Filter bubbles are one of the bad side effects of social medias. You see a youtube videos and you enter the rabbit hole: a world of youtube videos sharing the same "ideology" and creating a world totally different to what other people close to you see. You can't agree on anything since you are part of two bubbles - different storytellings of the world - and none of you sees anything else than that bubble.
In the meanwhile, YT says they're not responsible of published content such as a newspaper is, since they leave users free to publish. I agree with this position but while they don't moderate, they do suggest content. I'd say that if you're suggesting what to see next, you're responsible of that suggestion.<p>So I'd say, what if YT (and al the others) could only suggest videos ranking next from the search which you performed and/or from the same youtube channel? Within a same channel, the publisher is responsible.<p>This way they keep you in the path you were, without targeting you with catchy videos to keep you engaged
