I agree with this. That's how I use AI's writing -- to enhance my own writing.
I write a first draft, AI revises it, I rework a second draft, AI revises it, then I curate a final draft. That's my typical AI-enhanced writing process. AI can even provide multiple variations of each revision, from which I incorporate the best content from each back into my own writing.
The combination of my ability to pick what's good and AI's ability to quickly come up with numerous options creates a better result than I could on my own with a similar amount of effort.
