Pompous and full of air really sums it up well. As such I usually have to completely ignore and rework generated README / code comments.

Is this just an elaborate scheme to increase in/out token churn or are we hitting some kind of LLM limitations I wonder?

I'm a fiction writer. The way you make AI better at writing prose is the same way you make a fiction writer better at writing prose...

That's it. There are no shortcuts to good prose, except perhaps paying a ghost writer.

What is your goal? What are you trying to have it generate that is not more appropriate for you to write yourself?
