Wow I felt this post and trust me I am never asking the question! I work in a job where people make "creative" proposals (we say pitches or decks) to me almost every day. The length and word count has exploded. I can't say for sure that it is AI in a case by case basis, but I often suspect it.

It used to be when I got something boring a person wrote I felt obligated to read it. Now I am not sure what to do.
