I think you're right (though YT is crazy good and finding what you like imo).

> I would say that the rise of group chats instead is evidence of how social media is failing users. People do want to communicate with a closed group. It's like they say: any organization app has to compete with emailing yourself. Any social media has to compete with a group chat.

This is true, but the truth is that you spend maybe 1 hour (if that) in group chats, while many people spend 4-5 hours a day on Tiktok/IGReels. So the revealed preference is that yes, they want to be connected to their friends via group chats, but they want mindless entertainment a lot more.
