I'm not the person you're replying to but in my experience the YouTube algorithm is quite bad at filling my wish for a variety of topics and tone at all levels. I feel like watching one or two clips from the same channel suddenly floods me with that going forward which is rarely what I want. Personally I have a core set of things I want lots of plus I'd really appreciate brief forays into new topics with similar creators or new creators with similar topics but this feels completely impossible for me on yt.

I think they've jumped the shark and need to give me more control because currently I actively avoid watching videos I think MIGHT be interesting because the risk is too high. This is a terrible position to put your users in both from a specific experience perspective but also in a "how they feel about your product" perspective.

The problem with that is, I have more than one interest. So any algorithm will make a salad out of that and never hit me with what I want. Even if this particular session was about topic X they will still fill it with proposals from yesterday's topic Y, or extrapolate from them to topic Z I don't care, and so on. Mostly useless either way.

There videos which YouTube will very very rarely recommended you, especially if they are not monetised and let’s say critical or opposing the mainstream.
