I think in a philosophical sense that is true. However, our wetware is just wired to keep about 100 fellow people close. More than that and relationships seem to become very superficial. Most people only maintain a very small number of close relationships. Those are the "important" ones. Importance is sort of decided naturally, though.

100 seems high. I have heard it's more like 12 to 15.

I think bitexploder is referring to the "Dunbar's number" which is 150.

https://en.wikipedia.org/wiki/Dunbar%27s_number

From the wiki: Dunbar's number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships. By using the average human brain size and extrapolating from the results of primates, he proposed that humans can comfortably maintain only 150 stable relationships.
