The first draft is too long. The second loses the point you were making. By the fourth you have stopped judging whether it is good and started judging whether you are done.

AI can produce a version instantly, which is not the same as producing the right one. Left alone it pads, hedges, and turns three clear sentences into six confident-sounding ones.

What actually helps is a routine: draft it, make it scannable, edit it deliberately, then check how it will land before it goes out.
