Until Google starts to expect better garbage from SEO providers. The bot can simply ask a language model if the page looks well written and truthful. So SEOs will have to spam us with well written useful articles about topics we like.

Maybe Google should require webmasters to mark the automated content with a special HTML tag or attribute. Failure to comply leading to deranking. This would be necessary for the future - to know what data was human generated when training the next model, and to have official reason for penalising spammers who try to pass artificial text as human written.
