I fundamentally disagree. I don’t think ‘people’ really do want that.
That reminds me of the thinking during the 90’s and early 00’s that everyone somehow must want 10 browser toolbars that spam them with ads all the time.
Well, that wasn't really about what they thought people wanted, it was about what toolbar makers thought could get away with (or trick people into). They wanted everyone to use their toolbar filled with ads. And some unsophisticated users ended up installing 10 different toolbars.
An example from the late 90s might be the idea that people wanted intro animations and music on web sites, heh.
As a user of both YouTube and Amazon.com I really don't want either recommendations you mentioned. I go to YouTube to watch specific videos and I go to Amazon to buy specific things. Those organizations want to give me recommendations but if I could turn them off and gain performance I would do that in a heartbeat.
