The Great Mambo Disappointment and the Cynical Condition Monday, May 19 2008 

Ed Regis is a science journalist type I’ve always liked, mainly for 1995 book Nano, which got me into nanotechnology when I was 11. Although the book generally has good reviews on Amazon, I had to post this one, by Robert J. Crawford:

As a professional reviewer, once in a while you come across a book that is so ridiculously bad, that so appallingly falls short of what the author claims, that you wish you had never contracted to review it because that means you have to carefully read it. Of the hundreds of popular science books that I have read, I can say without hesitation that this one may be the worst. And yet its tone is utterly arrogant and self-satisfied. It is truly a monument to the author’s egotism.

Though billed as a science book, there simply is no science in it. Instead, it is a kind a hagiographic biography of Eric Drexler, who has done nothing but talk.

However, if you are uncritically convinced of Drexler’s vision, which is nothing if not arresting, you will probably like this book. What it does is seek to elevate Drexler to prophet status before he has accomplished anything but unproven hypotheses at best, and speculation and hype at the worst.

Since his “hagiographic” worship of Dr. Drexler in 1995, Ed Regis has totally changed his mind. For instance, in a 2001 interview with Nanotech Now, he had this response:

Nanotech Now: With the advent of mature MNT, where do you see the most drastic changes occurring? How can society and industry prepare for it?

Ed Regis: “Advent of mature MNT”? You’ve got to be joking. The one thing that has most impressed me about MNT since I’ve been aware of the field, which I guess has been for about 15 years, is the snail’s pace of progress toward the goal. We’ve seen tons of conferences, books, theories, predictions, discussions, workshops, institutes, companies, scenarios, simulations, pictures, articles, initiatives, meetings, study groups, Web sites, magazines, newsletters, matching grants and unmatching grants, et cetera. The one thing we haven’t seen is any substantial progress toward MNT.

I also question the common assumption that we have to “prepare for it.” I see no reason why we cannot simply wait until it happens, and then accommodate ourselves to it then and there, after the fact, when, if, and as it occurs. I think a lot of this before-the-fact worrying, handwringing, theorizing, scenarioizing, worst-case and best-case planning, et cetera, is a waste of time, especially in the event that the hoped-for revolution does not occur, or does not occur in the time frame envisioned by its prognosticators.

Most people have had no trouble accommodating themselves to all sorts of incredible technological feats, everything from the moon landing to the Concorde, VCRs, CAT scans, heart and lung transplants, hip replacements, cloned sheep, and truly stylish Japanese sports cars. Who would have thought!

The tone here sounds a bit bitter — Mr. Regis is disappointed that his dreams were crushed when the Great Nanotechnology Revolution didn’t occur soon enough. No need to be so sad, the 21st century is just getting started.

As you might have guessed, I totally disagree with Mr. Regis. There has been progress towards MNT. (See some of the talks at Future Current for a small sampling.) It’s a huge deal, and preparing for it is critical. Numerous scientists, futurists, and VCs start thinking about it for the first time every day. We ignore it at our peril.

The next Google could be a molecular nanotechnology company.

I just wanted to post Regis’ comments to make it obvious that there are people who have lost their faith in MNT, and regarding what bit of faith they have left, they still think it isn’t worth preparing for. That’s their choice, and I disagree. Much of the preparation work for MNT arms control and regulation issues overlaps strongly with legal/sociological issues surrounding rapid prototyping, and those are already materializing as we speak.

Honestly though, I think it’s worth snickering a little bit at Mr. Regis’ earlier overconfidence in the nearness of molecular assemblers. When asked by Edge.org “what have you changed your mind about?”, he said:

I used to think you could predict the future. In “Profiles of the Future,” Arthur C. Clarke made it seem so easy. And so did all those other experts who confidently predicted the paperless office, the artificial intelligentsia who for decades predicted “human equivalence in ten years,” the nanotechnology prophets who kept foreseeing major advances toward molecular manufacturing within fifteen years, and so on.

Mostly, the predictions of science and technology types were wonderful: space colonies, flying cars in everyone’s garage, the conquest (or even reversal) of aging. (There were of course the doomsayers, too, such as the population-bomb theorists who said the world would run out of food by the turn of the century.)

But at last, after watching all those forecasts not come true, and in fact become falsified in a crashing, breathtaking manner, I began to question the entire business of making predictions. I mean, if even Nobel prizewinning scientists such as Ernest Rutherford, who gave us essentially the modern concept of the nuclear atom, could say, as he did in 1933, that “We cannot control atomic energy to an extent which would be of any value commercially, and I believe we are not likely ever to be able to do so,” and be so spectacularly wrong about it, what hope was there for the rest of us?

And then I finally decided that I knew the source of this incredible mismatch between confident forecast and actual result. The universe is a complex system in which countless causal chains are acting and interacting independently and simultaneously (the ultimate nature of some of them unknown to science even today). There are in fact so many causal sequences and forces at work, all of them running in parallel, and each of them often affecting the course of the others, that it is hopeless to try to specify in advance what’s going to happen as they jointly work themselves out. In the face of that complexity, it becomes difficult if not impossible to know with any assurance the future state of the system except in those comparatively few cases in which the system is governed by ironclad laws of nature such as those that allow us to predict the phases of the moon, the tides, or the position of Jupiter in tomorrow night’s sky. Otherwise, forget it.

