It was management expert Peter Drucker who first introduced us to the concept of knowledge workers, whom he argued used thinking, creativity, pattern recognition, intellectual reasoning, and general knowledge to expand the resources available to an organization. 

In the sixty years since Drucker coined the term, the information age has expanded the pool of knowledge available and ratcheted up the speed at which decisions need to be made against the information at hand. Given this new landscape, continuing to view knowledge work as an economic principle based on resources seems misguided. Rather, we argue that our focus must turn biological, psychological, and social and begin to look at the world’s most untapped resource — the human brain.
