It's funny. Roll back the time to about 2-3 years ago, YouTube's recommendation algorithm was terribly good. It's the only reason I still kept my YouTube account but every time I visit YT I feel less of a need to keep the account now.
As a mass YouTube users probably spend more time on the site if they can't find what they want; I get the impression this sort of thing happens a lot online now, string users along so you can feed them ads from your customers. I assume that's why they made Google search results so bad, rather than send you straight where you want to go they drive you around the block to run the meter up.
It seems to me that Google is expecting more from ML/AI than the tech is actually able to deliver. That is, of course, hardly a problem limited to Google.
