I think this is a somewhat "over engineered" approach. I have a range of interests and don't feel any need to have multiple profiles. YouTube is quite good at understanding what I want. One way this manifests for example is that I use YouTube at work to listen to concerts in the background while I work, but at home I will almost never listen to music or concerts on YouTube as I'm mostly using it like a TV. Despite the same YouTube profile, my work machine gets mostly concerts in the home feed, and my home machine gets mostly other stuff. There's just enough crossover that I can get into either style of watching on either machine though, and in the rare cases where I have done, YouTube seems to react quickly.
