Most humans would have nothing to say to an OS. I am a software engineer and most of the time I function many levels of abstraction away from the OS. Most of my work doesn't even run on the same OS I work in, and when it runs, it talks to an OS that's not even running on an actual computer, but a construct that looks like a computer, but is entirely made up by a hypervisor.
