The Tractarian Machine
The
Ludwig Wittgenstein — On AI volume's name for the stored-program computer considered as a philosophical commitment realized in silicon — the
picture theory of meaning made operational.
Alan Turing's 1936 formalization of computation,
John von Neumann's 1945 stored-program architecture, and every computer built since are, read through Wittgenstein's framework, philosophical commitments realized in hardware. They commit to the proposition that meaning is exhausted by formal structure, that understanding a program consists in tracing its operations, that communication
between human and machine must take the form of unambiguous specification. This is the
Tractarian commitment, built in silicon. Every computer ever built, from
ENIAC to the laptop on which these words were composed, embodies it. The
language interface does not remove the Tractarian machine; it layers a new mediation on top of it.

In 1939, Turing sat in a Cambridge lecture hall listening to Wittgenstein discuss the foundations of mathematics. Wittgenstein was already moving beyond the Tractatus, dismantling the assumption that meaning reduces to logical form. Turing was building a career on that assumption, translating it from philosophy into engineering. They argued. Wittgenstein remarked that
