If mission critical applications (military, automotive, aerospace) are using older chips, and smartphones/computers are using the latest, then everything else is using chips between those two extremes... computer peripherals, office machines, toys, audio/video systems, communication equipment, lights, HVAC, anything rechargeable. The list is massive, you name an industry and they will probably be buying 4nm over the next couple decades.
