The best technology is the one you don't think of as technology? Jim Manzi thinks so:

What’s so funny about this is that CFL proponents (or more precisely, proponents of laws that would make it illegal for you to use incandescent bulbs in your house) often refer to “inefficient incandescent technology that has barely changed since the invention of the tungsten filament nearly a century ago.” This profoundly misunderstands technology. The best technologies last hundreds or thousands of years, and become so much a part of the built environment that we don’t even think of them as technologies anymore: books, stone houses, woven shirts, fire. The fact that incandescent bulbs have lasted as long as they have and that a law is required to make people give them up probably indicates that it is a great technology.
