Kevin Kelly defines “technology” on his blog:

“I want to suggest a theory for technology, a framework that might provide a logic and context for this parade of new things in our lives. But I have to start with the fact that we have a warped idea of what technology is. A lot of us tend to think that technology is ‘anything that was invented after you were born.’ Or technology is: ‘anything that doesn’t work yet.’ As if only the new is what we are talking about.

But of course technology includes old inventions, like clocks and levers, and ancient materials that work very well, like concrete and bricks. The bulk of technology in our lives was invented long before we were born. Ordinary technology also contains intangible ‘stuff’ that we usually don’t see such as calendars, bookkeeping principles, law, and software. It includes large complex things like social organizations and cities. Technology is all this, the old, the invisible, the large and the new — the accumulated usefulness that our minds invent.”
