If that happens, I would like the "non AI" side to also not allow AI-generated content. (But how would that be enforced? I don't know.)
More generally: You could think about creating "sub HNs" for AI, politics, functional programming, startups, and several other categories. You could think about having something in your settings which specified which sub-HNs would put stories on your front page, with the default being "all".
