A Difference That Makes a Difference
Bateson's precise definition of information: not a substance but a relation — a distinction registered by a system in a way that produces further consequences in that system.
Bateson defined information as 'a difference that makes a difference.' The emphasis falls on the second difference — the making, the consequence, the effect the distinction produces. A tree falls in a forest; if no system registers the fall, the event produces physical change but not information. Information requires a circuit in which the difference is registered and the registration makes a further difference. This definition has direct consequences for AI. The AI is a transducer: it takes differences expressed in natural language and converts them into different kinds of differences — connections not seen, structural clarities that were latent. The transduction is circular, not one-directional. What has changed with current AI is the dimensionality of the transduction — communicative, analytical, creative, memorial, hermeneutic — all expanding simultaneously.

The definition emerges from cybernetic formalism. In classical physics, causation travels through forces and impacts — one billiard ball striking another. In cybernetics
