I’m not a YouTube commenter, so I don’t have a horse in this race, but it seems like Google is in a very good position to know if a commenter is AI or not. It is very likely that their YouTube account is tied to a Gmail account… they know if that’s being used by a person or not.
Google’s unwillingness to tackle the comment problems has been a problem for years, long before AI. I recall seeing some videos on some scripts a guy wrote to flag and filter spam and bots on YouTube comments. Something Google could and should have done a long time ago. If they have done anything at all recently, it’s been due to public shaming from top creators on the platform.
YT comments were never a good place, but it's interesting to see this shift now its hit the masses
And interesting that no ones commenting about the robotic AI voice over... Instead pointing finger's at each other like the spiderman meme.
