all have analogs in the mechanical world that should provide equally effective, or even superior, defenses.… read more

Nanomedicine

November 18, 2003 by Robert A. Freitas Jr.

In Nanomedicine, Vol. I: Basic Capabilities, first in the four-volume Nanomedicine technical book series, Robert A. Freitas, Jr. offers a pioneering and fascinating glimpse into a molecular-nanotechnology future with far-reaching implications for the medical profession — and ultimately for the radical improvement and extension of natural human biological structure and function.… read more

Nanotechnology, Nanomedicine and Nanosurgery

February 13, 2006 by Robert A. Freitas Jr.

The ability to build complex diamondoid medical nanorobots to molecular precision, and then to build them cheaply enough in sufficiently large numbers to be useful therapeutically, will revolutionize the practice of medicine and surgery.… read more

Respirocytes

May 20, 2002 by Robert A. Freitas Jr.

An artificial nanomedical erythrocyte, or “respirocyte” — intended to duplicate all of the important functions of the red blood cell — could serve as a universal blood substitute, preserve living tissue, eliminate “the bends,” allow for new sports records, and provide treatment for anemia, choking, lung diseases, asphyxia, and other respiratory problems.… read more

Robots in the bloodstream: the promise of nanomedicine

February 26, 2002 by Robert A. Freitas Jr.

In just a few decades physicians could be sending tiny machines into our bodies to diagnose and cure disease. These nanodevices will be able to repair tissues, clean blood vessels and airways, transform our physiological capabilities, and even potentially counteract the aging process.… read more

Say Ah

May 23, 2001 by Robert A. Freitas Jr.

Nanorobots the size of bacteria might one day roam people’s bodies, rooting out disease organisms and repairing damaged tissue.… read more

Tangible Nanomoney

July 9, 2002 by Robert A. Freitas Jr.

Robert Freitas, author of the recently-published groundbreaking technical book Nanomedicine, reflects on how we might pay for very advanced medicine — or indeed, pay for anything at all — in a world where artificial molecular machine systems are commonplace. Hint: Perhaps we’ll be using coins made of tantalum or ununquadium!… read more

The Gray Goo Problem

March 20, 2001 by Robert A. Freitas Jr.

In Eric Drexler’s classic “grey goo” scenario, out-of-control nanotech replicators wipe out all life on Earth. This paper by Robert A. Freitas Jr. was the first quantitative technical analysis of this catastrophic scenario, also offering possible solutions. It was written in part as an answer to Bill Joy’s recent concerns.… read more

The Vasculoid Personal Appliance

October 22, 2002 by Robert A. Freitas Jr.

Robert A. Freitas Jr. (author, “Nanomedicine”) visualizes a future “vasculoid” (vascular-like machine) that would replace human blood with some 500 trillion nanorobots distributed throughout the body’s vasculature as a coating. It could eradicate heart disease, stroke, and other vascular problems; remove parasites, bacteria, viruses, and metastasizing cancer cells to limit the spread of bloodborne disease; move lymphocytes faster to improve immune response; reduce susceptibility to chemical, biochemical, and parasitic poisons; improve physical endurance and stamina; and partially protect from various accidents and other physical harm.… read more

Interview: How much do we need to know?

July 10, 2006 by Bill Joy

To limit access to risky information and technologies by bioterrorists, we should price catastrophe into the cost of doing business, rather than regulate things, says Bill Joy. Things judged to be dangerous would be expensive, and the most expensive would be withdrawn.… read more

Forecasts and Alternative Futures

February 19, 2002 by Sohail Inayatullah

This third chapter from Situating Sarkar:Tantra, Macrohistory and Alternative Futures explores non-Western future visions, where progress can be seen in a more spiritual than materialistic light, through the eyes of poet and visionary Prabhat Rainjan Sarkar.… read more

Rethinking Science and Culture: P.R. Sarkar’s Reconstruction of Science and Society

February 19, 2002 by Sohail Inayatullah

The ninth chapter of Situating Sarkar: Tantra, Macrohistory and Alternative Futures by Sohail Inayatullah proposes alternatives to the Western conceptions of science, data, and consciousness, as well as the roles science plays within society.… read more

The Rights of Robots: Technology, Culture and Law in the 21st Century

August 6, 2001 by Sohail Inayatullah, Phil Mcnally

Robot rights are already part of judiciary planning–can sentient machines be far off? This discussion of robot rights looks in-depth at issues once reserved for humans only.… read more

The Rights of Your Robots: Exclusion and Inclusion in History and Future

August 6, 2001 by Sohail Inayatullah

Sohail Inayatullah is preparing for a world in which machines become sentient and begin to demand rights–this article discusses how the machines will participate in their destiny.… read more

Jim Lehrer News Hour: Interview with Ray Kurzweil

September 27, 2001 by Jim Lehrer News Hour

David Gergen, editor-at-large of U.S. News and World Report, talks with inventor Ray Kurzweil about his prediction that computers will attain the memory capacity and computing speed of the human brain by around 2020.… read more
