CONCEPT
The Limits of My Language Mean the Limits of My World
Wittgenstein’s Tractarian proposition that the boundary of expressible language is the boundary of the thinkable world—and the insight that the AI language interface has expanded both boundaries in one move, without touching the domain that makes the expansion worth anything.
“The limits of my language mean the limits of my world.” This sentence from
the Tractatus is the most quoted sentence in the history of philosophy, and for fifty years it was literally true of computing. The limits of the programmer’s language—the formal language the machine could process—were the limits of the programmer’s computational world. What could be expressed in the formal language could be built; what could not be expressed could not. The boundary of expression was the boundary of capability, and the boundary was enforced every day by the cognitive cost of compressing natural-language intentions into formal specifications. When
large language models crossed the translation barrier in 2025, the proposition’s application changed: the limits of the programmer’s natural language became the limits of her computational world, and natural language is incomparably richer than any formal language. The expansion is real, and the cycle that begins with
