I found the feed with it enabled is much better than disabled and I have it finetuned to be more in line with the niches I care about.
I am also very proactive with marking channels or content I don't prefer with the "Not interested" or "Don't recommend channel" as well as going through and pruning any content I don't want from my watch history directly.
It's not perfect but it's orders of magnitude better than my logged out or watch history disabled account (though not sure if they have since updated it to not show anything at all)
Youtube actually works reasonably well, as long as you remove from history content you disliked, use do not recommend channel and possibly not interested option. It might not be highest of quality, but at least content stream then is passable.
I follow N YouTubers who produce genuinely useful and insightful videos on the state of the market and personal finance etc, but the algorithm just recommends people with stock tips and scaremongering junk
It's deliberate, I'm sure. People say they want the vegetables, but then go on to watch hours of fast food / Shorts. Clearly the algorithm knows.
People are addicted to YouTube but I think the key to the healthy watching habits would be restricting the screen time.
Someone knowing about things he's interested in has few problems separating the new and informative content and if he had, say, two hours a week for watching he'd probably enjoy what he sees.
Two hours is just an estimate I came up with, it can be an two hours a month or hour a day. The important thing is that YT just doesn't create enough real new information and after that it is just slop and brain rot, regardless of your habits and filters.
Though, new AI-slop channels popup some days - esp. new/fresh channels, but these you can ban anyway since most new channels are AI slop. or "XY ... official" or "XY .. best of" or "XY .. clips" or "XY... fails"
If you somehow curate your YT account, the shit wont show up anymore (only new shit not banned already) and you will see one thing: A curated youtube feed is actually rather empty :-D
On some days, I really have to actually look precisely if there is something new at all: Im a subscriber of 30-35 technical/business channels - its very rare that i could "spend a whole day watching YT", because there is just not enough new stuff.
Before curating my account, I also had the impression that "its endless and not any sort of structure" - but it has.
