I wish we could go back; A lot of googles UI/UX is based on the next billion users experiences. I'm unsure how much influence this has on a day to day design choices they make. My experience right now on a 1440p monitor is 5 visible videos, 2 video ads, a ton of tags that I can't turn off for finding videos.
There are a ton of great UI/UX choices they've done over the years too; I just wish we had more options as a users.
