For me it's the opposite, for some reason practically all Youtube recommendations outside of the subscribed channels are completely useless and I would never watch them. There are only few exceptions. It's not that the recommendations are toxic, they are just extremely bad. The algorithm doesn't seem to be able to learn what interests me. My suspicion is that this is so because I have a lot of diverging interests that change from month to month. Still, this does not explain why Youtube keeps recommending channels and topics even when I never watch them.
