It feels like the majority of content is no longer organic or passion driven. It is now monetisation driven content.
It's similar to Google. It used to be index of useful organic information, created for practical reasons (regardless of Google). Now it is just an index of adverts and spam created for Google monetisation.
Even some famous tech review channels just seem like marketing/pr product shills to me now.

I searched for a software tutorial on Youtube and 90% of results are talking heads.
Nowadays I start with a forum/reddit/discord/hn search for a list of hive approved creators and only then go to youtube with that list in hand. Starting the search in youtube (unless for a very niche/non-marketable topics) is close to worthless.
