Too late, YouTube is already infested. Once you notice it you can't unsee it. I would come across a video talking about, say, an anime. All it does is summarize a movie or episode or season. And the voice is crazy obviously just AI generated. The script and whole video are probably AI generated too. Once I noticed that, I did a YouTube search for the same title of the video and you can find like another dozen videos with the same title of various lengths from different channels. Worse of all they have hundreds of thousands of views if not more and _seemingly_ human interactions in the comments. Yet nobody pointing out the obvious AI-ness of it all. Maybe they delete those comments? I dunno. The whole thing is just utterly bizarre. All I can say maybe is just downvote, flag, report any videos or channels like that you see.
As the article says, this policy only applies to content that appears realistic, so it doesn't apply to the videos you're talking about. The videos you're talking about are just a problem for the recommender system.
Sadly I'm one of these peeps that watch the AI gennd content.
The no nonsense of these ai generated content is what gives them the views.
Alot of content on youtuber have people speaking really slowly so that they can fill the required airgap for 'ads' to show.
2x speed works well for the slow speakers as well as with the ai genned content. Many of the 'scripts' they use are actually chinese/korean/japanese translated novels/manga that gets passed the content matching with image movements as well as not even saying the name of the thing they are referencing.
The biggest milestone youtube has reached is they have now determined an email address to send all the horse shit DMCA take-down notices to, when AI does insane things like fair use, or simply naming a product in a bad review.
"Whew, we got the important stuff addressed".
-YouTube probably.
