It is better to be consistent but wrong, than inconsistent but correct.
Consistent and correct might seem ideal, but merely the fact that what is 'correct' is in the eye of the beholder most of the time, making it basically unobtainable.
But being consistent is at least something that is far less subjective.
Platforms like YouTube and TikTok already have almost full control of how the majority of users spend their time on their platforms. They open the app, they immediately get a feed of content algorithmically selected to keep them on the app for as long as possible. They don't need to search, they don't need to think about what they want to watch, they just consume. Fully automated consumption with 0 human effort involved.
Well, almost. There's one last thing remaining: you still need humans to produce the content that you then put on people's feeds. Or rather, needed. Now that the actual production can also be automated, those platforms no longer need to put effort into finding existing human-created content that will keep people watching - they can just generate new, algorithmically perfect content. This is their endgame.
Given these advantages I expect the current "social media" to be replaced with a new one, rather than them pivoting. The next big thing after tiktok might be something that only has generated content, where a last final bit of "social" is taken out of "social media".
