The idea
An operating system is the core piece of software managing and controlling the interconnection of hardware and software on a computer — loaded at start-up, and required to operate any computerized device.

Every phone, laptop, and watch in the room booted one before doing anything else.
Where people slip
Core software, not optional middleware.
