A related empirical data point is that we already see strong light cone effects in electronic markets. The machine decision speeds are so fast that it is not possible to usefully communicate with similarly fast machines outside of a radius of some small number of kilometers because the state of reality at one machine changes faster than it can propagate that information to another due to speed of light limitations. The diminishing ability to influence decisions as a function of distance raises questions about the relevancy of most long haul communication between AGI-like systems.

This is also related to another computer phenomenon where it is becoming cheaper to duplicate computation than to transmit the result of one computation.

Good points. Looking at how the effect is already present in high speed digital trading makes it more immediately relevant, and perhaps we could generalize from some of those lessons for futures dominated by high speed intelligences.

Yes, this is a related divergent effect. The idea of copying the internet into local caches to reduce latency is an example.
