I've found that I only watch less Youtube over the years as their suggestions got worse for me. Now I feel like I only ever see a handful of the same suggested videos and they are all from years ago.
I would like to be able to watch more YouTube videos, but their recommendations are so bad at this point that I have to find other things to do.
I'm interested in psychology and philosophy, so I'll watch videos on those subjects every so often. Naturally, the Algorithm™ becomes obsessed with recommending me Peterson videos soon after. I'm 98% sure the "Do not recommend" and "Not interested" buttons are just there for show, because I keep seeing those suggestions whenever I wander off into psychology and philosophy videos.
