Why did Smalley change his mind?

This submission is of interest given previous comments by Eric Drexler on the politics of nanotech research discussed in July.

MartinBaldan writes "Hi, I'm afraid it's a bit late for this, but I've found a piece of Smalley's previous position on MNT and it was rather opposed to the one he holds now: [1]

"If you could get down to that nanometer level, and craft the object with atomic precision, the power of your ability to control the behavior of this object would become immense."

"Imagine what our world would be like if we really could construct on the dry side, without water and living cells, objects with the degree of atomic perfection that life achieves routinely on the wet side. Imagine for a moment the power of what I like to call the "dry side" of nanotechnology. The list of things you could do with such a technology reads like much of the Christmas Wish List of our civilization."

"But the technologies on this list are in a sense, CHEMISTRY in big, bold type: an atomically precise technology that lets you build elaborate structures on a scale of 1 to 100 nanometers. Structures that can go out do things that are really important – like storing information, switching electrical signals, converting sunlight to electricity, transporting electricity in super-strong cables for thousands of miles without loss, and converting this electricity into stored chemical energy and back again in the batteries and fuel cells of the 21st century, and on and on and on."

"And I am confident that in almost every area the keys to these technologies are going to come when we start learning how to put things together one atom at a time on the nanometer scale.

We've got to learn how to build machines, materials, and devices with the ultimate finesse that life has always used: atom by atom, on the same nanometer scale as the machinery in living cells. But now we've got to learn how to extend this now to the dry world. We need to develop nanotechnology both on the wet and dry sides. We need it urgently to get through these next 50 years. It will be a challenge. But, I am confident we will succeed."

Martin asks:

  • Why did Smalley change his mind so much?
  • Why doesn't he mention the fact that he changed his mind?
  • Why hasn't anyone asked him about it?

By the way, there's a link to this Smalley article in R. Merkle's nanotech website:http://www.zyvex.com/nano/ but it's broken. You are suggested to search the website of Smalley's research group (Center for Nanoscale Science and Technology): http://cnst.rice.edu/ but there's no search option on that website."

    He changed his mind because of two words.

    The Illuminati. I'm not ready to forfeit my life at this time – so that's all I'll say.

    Strange

    I've been wondering about that myself for some time. It's certainly been a dramatic U-Turn for him. He is very hostile to his old position but only seems to offer hand waving arguments and wishy washy metaphores. There's definately something strange going on there. Its almost like a self denial.

    Wired article

    The October 2004 issue of Wired magazine has comments by Smalley in which he describes his change of heart:

    Sitting in his hotel room at June's NanoSummit, Smalley explains that he was once captivated by Drexler's notions. "I was enchanted by Engines of Creation," he says. "I read it in a single sitting, and then I reread it." As late as 1999, he testified to Congress about "what will be possible when we learn to build things at the ultimate level of control, one atom at a time."

    But doubts crept in as Smalley pondered the theory. "For months I said to myself, How could we have missed this? Is it really possible to do chemistry in this way? After a while I thought I saw what might be some problems. The more I thought about it, the more troublesome they appeared. Finally I ended up thinking, it's just hopeless."

    Smalley recalls a meeting he arranged with Drexler at Stanford about a decade ago. "I wanted to talk about the tip," he says, referring to the business end of Drexler's machines. "I love the idea of the assembler. So I tried to drag him into a conversation about the tip, and he stonewalled. It was as if the tip was a job for later."

    Re:Wired article

    A decade ago would be circa 1994. That would have been only slightly after the release of Nanosystems and may have been before the release of the first robust molecular designs for aspects of an assembler arm such as the Fine Motion Controller.

    I think it is clear to a number of people at this point that the tip chemistry is going to be an important issue. (One is going to need a library of structures/reactions that the tip can adopt and engage in.) But enough reactions have been done at both the simulation and experimental levels at this point that it should be clear that these can be developed.

    What has been a "job for later" is an actual atomic scale design for a full assembler system, including the 4-8 million atoms in the arm itself. That is roughly ~1000x the number of atoms in the FMC. But given the high level of redundancy in the structure of an assembler arm the job is probably only 10-100x more complex than the design of the FMC. That is something that could easily be undertaken by either a major national laboratory or a major manufacturing company. My current guess is that the design would require ~25 person-years (perhaps much less if significant software design support were available). While that isn't something an academic chemist would seriously consider it is something that a company like IBM or Boeing or Intel could easily wrap their hands around.
