I really have never understood this. Short form videos are no more or less interesting to me than any other. I also do not find the YouTube main page very compelling, and rarely follow the things that are suggested at the ends of videos. I certainly do not feel ill if I forget to use YouTube for a week.
The trouble with short form videos is that they lower your attention span if you are continuously watching them over a period of time, which then leaves you not wanting to watch the long-form videos any more, or do anything that requires concentration - leaving you to be a doomscrolling zombie.
I've been using YouTube for a long time, and the suggestions are usually things I find interesting.
