AI is only as good as the human behind it. I can always tell when someone is written by AI—it sounds wooden and dead. Write your own book.
Oh, I am definitely NOT using AI for the actual writing. Like you, I find AI is simply uncreative, flat, and forced. I originally had some fear of AI. No more.
I am, however, using it for suggestions on how to improve my writing. It seems to work fairly well in that regard.
AI is only an assimilation of information that is sorted in various ways. It can not duplicate human brain intuition or cognitive ability nor can it interject emotion or feelings.
The internet search ability is it only AI.
It is big deal, other peoples work, but filter through it well, after all it brought us the fake flu scam.
