Things go in cycle. Search engine was so much better at discovering linked websites. Then people play the SEO game, write bogus articles, cross link this and that, everyone got into writing. Everyone write the same cliches over and over, quality of search engine plumets. But then since we are regurgitating the same thought over and over again, why not automate it. Over time people will forget where the quality post comes up in the first place. e.g. LLM replaces stackoverflow replaces technical documentation. When the cost of production is dirt cheap, no one cares about quality. When enough is enough, people will start to curate a web of word of mouth of everything again.

What I typed above is extrememly broad stroking and lacking of nuances. But generally I think quality of online content will go to shit until people have had enough, then behaviour will swing to other side
