Diamond Age Approaching?
CosmicDreams writes "The CRN (Center for Responsible Nanotechnology) reports that nanofactories (like the ones that were installed in every home in Neal Stephenson's Diamond Age) will arrive "almost certainly within 20 years". In short they claim that molecular nanotechnology manufacturing will solve many of the world's problems, catalyze a technologic revolution, and start the greatest arms race we've ever seen. They conclude the risks are so great that we should discuss how to deal with this technology so that we don't kill each other when it arrives."
You must have been reading an abridged version. The nanites where built from carbon due to its abundance and tenselary strength compared to its weight. The Vitorians pulled their material out of the water supply, relying on the impurities that the rest of socity intoruced into it. Most of the nanites used clockwork or RF transmited power (a filiment that vibrates when exposed to certain frequencies of radio waves, same place that RFID tags get their juice).

First of all, I'd like to point out the article doesn't make any mention of the substantive amount of energy one of these molecular assemblers would undoubtedly require. If I understand the science even remotely, will it not take energy to break and form atomic bonds that are not naturally occuring? I understand chemical means can be used, but those chemicals need to be manufactured as well. Ignoring such a huge part of the problem doesn't give this article much credibility. Does it matter how far we push technology if we don't have the means to power it?
Aside from that, I can't say I'm overly impressed by the source of the article. The CRN FAQ doesn't inspire much confidence. The two directors have a single undergrad degree between them. I appreciate their enthusiasm in promoting the discussion of nanotechnology and its implications, but I think I'd take it a bit more seriously from a more credible source.
It was an interesting read, but sounded more like wishful thinking from a sci-fi fan than from someone who has a grasp of all the issues that factor into such a huge leap forward for technology.
I work in nanotechnology, and while it might be possible that in 20 years the world will have gone to hell, I highly dount it will be because of this work that no one is doing. The actual work being done in nanotech, is another matter.
These guys make molecular manufacturing sound easy. I'd like to see them try it! None of this is easy, and I would say most of us think molecular manufacturing isn't even possible. The set up described in Drexler's book is not attainable. There are no big names in nanotechnology working on molecular manufacturing, but plenty working on lots of other things.
There is more than enough to be worried about with what is ACTUALLY being done with nanotechnology. It's insulting to those of us in the field, that our research on gas detectors, bio-electronics, nerve regerneration, nanometer transistors, pathogen detectors and drug delivery is deemed so umimportant that it's not even worth talking about. Moreover, there are tremendous issues involved in those projects, which no one is talking about. Any warning about ACTUAL dangers in nanotechnology is being drowned out by ignorant shrills simply seeking the spotlight.
We need a debate on what sensitive explosives sensors are going to do not only for security, but for farmers, scientests and anyone who works around incriminating chemicals. I don't want to be taken in for questioning every time I board a plane. We need to talk about what happens with illegal drugs and steroids when drugs can be delivered to a specific organ and leave the rest of the body largely unaffected. We need to talk about what it really means for education and health when computers are small enough to fit inside the body. The reason I read slashdot is because every once in a while these things come up here. There are plenty of large moral issues literally around the corner, but almost no one is paying attention! Live in the present, it is a fascinating time, and we have many, many unanswered questions.
Debating how to prevent a fictional future arms race depending on a scientific advance many scientests doing the work don't believe will happen in our lifetimes is plain stupid in comparison.
To be fair, I think molecular manufacturing WILL be seen in our lifetime, but it will not be cheap, nor easy, nor fast. Go ahead and calculate how long it will take to make one kilogram of something at 1000000 atoms a second, it's around 1 trillion years. Plain old wet chemistry (aka "bottom up nanotechnology") still has a lot of time and use left. For the first 10 or 20 years molecular manufacturing is around no one will know what to do with it because it will not be this holy grail the media has worked it into. This is based on the history of science, from the steam engine to microscopes capable of atomic resolution. We've always set our sights on these goals, only to be surprised at their implimentation. It's always taken the big breakthroughs a decade or two to get used.
