People who work the most with these bots are going to be the researchers whose job it is to churn out this stuff, so they're going to become acclimated to the style, stop noticing the things that stick out, and they'll also be the most likely to accept an AI revision as "yes, that means what I originally wrote and looks good."

Those turns of phrase and the structure underneath the text become tell-tales for AI authorship. I see all sorts of politicians and pundits thinking they're getting away with AI writing, or ghost-writing at best, but it's not even really that hard to see the difference. Just like I can read a page and tell it's Brandon Sanderson, or Patrick Rothfuss, or Douglas Adams, or the "style" of those writers.

Hopefully the AI employees are being diligent about making sure their ideas remain intact. If their training processes start allowing unwanted transformations of source ideas as a side-effect, then the whole rewriting/editing pipeline use case becomes a lot more iffy.
