re: Jargonmeisters
There are also engineers who use jargon when it isn't necessary in order to confuse you or, more often, to make themselves sound more essential.
Some architects, too (Steve G., this does not mean you, but you know the kind I mean...) - not merely to make themselves sound more essential, but more "artistic". You can find their siblings working in interior design, and their lesser kin selling furniture and decor.
