honestly I hope not long. I could not care less about what random people like or dislike, what they comment on videos, or anything else. what's next is a great feature since I put on a song and it plays something similar next. a TV channel is the perfect use case for youtube, where instead of selecting a channel like on TV, you select a channel by type of video you first play.

sidenote: I had no idea youtube had likes or dislikes until I read this post. I have however, used youtube to, you know, play a video and look at that video. I have zero idea about other components of the site, outside of the video playing, and a list of what's next. I've used youtube since before it was owned by google.

now I don't know if I'm the target demographic, but it seems to me like youtube is doing the right thing and focusing on it's core feature while removing screen spam. and w/ ublock, I haven't seen an ad on there in a decade.
