A "British anthropologist says he’s determined that cognitively, we can only handle 150 real friends at a time. Even when it comes to Facebook and other social networks, Robin Dunbar says, we only truly maintain communication with the magic 150. “Dunbar’s number,” according to the Times of London, originated in the 1990s when Dunbar’s research indicated that “the size of our neocortex — the part of the brain used for conscious thought and language — limits us to managing social circles of around 150 friends, no matter how sociable we are.”"
While technologies can take us further than ever before, it is always humanity that creates meaning. Words have meaning because we speak them, not because they exist. Even the most advanced AI algorithms today come down to pattern matching. They don’t know why we react differently to a story about earthquakes in Haiti than we do to a story about vacations in Haiti.
Consider web search: you have some question in your head, and what you have to do is turn that question into keywords, find a browser, search through results, and extract information. It’s as though we’ve forgotten that a question is an invitation to a human experience. The amount of information in peoples’ heads dwarfs the amount of information in computers. So they started Aardvark — you send it a question, and Aardvark’s job is to find a person who can answer that question. They use AI not to replace people but to help connect people.
