"AI falls under the category of auto-generated content, which could lead to a manual penalty.

However, Google's systems may lack the ability to detect AI generated content without the assistance of human reviewers."

Do they have the ability to detect it WITH human review? And if a human can't detect it, is there anything wrong with it?

Again, this is one of the Google algorithm biases that shows how far we are from having any meaningful way to judge quality. If a massive army of writers turns out more crappy copycat articles and an AI turns out something worth reading...

I'm pretty sure there's a previous statement from Mueller where he says it's okay as long as an editor checks it for accuracy and grammar, that kind of thing.

What I would like to see about this statement is if represents a change from his previous outlook on the matter or if it's just a narrowly focused statement wrt to unedited AI content.

> okay as long as an editor checks it

That makes sense since many legit sports articles are said to be autogen.
