TikTok is the only recommender I've heard actually work for people. Netflix is tuned for what they want to show people, not what people want to watch. Algorithmic timelines generally aren't popular with users though.
(Although a lot of "recommendation algorithms" are actually spam fighting, not engagement promoting.)

Depends on how well they work, as you say, TikTok is a big one where I doubt many people want their feed in a chronological manner instead. Technical people especially seem to dislike algorithmic feeds but for the layperson, they don't really mind it (indeed, they don't even think about it at all, based on personal experience some of the people I've talked to don't even know that chronological feeds are even a thing).
