Laugh 3 times at AI
1). AI 'detectors' that use AI to determine if something is AI. AKA "Set a thief to catch a thief".
2). All the technical writing I used to do which had to be 'formal' because the information needed to be presented as accurately as possible, even if those reading it were not capable of understanding proper English. Every bit of that would have triggered a "99% probability of having been written by AI".
3). Only poorly-written paragraphs pass the "not AI" test, despite the fact that AI-generated text is poorly written. Vernacular; yeah, it's a thing. You've probably seen the spell & grammar checkers light up like Christmas trees whenever you write a bit of dialog, eh?
Yes AI would be hilarious - if it weren't actually dangerous in oh-so-many ways.