Further, it’s an illusion to think that supercomputer modeling is up to the task of truly reliable crystal-ball gazing. It isn’t. Witness the epidemiologists who predicted that last year’s influenza season would be severe (in fact it was mild); the professional hurricane-forecasters whose models told them that the last two hurricane seasons would be monsters (whereas instead they were wimps). Certain systems in nature, it seems, are computationally irreducible phenomena, meaning that there is no way of knowing the outcome short of waiting for it to happen.

Formerly, when I heard or read a prediction, I believed it. Nowadays I just roll my eyes, shake my head, and turn the page.

It’s important to remember that it’s possible to make predictions about the future that are entirely correct, as long as you’re not excessively specific. Anyone that makes money on the stock market or who runs a startup knows how to take risks and make predictions on a 2-5 year timeframe. If you have an above-average ability to predict the future, you can potentially use it to collect free money on the prediction markets. But most of the time, anything we predict is just a guess.

Life extension, risk prevention, human enhancement, etc., are worth pursuing for their own sake, no matter how long it takes, not to fulfill some rigid timeline or vision. Even incremental gains can be incredibly beneficial.

H/t to Mark Plus for bringing this to my attention.

(For those not in the know, the name of this post is a play on Regis’ other book, The Great Mambo Chicken and the Transhuman Condition.)

Nanotechnology? What are you talking about? Tuesday, May 6 2008 

Great article on the definition of nanotechnology over at Nanowerk. It starts like this:

Ask 10 people what nanotechnology is and you will get 10 different answers.

Trying to define nanotechnology is like the famous tale of the blind men and the elephant: Six blind men were asked to determine what an elephant looked like by feeling different parts of the elephant’s body. The blind man who feels a leg says the elephant is like a pillar; the one who feels the tail says the elephant is like a rope; the one who feels the trunk says the elephant is like a tree branch; the one who feels the ear says the elephant is like a hand fan; the one who feels the belly says the elephant is like a wall; and the one who feels the tusk says the elephant is like a solid pipe. It’s the same with nanotechnology – it is different things to different people.

And then there are all these terms floating around: ‘bottom-up’ and ‘top-down’ fabrication, ‘atomically precise manufacturing’, ‘molecular assembly’, ’self-assembly’, ‘nanorobots’, ‘nanofactories’ and so forth. Try describing nanotechnology as a top-down fabrication process and the folks over at Foresight and CRN will tell you what a short-sighted wuss you are. Try describing nanotechnology the Drexlerian way as a bottom-up molecular assembly technology and some scientists will tell you that you are smoking too much of the good stuff.

Continue.

Another good original article from Nanowerk is “Nanotechnology manufacturing key to industrialized countries’ future competitiveness”.

NIST Warms Up to Drexlerian Nanotechnology Monday, Apr 28 2008 

Press release from Eurekalert:

Are nanobots on their way?

US researchers have built a proto-prototype nano assembler

The first real steps towards building a microscopic device that can construct nano machines have been taken by US researchers. Writing in the peer-reviewed publication, International Journal of Nanomanufacturing from Inderscience Publishers, researchers describe an early prototype for a nanoassembler.

In his 1986 book, The Engines of Creation, K Eric Drexler set down the long-term aim of nanotechnology - to create an assembler, a microscopic device, a robot, that could construct yet smaller devices from individual atoms and molecules.

For the last two decades, those researchers who recognized the potential have taken diminutive steps towards such a nanoassembler. Those taking the top-down approach have seen the manipulative power of the atomic force microscope (AFM), a machine that can observe and handle single atoms, as one solution. Those taking the bottom-up approach are using chemistry to build molecular machinery.

However, neither the top-down nor the bottom-up approach is yet to fulfill Drexler’s prophecy of functional nanobots that can construct other machines on a scale of just a few billionths of a meter.

Jason Gorman of the Intelligent Systems Division at the US government’s National Institute of Standards and Technology (NIST) concedes that, “Nanoassembly is extremely challenging.” Yet the rewards could be enormous with the ultimate potential of creating a technology that can construct almost any material from atoms and molecules from super-strong but incredibly lightweight construction materials to a molecular computer or even nanobots that can make other nanobots to solve global problems, such as food, water, and energy shortages.

Gorman and his colleagues at NIST have taken a novel approach to building a nanoassembler and reveal details in a forthcoming issue of the International Journal of Nanomanufacturing. “Our demonstration is still a work in progress,” says Gorman, “you might describe it as a ‘proto-prototype’ for a nanoassembler.”

AFM is the most commonly employed approach for top-down nanomanipulation research, explains Gorman. However, AFM suffers from a number limitations, as the nanoparticles stick together during manipulation and cannot be lifted from the substrate. This means that nanodevices constructed using AFM may be aesthetically pleasing and provide insights into what might be achievable but it cannot build practical nano machines.

