The issue is that the feed was too good. I ended up watching interesting stuff all the time. But it was also optimized to keep me hooked in a more pernicious way. If I were watching a mukbang video, it would end up recommending me hundreds of them. It's ok to watch one out of curiosity, it's awful when I realized that's all I had been doing for the last hour.

EDIT: I guess your experience could be different as I barely subscribed to any channel. I maybe ended up watching more shit because i'd be fully at the algorithm's mercy to decide what to shine into my eyeballs, rather than tuning it by actively telling it what i like. Be it what it may, my main goal with this is just to stop spending hours on end watching stuff on youtube.
