I feel silly explaining this as if it's a new thing, but there's a concept in social organization called "specialization" in which societies advance because some people decide to focus on growing food while some people focus on defending against threats and other people focus on building better tools, etc. A society which has a rich social contract which facilitates a high degree of specialization is usually more virile than a subsistence economy in which every individual has all the responsibilities: food gathering, defense, toolmaking, and more.
I wonder if people are forgetting this when they herald the arrival of a new era in which everyone is the maker of their own tools...
