I've been a professional writer for 15 years (primarily as the technical lead for federal grants and proposals). My educational background includes the University of Virginia and Johns Hopkins. I don't know a single person in my career field or former graduating class who would use any of those words and phrases. Since government agencies require companies to submit proposal responses within a short timeframe and even smaller page limit, editing out "fluff" is actually a six-figure position. No complaints about AI from my end!
