Since the widespread adoption of the printing press, we have been writing with and for machines. However, the ways and the extent to which machines could participate in acts of writing have changed over time. “In Writing” is a project dedicated to defining and investigating writing and to thinking about how the machines we use in the creation, production, and distribution of writing relate to how writing happens and what writing may mean. Functioning at once as a graphical, logical, and poetic sign system, verbal language, which is the medium of representation we most often associate with acts of writing, has unique properties depending on the tools employed for its production and dissemination. In this project, I graphically and discursively investigate the specific functions and affordances of verbal language across four distinct medial environments– handwriting, typewriting, word processing, and JavaScript—in order to explore the shared and divergent processes, products, and rhetorical implications of writing in each.
