I find stuff I like via the algorithm very often. Subscriptions cover channels that I want to see every upload of, but that doesn’t cover channels I don’t yet know about or channels only have a percentage of videos interesting to me. I use the algorithm mainly for finding content that I wouldn’t have discovered otherwise, and I can tell the algorithm knows to suggest me videos like that (low view/sub count videos show up for me way more than normal).
Yeah I can’t wait to use these glasses to replace my glasses.
