In primitive economies, there is little or no specialization of the labor force. Everyone has to farm, raise kids, gather herbs, fight, heal wounds, entertain, carry & transmit knowledge, transport, do logistics, cook, make shelter, etc. This is necessary just to survive. There are essentially no silos in this economy; everyone is more or less on the same page, knowledge-wise.
On the other end of the spectrum, we have an extremely specialized society with lots of vertical occupations. Someone can make a living doing only one thing. Examples might be organic blueberry farmer, special needs kindergarten teacher, chemical researcher, Navy SEAL, hand surgeon, stand-up comedian, Phd, bike messenger, operations manager, sushi chef, architect, etc. Each one of these can trade their work for wealth that rivals that of the King of France in the 17th century (in some way).
This economy is extremely silofied - its drawback is that it becomes insular and cross-talk becomes more and more difficult. The reign of tunnel-sighted experts ensues.
This situation cries out for a return of generalists. People who can understand a little bit of everything and make new connections. People who can synthesize. People who grok enough of the entire tech stack to utilize experts like instruments and create a bigger picture.
How do we become Type 2 generalists?
