That doesn't make intuitive sense to me. Surely even fast ems living in cheap real estate will still have plenty (millions? billions?) of people to talk to in real time, even if they have fewer people to talk to compared to those living in prime real estate? Given that running slower has significant costs (you have to pay the same storage costs as faster ems but can do less work, not being able to accumulate experience/knowledge as fast as others and losing competitive edge as a result) I don't see how it's worth those costs just to have more potential people to talk to.

Also, if you're assuming that it's fairly cheap to speed up and slow down emulations, which you apparently are, why don't they run at a fast speed normally and only slow down when they need to talk to distant others with low subjective latency, which may be pretty rare?
