Other way around, actually; C was one of several languages proposed to model UNIX without having to write assembly on every line, and has steadily increased in abstraction. Today, C is specified relative to a high-level abstract machine and doesn’t really resemble any modern processing units’ capabilities.

Nailed it. I think about this a lot: a sysadmin is basically a manager of dozens, hundreds, or even thousands of computers. But management is a poor way of orchestrating human labor; small teams usually operate better without management. So, is there a better way to administer computer systems as well?
