I suspect you need quite narrow tastes for the algorithm to be able to figure it out, like if you watch sports videos it's probably just gonna keep feeding your sports videos forever, because that's trivially easy and works.

i know i've had times were i got a bit too lax with the kinds of minecraft videos i watched and i could feel the algorithm desperately wanting to feed me standard clickbaity shouty videos, and its disappointment when i recoiled from that.
