Unfortunately HN is just another algorithm. It roughly aligns with what I already see on my youtube but includes some terribly old videos and a mix of videos from creators I'm currently subscribed to and channels I know I never want to watch again like Joe Rogan, Sabine Hossenfelder, Lex Fridman etc. This is indeed a HN video site and I hate it lol.

The youtube video recommendation algorithm isn't that bad if you're careful which videos you watch. Sometimes you'll take a risk on a video and it'll punish you with a week of similar videos though.
