People who have money will always pay a premium for quality.
With regards to writing, if you can create quality information with AI faster than before, you will be more profitable.
If you are going wide, and throwing spaghetti at the wall with crappy writing, you may also be able to generate $1 from a million people vs. $10,000 from 100 people.
AI threatens the middle for sure, and will force all of us to change our strategies.
