I don't really think that's how this plays out. Facebook can squeeze people a little longer, but if all you want is entertainment other options seem better. End of the day Facebook's moat is your network, but if it's not useful for keeping up with the people you care about, what's special about it? I see a lot of AI generated stuff on youtube, but the view counts are pretty low, so I don't think most of it is getting much traction (and frankly it's very obvious that it's AI just from thumbnails 99% of the time).
