Spacetime Language Model

A language model with explicit awareness of the spatial and temporal dimensions of language—understanding that words, meanings, and concepts evolve across time and vary across space. Spacetime Language Models wouldn't just process text; they'd track how language changes, how meanings shift, how context matters. They'd be capable of historical linguistics, geographical variation, and diachronic analysis built into their architecture. Language models that know language lives in space and time.

"I asked what 'awful' meant. The spacetime language model didn't just say 'very bad'; it showed how it used to mean 'full of awe,' tracked its evolution over centuries, and noted regional variations in current usage. It knew words have histories and geographies."
