It's important for manipulating dynamic physical objects. Things tied stronger to wall clock than CPU clock, like rockets flying through the atmosphere and EV motors rotating as car rolls downhill. They don't care about cache hits and branch predictions, so whatever you do with pulsating fuel pressure or flowing back regen electricity better happen predictably on-time than just ASAP off quuees. RTOS offer you that stability in time direction.
