Algorithmic curated content only works well on video based platforms (to some degree) but not quite on text-based platforms. I think this because of users expectation or need.

While on platforms like Tiktok I basically want to consume content. On twitter my need to share and engage with meaningful content but what I am fed instead is propaganda.

Also, due to the fact that the platform (twitter) has become a lot toxic, most people are unwilling to share their thoughts, which gives room to all the type of contact you don't want to see, including AI geberated content. Plus, the world is so polarised and everyone has an agenda, so the entire social experience/expectation as changed from connecting and sharing experiences to virtue signaling and rage baiting
