YouTube comments in general are so predictable, for some reason. You've got your classics, like the sex bots and the "Just leaving a comment for the Algorithm". But you can also be sure, for example, that if there's a funny oneliner in a video, that one of the top comments will be a direct quote of that oneliner with nothing added.

I guess, to some degree, it's just the socialization reactions like you might have when watching a movie together. They don't have to be deep and meaningful.
But I almost wish there were separate comment sections, one for the shallow reactions and jerking off the Algorithm, and one for people actually wanting to add something. There's often lots of interesting parts about videos where I'd like to know what others have to say about it, but good luck finding those comments.
