"Humans evolved to be in groups of about 30-100 people who they knew their whole lives"
When did this happen? A female chimpanzee will grow up in a tribe of 30 to 150 and then at adolescence move to another tribe of 30 to 150, and occasionally, after a tribal war, end up in another tribe of 30 to 150. Each tribe was typically surrounded by 1 to 5 other tribes of 30 to 150, and of course the chimpanzees had to keep track of their enemies, just as any species that engages in territory and warfare will have to keep track of what territory is held by who. So the average chimp has to keep track of several hundred other chimps, as well as tigers, gazelles, monkeys, etc. It's a complex situation.
When you say humans track 30 to 100 people, do you mean 10 million years ago? Because you can't mean homo sapiens? I personally know more than 12,000 people:
You are right, I am confused. How would I keep track of someone if I don't know them? This includes not just people but all of the animals that I interact with. My mom used to have a bird feeder and I spent countless hours watching the birds. I got to know several dozen as individuals, I was aware of their injuries and their style of eating (timid, brave, quick, slow). How might I keep track of them without knowing them? Perhaps you might consider that your ideas on this subject are a bit muddy?
Also, you misread the original comment when they wrote "their whole lives" -- they are asserting people never know more than that 30 to 100 people, an assertion which is absurd.
> You are right, I am confused. How would I keep track of someone if I don't know them?
What are you talking about? Just because you have to know someone to keep track of them doesn't mean everyone you encounter you can track or care about.
