I find the recommendations genuinely horrible. I only get channels like real life lore, Adam Something etc, with sometimes very shallow takes at politics. And after marking those channels with "I don't want to see this", I get their hundreds of copycats.

I mostly watch channels like Aswath Damodaran, mCoding, etc., which are not related to the contents of the mentioned channels at all, yet their recommendation engine still shows me all this stuff.
