Gringely in War of Worlds: The Human Side of Moore’s Law explained:
Andy Hertzfeld said Google is the best tool for an aging programmer because it remembers when we cannot. Dave Winer, back in 1996, came to the conclusion that it was better to bookmark information than to cut and paste it. I'm sure today Dave wouldn't bother with the bookmark and would simply search from scratch to get the most relevant result. Both men point to the idea that we're moving from a knowledge economy to a search economy, from a kingdom of static values to those that are dynamic. Education still seems to define knowing as more important than being able to find, yet which do you do more of in your work? And what's wrong with crimping a paragraph here or there from Cringely if it shows you understand the topic?
This is, of course, a huge threat to the education establishment, which tends to have a very deterministic view of how knowledge and accomplishment are obtained - a view that doesn't work well in the search economy. At the same time K-12 educators are being pulled back by No Child Left Behind, they are being pulled forward (they probably see it as pulled askew) by kids abetted by their high-tech Generation Y (yes, we're getting well into Y) parents who are using their Ward Cleaver power not to maintain the status quo but to challenge it.
With this philosophical view in mind, I think about knowledge as the snapshot which freezes the dynamic process of searching.
