I don't know about others, but I feel every piece of writing has 2 aspects in the body.

• What it's trying to communicate (purpose of the text)
• How it's communicated (soul of the text/author's originality)

Especially for those who write stories and articles.
Someone who has been reading a specific author's works, would know the author's flows, his habits when writing, sense of humour and how he presents it in the works.

Although once that said work us input in an AI, the soul is bled out. Just the purpose of the text is put in an upfront manner.

That is a major red flag that there's something wrong with the writing and immediately I start questioning the originality of the post.
