The South Africans have a beautiful philosophy called Ubuntu, which translates as "I am what I am because of who we all are." This is a perfect way to think about the way a brain develops, influenced by its surrounding people and experiences. It's also how we should think about the way the Internet is developing, and about the way our choices in how we use technology are shaping this global brain. For both the brain and the Internet, networks are always binding us in new ways and changing our understanding of who we are and how we perceive the world. If we believe that the Internet comparatively is in the same critical stage of early development as a child, making as many connections as possible, then we need to be mindful of how we're building its foundation.
