TBH I feel like this would damage the community/experience. Part of the "magic" is learning about a topic that you wouldn't normally be interested in, but which is presented in a particularly compelling, new, or original way such that it garners attention here. I like those moments.
Maybe you jest, but this is the future of the internet. Except instead of filtering by "is ai related" it will be able to "exclude by is-toxic, is political, is a whataboutism, etc"
Maybe. But that AI would have to know you, specifically, very well in order to understand what you consider toxic, political, etc.
Personally, I wouldn't want such a filter at all. It would exclude me being exposed to things outside of my comfort zone. I think that would be an unacceptable loss.
