“Both personbytes and firmbytes show that our ability to accumulate large volumes of knowledge and knowhow is packaged in a nested structure in which what we consider to be a network at one scale becomes a node in the next. Networks of neurons become nodes when we abstract them as people, and networks of people become nodes when we abstract them as networks of firms. The bottom line is that accumulating large volumes of knowledge and knowhow is difficult because it requires evolving the networks that embody that knowledge and knowhow”
