I wonder how many people it takes to enable the production of one IC. From absolute raw materials to device ready to place into a product. Machines with parts made using other machines and so on. Including the parts and processes and people's experience operating across all of it. It would be interesting to see this whole thing mapped out. It seems to me that this might be helpful in understanding which parts of this ecosystem might be low hanging fruit.
