There is a very large installed base of machines running on QNX, including medical equipment, radio communications, railway switches, automotive modules, etc. Most manufacturers are upgrading in small steps and absolutely do not want to start from scratch with their software layer. Most manufacturers are upgrading in small steps and have no desire to start from scratch with their software layer. At best, they will add a touch screen, an arm processor and an Android system, but only for the interface. The critical parts will remain under QNX. The same is true for VxWorks, a large proportion of industrial PLCs, electrical networks, water and sewage systems depend on VxWorks. QNX and VxWorks are omnipresent but invisible systems.
