Do you guys think human society is more complex, or less complex, than an individual human brain?
To be honest, I don't know. Complexity is the science of chaos. We are mapping the brain and can actually program computers to mimic thought to a degree. The signal to noise ratio is higher in the brain than society. Society is really pretty simple if you filter out statistically insignificant error. I prefer to think of us as family. After all, we all evolved from the same ancestors. We're just a very dysfunctional family.
A human can only maintain intimate social connections up to 150 people. Also, what happens if I don't want to care for a certain person? What if I want to discriminate in who I give my love and labor to?
