My point is actually that the problem space itself isn't solvable, not that someone other than Google will solve it. Google never solved how to win the game against SEO, and in recent years it seems they've either effectively lost or given up on it entirely. Generative tools make that much worse. Comparing content based on LLM summaries wouldn't really do the trick. For one thing, the LLM itself is a black box so we don't know how it works and could never measure or predict the accuracy or reliability. For another, when two pieces of content have a matching summary the only tie breaker would be publication date (or first seen date in the case of Google). That really doesn't definitively answer the question of which was LLM generated, and won't help at all for content that is originally generated by an LLM and won't match any known content. There's simply no way for an algorithm to accurately recognize computer generated content when the generation tools are good enough to mimic human content.
