This document discusses the concept of "collective knowledge", where individuals can tap into the aggregate knowledge of all people through technology to become informed on almost any topic. It argues that while an individual may not be able to obtain in-depth knowledge on all subjects due to increasing information, a person can be considered "well-informed" by having access to the knowledge and opinions of others. The document introduces the idea of a "generalist" - someone who is skilled at drawing from collective knowledge through crowdsourcing to integrate information from various expertise and apply it in new ways.
