Agreed, YouTube homepage and recommendations have been garbage for YEARS.
Since around 2018, to my recollection. I just keep getting the same crap recommendations day after day. It's like, dude, you've suggested the same random clip from Mask of Zorro to me for GOD KNOWS WHAT REASON to me for the past several months, and I haven't clicked on it once. Don't think it's time to generate some fresh recs that might induce me, as a user, to click and watch stuff?
