I prefer to call all human inventions technology, because even if a technology is old, it's still serving its purpose. Even if we're taking it for granted.

Plumbing put us all out of the water carrying business. But without it, daily life would be very, very different.

Google's definition of technology is interesting. - the application of scientific knowledge for practical purposes, especially in industry. - machinery and equipment developed from the application of scientific knowledge.

I guess technology is the process of making technology. Pipes are a technology, but most of technology is over.

But it also sounds like technology when a plumber is applying his knowledge of metal and fire and gravity to solve a new problem.
