" 'STET' is presented as an excerpt from a textbook of the future that discusses artificially intelligent vehicles. The main body of the story is a single paragraph, written in dry academic-speak and citing such fictional volumes as Magda Sheenan’s 2023 study 'A Unified Theory of Autonomous Conscience and Vehicular Awareness of Humanity as Compiled from Observations of Artificial Intelligence Behavior in Decision Matrices'. But the real story occurs in the set of footnotes that accompany the lone paragraph, citing further documents from this future era."
