Honestly, I don't think that's as crazy as it sounds. AI/ML-driven feeds often promise more than they actually deliver and by now more and more people are starting to realize that AI/ML is not the holy grail it was made out to be, at least in situation where you cannot throw massive resources at the problem.
Maybe not exactly in the form of webrings, but who knows, why wouldn't it be time for the pendulum to swing from the whole AI hype back in the other direction? There is a lot to be said for conscious curation on your terms and your devices vs algorithmic decisions made in the cloud for you.
I'm calling it now, the hottest startups will be "disrupting search using artisinally crafted rings of websites"!
