Luckily the same AI tools that are generating the content can be used to build better tailored discriminators for it as well. If I can define what it is I dislike about an essay, video, etc., and give it to an LLM, it can tell me whether a piece I present to it is worthwhile to consume according to my standards. This even applies to things the LLM can't generate things for that meet the same standard for its programmed/prompted discrimination.
Yeah works out great for HR departments and job hunters.
Assuming that the LLM search will be meaningfully better at cutting through bullshit than the generating model was at avoiding creating it is, charitably, dubious. Assuming that it won’t be every bit as gamable as Google results is as or more dubious.
