Why would generative AI help stop enshittification? If anything AI has made low-effort slop far more common on the front page and sometimes it gets voted up because of a snappy headline and few people attempting to read it, particularly if long-form and initially convincing.
Information sharing networks with humans in it can only track so many things, or spend limited time on consumption. The more stuff on the network, the harder it is for things to be seen. The stuff that gets seen is content that is evolved to gain attention, or is resourced to gain attention.
This is as inevitable as sunrise.
