I only skimmed so far, but this quote stuck out:
"Programming is fundamentally a way to save human labor, and that includes our own labor."
I'm continually amazed at how many software engineers seem to miss this point.
I will also add the further caveat for anyone else who arrives here that this was written in stolen hours in the last two weeks, and specifically because the page of 'Assumed Knowledge' referred to in the introduction seems to have been the only instruction in the shell given at Epicodus' Intro to Programming. I'll never love Bash as a programming language, but given that it's a tool developers use every day, I do think there's a certain minimum amount of knowledge required to use it well.
