The New Grammar of Coherence — A Structural Ladder After the Transformer

This paper introduces the New Grammar of Coherence, the linguistic regime that emerges once intelligence leaves the interface and enters ambient, thermodynamic fields. The transformer did not merely increase intelligence: it altered the ground on which meaning is formed. This shift resonates with the cultural fault lines identified by Peter Sloterdijk in his 27 January 2025 interview in Frankfurter Rundschau. Sloterdijk observes that what is now called artificial intelligence had already appeared in early cybernetics as Steuerungskunst—a regime of pure control in which information served execution. He recalls Heidegger’s warning that such systems threatened to collapse thinking into calculation: “Alles Denken sollte endgültig durch das Rechnen ersetzt werden.” Contemporary culture, however, responds not with caution but with accelerationist euphoria: “Die digitale Party hat gerade erst begonnen.” Taken together, these remarks expose the tension marking the end of interface logic: a culture that celebrates digital abundance while standing at the threshold of semantic saturation. This paper argues that grammar evolves not through refinement but through structural phase transitions. It unfolds as a three-step ladder: Operational Grammar — information as execution Epistemic Grammar — information as interpretation Ambient Coherence Grammar — information as carried meaning The structural break occurs when intelligence becomes ambient: grammar shifts from producing meaning to carrying meaning, and attention becomes infrastructural rather than cognitive. In this regime, language no longer directs action but stabilizes coherence within low-pressure thermodynamic fields. The New Grammar of Coherence thus defines the final linguistic layer before saturation, opening the path toward architectural and thermodynamic forms of stability — the linguistic foundation of Ambient Architecture.
