Fun fact: operating systems were originally programs intended to replace most of the work of a human job description, that of computer operator.

Computers were first marketed into replacing the work of humans that had a job called "computer" (what spreadsheets finally did)... Operating systems were create to replace computer operators (what they didn't)... For a while some people called compilers "automatic programmers".

The marketing and management of IT always had this fixation with replacing people. It always has been the wrong answer and the real value always came from making people better.