The NIST system consists of four Microelectromechanical Systems (MEMS) devices positioned around a centrally located port on a chip into which the starting materials can be placed Each nanomanipulator is composed of positioning mechanism with an attached nanoprobe. By simultaneously controlling the position of each of these nanoprobes, the team can use them to cooperatively assemble a complex structure on a very small scale. “If successful, this project will result in an on-chip nanomanufacturing system that would be the first of its kind,” says Gorman.

“Our micro-scale nanoassembly system is designed for real-time imaging of the nanomanipulation procedures using a scanning electron microscope,” explains Gorman, “and multiple nanoprobes can be used to grasp nanostructures in a cooperative manner to enable complex assembly operations.” Importantly, once the team has optimized their design they anticipate that nanoassembly systems could be made for around $400 per chip at present costs. This is thousands of times cheaper than macro-scale systems such as the AFM.

Gorman points out that it should be possible to have multiple nanoassemblers working simultaneously to manufacture next generation nanoelectronics. At the moment, his team is interested in developing the platform for scientists and engineers to make cutting edge discoveries in nanotechnology. “Very few effective tools exist for manipulation and assembly at the nano-scale, thereby limiting the growth of this critical field,” he says.

“The work described in the IJNM paper is somewhat preliminary and focuses on the design and characterization of the micro-scale nanomanipulator sub-components,” adds Gorman, “We are currently fabricating a somewhat revised micro-scale nanoassembly system that we believe will be capable of manipulating nanoparticles by the end of the summer,” Gorman says, “We will publishing those results once they are available.”

A Molecular Planetary Gear, Cycling Away Tuesday, Apr 15 2008 

This is a simulation of Drexler and Merkle’s famous molecular planetary gear, featured as an illustration in many articles on molecular nanotechnology. It was created using a beta version of Nanorex’s NanoEngineer-1, an open source molecular modeling program that is scheduled for release in the very near future.

The gear simulation was done by Tom Moore of Machine Phase. Tom’s next project will be to simulate the neon pump from Nanosystems. Work like this is a visually fantastic and technically important intermediary step between design and implementation of nanomachine components.

Researchers today created the first thermal nanomotor ever. This device, powered by changes in temperature, can ferry a payload from one place to another or rotate on its axis like a rotor. Concentrated arrays of nanomotors could provide power densities far in excess of today’s best motors. The difference could be so large that this technology appears like magic to us, at least initially.

CRN Monthly Newsletter: March 2008 Wednesday, Apr 2 2008 

CRN’s monthly newsletter is out. It has some interesting news, like a the creation of a powerful new nanoscale computer, a Palo Alto Weekly cover story on nanotechnology in which CRN Executive Director Mike Treder was extensively quoted, a debate over CRN’s scope, a new TV show on nanotechnology, and a guest essay by Michael Berger, editor-in-chief of the popular Nanowerk site. We also learn that Michio Kaku, a physicist/futurist of which I have long been a fan, is now presenting the concepts of desktop nanofactories, artificial general intelligence, and the Singularity in his Visions of the Future series for the BBC.

Here in 2008, we see these concepts quickly mainstreaming. This trend will continue until the technologies are actually created. Before molecular manufacturing is actually developed, there could be tens of millions of people aware of it and making various business/political/entrepreneurial plans accordingly. If the technology is not regulated intelligently, the early MNT era could resemble a game of Hungry Hungry Hippos. As I currently envision it, it ultimately comes down to, “who can make the most nukes and the most effective and redundant systems for delivering them to their targets?”, and “who can hide the best?”

Nanotechnology Protection Agency (NPA) to Regulate Molecular Assemblers Tuesday, Apr 1 2008 

Fresh news from Nanowerk.com:

“(Nanowerk Spotlight) The newly created U.S. Nanotechnology Protection Agency (NPA) announced today, April 1, 2008, that, effective immediately, all laboratories and production facilities for molecular assemblers (commonly called nanobots) need a special license and have to follow strict guidelines in all research and production facilities that deal with nanoassemblers. At the same time, the NPA declared gray goo a hazardous substance.

The new agency also announced the finalists of its Nanobot Hazard Symbol contest. Hundreds of people from all over the globe participated in the NPA’s competition to design a Nanobot-Hazard Symbol that cautions people to be vigilant in the presence of molecular assemblers. The winning design will be submitted to international standard-setting bodies responsible for hazard characterization and could be used as a label on workroom walls and individual nanobots.”

Managing Magic Monday, Mar 31 2008 

Read Managing Magic by the Center for Responsible Nanotechnology. Here’s how it begins:

“It seems like magic. A small appliance, about the size of a washing machine, that is able to manufacture almost anything. It is called a nanofactory. Fed with simple chemical stocks, this amazing machine breaks down molecules, and then reassembles them into any product you ask for. Packed with nanotechnology and robotics, weighing 200 pounds and standing half as tall as a person, it can produce two tons per day of products. Control is simple: a touch screen selects the type and number of products to produce. It costs very little to operate, just the price of materials fed into it. In one hour, $20 worth of chemicals can be converted into 100 pairs of shoes, or 50 shovels, or 200 cell phones, or even a duplicate nanofactory!”
