On the mobile app, they show "pill buttons" for your detected interests across the top and you can click on them to filter those topics specifically. So they have put some nominal work into supporting orthogonal interests. The problem for me is that it just doesn't work very well. First, it's hidden deeply in the UI. Second, the topics are self-detected (poorly) and you have no way to edit them. Third, they seem to act as simple filters of your feed, not a way to access different subsets of content. I'm sure the root of the problem is that lots of smart people at YouTube probably understand this frustration and want to make this better, but building filtering tools doesn't improve overall user engagement metrics and doesn't get anyone promoted, so no one does. But what does improve overall engagement? Recommending streamer bro meme videos in the chance that a kid might get hooked and watch thousands more of them.
