Channel Capacity and Impedance
Channel capacity, in
Shannon's information theory, is the maximum rate at which information can be reliably transmitted through a given communication pathway. Channel impedance — a term Moles imported from electrical engineering — is the resistance the channel offers to transmission. The
imagination-to-artifact ratio described in
You On AI is, in Moles's framework, a measure of channel impedance. The medieval cathedral required a channel of enormous impedance — hundreds of workers, decades of labor, immense material resources — to transmit the architect's vision into physical form. The
natural language interface has reduced impedance to near zero for a significant class of creative work. The consequences are both liberating and destabilizing.

Every technological abstraction in the history of computing has reduced channel impedance. Assembly language imposed enormous impedance — the programmer had to think at the level of memory addresses and processor instructions. High-level languages reduced impedance by allowing thought closer to the domain of the problem. Frameworks reduced
