[3] One of the major innovations of the concept of ergodic literature is that it is not medium-specific so long as the medium has the ability to produce an iteration of the text.
Aarseth broke with this basic assumption that the medium was the most important distinction, and argued that the mechanics of texts need not be medium-specific.
"[1]: 179 Cybertext is a subcategory of ergodic literature that Aarseth defines as "texts that involve calculation in their production of scriptons".
[1]: 75 The process of reading printed matter, in contrast, involves "trivial" extranoematic effort, that is, merely moving one's eyes along lines of text and turning pages.
A chat bot such as ELIZA is a cybertext because when the reader types in a sentence, the text-machine actually performs calculations on the fly that generate a textual response.
