>I have worked with many developers who believe that whatever they value is obviously the right values and everybody else just don’t get it.

My go-to example of developer hubris is all the language-mangling technology I have to work around everyday, because it's on by default: auto-complete, phrase suggestions, fuzzy searching, etc. I'm perfectly capable of expressing my intent. I don't need a computer to say "well, um, actually I know you really want something else."
