To triumph today, we must now understand new information and complex concepts—what hasn’t been known before and is often more complicated than one person can figure out alone. The 21st century mind is a collective mind where we access what we know in our friends’ and colleagues’ brains. Together we can be smarter and can address ever more challenging problems. What we store in our heads may not be as important as all that we can tap in our networks. Together we are better.
