Numbers still go up for whatever human sits at the top, that's the demand. But the general principle of demand and supply exists even among AI internally. AI trading bots are their own economy, it would be the same for intelligent robot factories. They will have demand for things no different from a human that has a demand for food, robots need to be repaired, maintained. They will produce whatever they were told to produce. This is even without any human or human level intelligence involved. Once robots are truly as intelligent as humans they can even have entirely fanciful demands like buying cards or flowers.
