> Over time the gems will rise to the top

I’m not sure this can be assumed. Discovery was already one of the biggest hurdles when releases were bottlenecked by human output. Increasing output 10x is only going to make it worse.

Same as with Google, where they’ve lost the SEO war against AI spammers and valuable content has become close to impossible to find.

while SEO has made search worse, i don't think it's the core reason why things are impossible to find, i think it's simply the fact that, over time, google has been butchering the ability to search for exact terms in favour of "natural language" searching, which makes simple things like "how do i make an orange cake" or whatever return useful results, but makes any actually technical query return a lot of pure garbage
