I don't think there is enough money, and only winners will be the good SEO people.
A new renaissance of slop content? Great, another boom in hiring and pay for web developers, followed by, oh look at that, a massive bust when it turns out that GenAI slop won't make any money, not enough to justify the engineering time in making and hosting it at least.
Actually, on the face of it, how can any of this work? Why would people (investors) believe that the general public is going to leave facebook, instagram, twitter etc to go look at https://sloppify.io in very large numbers? No, they're going to do exactly what is happening right now: fill social media with the genslop. So no, no building and maintaining website renaissance.
