You have raised an excellent point. The issue is not that AI could writes better articles than me. AI can easy product a massive amount of grammatical statements. With the entire never ending production line of text, it could easy use most of my favorite lines. It is like the infinite number of monkeys on typewriters except that monkeys now have spell check, understand the rules of grammar and type faster than me.

And then have another AI searching new writing and flagging my text for plagiarism.

There may be a million ways to write something but I am betting that computers will at least brute force their way to getting the low hanging fruits first.
