I am writing this blog post on a train that moves quickly along the rails, with intermittent stops in small to smallish cities. I am writing this blog post on a laptop, and a while ago I checked Wikipedia concerning Philip K. Dick (in connection with the recently published TV show The Man in the High Castle). As you can see, I am surrounded by many a technical artefact. Actually, every one of us experiences the same immersion: technical artefacts are prevalent to the degree that it is actually quite hard to put a finger on what they actually are. There are easy cases, such as a train, but what about a Wikipedia page? Is such a page a technical artefact, or rather a special configuration of supporting technical artefacts, such as the Wikipedia server I accessed and the connecting Internet?
