It will take a while to realize all they're watching is ads. Arguably influencers were ads too, but they were still humans acting and reacting. Now you get full ad experience end-to-end just in shape of a human, where real humans will be skipped.

AI is just leeching off that credibility now, but how long will it hold up?
Do you think those influencers spend a single second reading the comments/private messages wankers send them? Unless they pay of course.
