ABSTRACT
Humans have used artefacts since the invention of cuneiform writing,
but the complexity of present-day computerised artefacts often create
more problems than they solve. Artefacts can be either tools or
prostheses, and the chapter develops these distinctions. While
artefacts (technical or social) ostensibly are introduced to make life
easier for people, the effect sometimes turn out to be the exact
opposite.
