The thrust this book lays on global optimum In manufacture was an operational expense.
If knowledge as a patent is used to sell, it is inventory, while knowledge used Investment is inventory, as per this definition and the robots were inventory. The inventory and operational expenses per unit combined, they made profit.

Thisĭefinition helps Alex identify the myth of the efficiencies of the robots, May, at an efficiently low level of inventory, show a net loss being theĭifference between the product cost and material cost of inventory.
