That's only because the supercomputer was designed around making it as good for the 'normal' person as possible. Sure it can do so so much more...but the user does not need to know a damn thing about how it works under the hood to use it. Even just making a note with an iPhone requires nearly every last stack of technology invented by man so that the user pressed 'notes' and taps letters on the screen. Custom silicon, 5G & server farms (for cloud backup to prevent knowing about physical storage), 1600nit OLED displays, advanced battery tech...all of it..for those letters to be there when you come back. Knowing a billion little things about computers to use them was always the key problem just like how you are not expected to wire up your lights and configure a circuit box every night in your home.
