How do you account for such wetware limitations as evidenced by 'dunbar's number'
For those who don't know. Dunbar's number is the cognitive limit of those who we can think of as 'us'. Beyond that number others are thought of as 'them'.
Dunbar's number is individually variable but is approximately one hundred and fifty.
I have not taken into account Dunbar's proposed limit to how many stable relationships can be maintained by a person, while having a mental model of how each person relates to one another. I can only speculate that with the technology to instantaneously communicate directly via thought, and have a vastly expanded memory through a collective consciousness' distributed computational network, that this social stability number would be vastly increased, due to the improvement in communication efficiency, and telepathic retrieval of their memories and thoughts.
Additionally, I don't believe that Dunbar's number is intended to limit the amount of people that can be considered "Us" vs. "Them". There are much larger groups than 150 people in which each member considers all others to be within their "In" group, and treats them with an "Us" disposition. It instead limits the amount of people an individual can have a stable relationship with, and have an understanding of how all these 150 people interrelate. Thanks for your question.
