It's good at finding things you'd watch, but not necessarily things you should be watching. Ex-youtube employees said that the algorithm is trained to keep you engaged and watching videos, so the recommended videos keep getting more and more extreme. This isn't really an issue with music because it just ends up at more niche artists, but if you watch a political video and keep following its recommendations, eventually you end up wathcing extremist left/right wing propaganda. Sure, it's something you don't mind watching once you get there, but it's not necessarily something you would have wanted to watch before the youtube algorithm led you there. Again, this is how the algorithm was described by an ex-youtube employee, not just a casual user.
