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

Postscript Re: Ray Kurzweil

July 30, 2001 by Jaron Lanier

This postscript to his One Half of a Manifesto is a further discussion and criticism of exponential trends. Do these trends exist as predictive models, or are we playing connect-the-dots based upon an arbitrary selection of milestones and paradigm shifts?… read more

Taming the Multiverse

August 7, 2001 by Marcus Chown

In Ray Kurzweil’s The Singularity is Near, physicist Sir Roger Penrose is paraphrased as suggesting it is impossible to perfectly replicate a set of quantum states, so therefore perfect downloading (i.e., creating a digital or synthetic replica of the human brain based upon quantum states) is impossible. What would be required to make it possible? A solution to the problem of quantum teleportation, perhaps. But there is a further complication: the multiverse. Do we live in a world of schizophrenic tables? Does free will negate the possibility of perfect replication?… read more

How to Live in a Simulation

January 14, 2002 by Robin Hanson

If you might be living in a simulation then all else equal you should care less about others, live more for today, make your world look more likely to become rich, expect to and try more to participate in pivotal events, be more entertaining and praiseworthy, and keep the famous people around you happier and more interested in you.… read more

Radical body design “Primo Posthuman”

February 25, 2002 by Natasha Vita-More

Primo 3M+ is a prototype future body, a conceptual design with superlongevity in mind. Primo by design is multi-functional. It is reliable, changeable, upgradeable, and complete with enhanced senses. Primo is the new designer body.… read more

A Simple Model of Unbounded Evolutionary Versatility as a Largest-Scale Trend in Organismal Evolution

June 25, 2002 by Peter D. Turney

The idea that there are large-scale trends in the evolution of biological organisms, such as increasing complexity, is highly controversial. But Peter Turney presents a simple computational model showing that local adaptation to a dynamic, randomly changing environment results in a global trend towards increasing evolutionary versatility, which implies an accelerating evolutionary pace, and that this trend can continue without bound if there is sufficient ongoing change in the environment.… read more

How does the body react to medical nanodevices?

November 19, 2003 by Ralph C. Merkle

Nanomedicine, Volume IIA: Biocompatibility, the second volume in Robert A. Freitas, Jr.’s Nanomedicine series, has been published just in time to provide an authoritative scientific foundation to address the growing concerns about the biocompatibility of nanotechnology in the environmental and medical communities.… 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

Ray Kurzweil responds to John Brockman’s “The Edge” Annual Question of 2007

February 4, 2007 by Ray Kurzweil

Ray Kurzweil responds to John Brockman’s The Edge Annual Question – 2007: WHAT ARE YOU OPTIMISTIC ABOUT? WHY?… read more

Finishing the Unfinished Revolution

February 21, 2001 by Michael L. Dertouzos

In this manifesto, Dr. Dertouzos introduces a radical vision of human-centered computing intended to make computers more usable, based on natural interaction (such as speech recognition), automation, individualized information access, collaboration, and customization. MIT’s Oxygen project, a prototype to test these concepts, is summarized in this excerpt from The Unfinished Revolution (HarperCollins, 2001),… read more

Minimally Conscious States

April 17, 2001 by Douglas I. Katz

What exactly is the threshold of consciousness? One way to approach that core question is to explore “minimally conscious states,” a condition of severely altered consciousness in which the person demonstrates minimal but definite behavioral evidence of self or environmental awareness. Neurologist Dr. Douglas I. Katz has developed a precise set of measures that might serve as a checklist in the development of conscious computers.… read more

Texas thinks small, plans Nanotech Corridor

June 11, 2001 by Amara D. Angelica

Texas wants to be the nanotech equivalent of Silicon Valley. It has a good start north of Dallas: big bucks, top talent, leading university, and proximity to nanotech pioneering company Zyvex and the Telecom Corridor. But other centers around the country are also in the race to lead the nano world.… read more

Who Owns Intelligence?

September 24, 2001 by Howard Gardner

Before intelligence can be enhanced or artificially created, it has to be defined; this excerpt from Howard Gardner’s Intelligence Reframed ponders the different ways in which intelligence is quantified and conceived.… read more

Want to live to 200? Being a cyborg has advantages

November 2, 2001 by Garry Barker

Ray Kurzweil predicts that human identity will be called into question by the massive computers of the future.… read more

How are behaviors encoded in DNA?

January 21, 2002 by John McCarthy

The 5th Annual Edge Question reflects the spirit of the Edge motto: “To arrive at the edge of the world’s knowledge, seek out the most complex and sophisticated minds, put them in a room together, and have them ask each other the questions they are asking themselves.” John McCarthy asks: how are behaviors encoded in DNA?… read more
