On the other hand, the only platform that provides me with good recommendations to watch things seems to be TikTok. They are not asking me to rate individual videos, and so on. Clearly, there is a way to do recommendations without "ratings".

TikTok has two advantages:

- lots of short content

- viewing metrics to the second

Within an hour of usage you could've browsed through hundreds of TikToks, and allowed them to classify many tastes for you.

You'd need to sit in front of Netflix for an entire month for them to get the same amount of signal.
