I have pretty much the same amount of history with amazon (2000) and it's even worse here.

Most of the recommendations are items that I actually already purchased through them ("How about a second electric razor or some more batteries?") or items that I literally was just looking at while browsing ("We recommend these jeans that you just looked at"). Utterly useless.

It's hard to be worse than YouTube.

"Here are some videos you've already watched, mostly that you've already liked, but also a few from the same channel, and even a helping of some you've disliked but which other people have uploaded duplicates of."

And that's Google, the AI experts, with a crapload of data on my viewing and others' viewing habits, including in depth learning features such as length of time spent on videos, liked videos, playlists, etc.
