OK, but please don't do what pg did a year or so ago and dismiss anyone who wrote "delve" as AI writing. I've been using "delve" in speech for 15+ years. It's just a question where and how one learns their English.
In any case, it's possible to misuse, abuse, or overuse words like "delve", but to think that the the mere use of "delve" screams "AI-generated"...well, there are some dark tunnels that perhaps such people should delve less into.
It may simply be glazing. If you ask it to estimate your IQ (if it complies), it will likely say >130 regardless of what you actually wrote. RLHF taught it that users like being praised.
