In about 1989 I ran across a gas pump with a credit card reader built into it. I realized that the signal travelling from the pump to a centralized computer system was data, but the signl travelling back too the pump became credit, then money, then commodities as the pump was instructed to dispense gasoline. It can be further generalized that for most flows of data from one machine to another, there is a corresponding flow in a reverse direction, but possibly along a different circuit, of money. I came up with a list of relationships in increasing order of abstraction, going from the concrete basis of Newton's laws of motion, to entropy, to Shannon's information theory, to the equation for the flow of monry in a post-industrial economy. I felt that some might find the last point to be too abstract.
Electronic money allows organizations to do things and immediately sense the results.
The implications of the recent advent of digital currency speeds up the feedback loops that have already existed in the econmy.
