My post discussed two algorithms: the gating algo for CARA[0] and the search algorithm for YouTube.

If I'm reading your comment accurately, you're mentioning the discovery algorithm, which is neither of these. I also got the video, but I was already subscribed (it was suggested to me when it was released). Yes, the discovery algorithm has some of these issues but I'm more understanding of that because it's a much harder problem.

Both have self inflicted problems and I think they can be more easily addressed:

Discovery over optimizes to recent views and can get stuck in certain genres[1]. There is also a strong preference to things average user enjoys which doesn't work well for those of us who are only slightly less schizophrenic than the algorithm itself. Too much exploitation, not enough exploration (I wish this was a setting I could adjust. My mood changes, how can I let the algorithm know?)

Search has two critical self inflicted problems.

1) after about 5 results it will suggest completely unrelated videos (looks like it hands off to the discovery feed). Sometimes I need page two... just fucking show me more...

2) the problem I mentioned previously, where it distrusts you prioritizing popular videos over a trivial spelling or grammatical error. Google search has this exact same problem.

[0] my dumbass didn't check which video was linked. It's this one where he discusses it. At 12:30 in the video

[1] this leads me to having tons of YouTube tabs open as I'm unsure if a video I'm interested in but don't have the current bandwidth for is never going to be shown to me again

The quote in your intial reply ("It does make me wonder about the algorithm") was referring to the YouTube algorithm.
