I probably need to revisit this (and the references) but I really enjoyed reading Silvio Lorusso’s essay on computer agency and behaviour.

Alan Kay’s pioneering work on interfaces was guided by the idea that the computer should be a medium rather than a vehicle, its function not pre-established (like that of the car or the television) but reformulable by the user (like in the case of paper and clay). For Kay, the computer had to be a general-purpose device. He also elaborated a notion of computer literacy which would include the ability to read the content of a medium (the tools and materials generated by others) but also the ability to write in a medium. Writing on the computer medium would not only include the production of materials, but also of tools. That is for Kay authentic computer literacy: “In print writing, the tools you generate are rhetorical; they demonstrate and convince. In computer writing, the tools you generate are processes; they simulate and decide.”
