That's not really the point of recommendations though. You don't know whether you want things you don't yet know about, and that's what recommendations solve for.
Discovering new stuff happened way before Google and YouTube. I hear from something that looks interesting, note it down and sometimes later I may read or watch about it.
Why would you want an algorithm to feed what you should watch, like if you were soullessly ‘consuming’ video ? This is saddening.
I can recommend pocket tube extension. You can create subscription groups and assign different channels to different groups. It doesn't require user to be signed in to work.
I use freetube app. It let you subscribe to channels and then show you these channel’s latest videos.
Extremely simple, no « recommendations » (I’m old enough to know what I want), and you cut back on Google ever going algorithm change.
