The New York Time has an essay by Steven Johnson:
2005 may be the year when tools for thought become a reality for people who manipulate words for a living, thanks to the release of nearly a dozen new programs all aiming to do for your personal information what Google has done for the Internet. These programs all work in slightly different ways, but they share two remarkable properties: the ability to interpret the meaning of text documents; and the ability to filter through thousands of documents in the time it takes to have a sip of coffee. Put those two elements together and you have a tool that will have as significant an impact on the way writers work as the original word processors did.
For the past three years, I’ve been using tools comparable to the new ones hitting the market, so I have extensive firsthand experience with the way the software changes the creative process. (I have used a custom-designed application, created by the programmer Maciej Ceglowski at the National Institute for Technology and Liberal Education, and now use an off-the-shelf program called DEVONthink.) The raw material the software relies on is an archive of my writings and notes, plus a few thousand choice quotes from books I have read over the past decade: an archive, in other words, of all my old ideas, and the ideas that have influenced me.
Having all this information available at my fingerprints does more than help me find my notes faster. Yes, when I’m trying to track down an article I wrote many years ago, it’s now much easier to retrieve. But the qualitative change lies elsewhere: in finding documents I’ve forgotten about altogether, documents that I didn’t know I was looking for.
What does this mean in practice? Consider how I used the tool in writing my last book, which revolved around the latest developments in brain science. I would write a paragraph that addressed the human brain’s remarkable facility for interpreting facial expressions. I’d then plug that paragraph into the software, and ask it to find other, similar passages in my archive. Instantly, a list of quotes would be returned: some on the neural architecture that triggers facial expressions, others on the evolutionary history of the smile, still others that dealt with the expressiveness of our near relatives, the chimpanzees. Invariably, one or two of these would trigger a new association in my head — I’d forgotten about the chimpanzee connection — and I’d select that quote, and ask the software to find a new batch of documents similar to it. Before long a larger idea had taken shape in my head, built out of the trail of associations the machine had assembled for me.
