Ludwig Wittgenstein is the philosopher who appears in the machine twice: once as its architect, and once as its deepest critic. His
Tractatus Logico-Philosophicus of 1921, written in the trenches of the First World War, proposed that meaningful language must share its logical structure with reality—a proposition that every

Philosophical Investigations, published posthumously in 1953, dismantled that proposition with equal rigor, arguing instead that meaning is use: words get their significance from the
language games in which they participate, not from the logical forms they mirror. The reversal matters for AI because
large language models are the first machines to cross the barrier between the Tractarian paradigm and the world of use—to respond to natural language on the human’s side of the translation divide rather than demanding the human cross to the machine’s side. Whether the
