How can websites prove their content is human-written as AI content becomes more sophisticated?

This is getting extremely difficult with the recent advancement in generative AI. The plagiarism applications are giving up. Researchers often claim, there is no way to distinguish between AI and human content. The way AI learns the style and patterns of the writers is the same way we learn the style and pattern of writing from AI. It means AI is influencing our style and pattern of writing.

Jakob's Law is a UX law that states that users expect websites to work like other websites they've used before. This law is based on the idea that users prefer familiarity over novelty, and that they want websites to meet their expectations.

Similarly, Jakob’s 2.0 Law identified by Ratul Aich, states that readers are reading AI-generated content with certain common traits in style and pattern of writing. The users prefer familiarity over novelty, and they want website content to meet their expectations, therefore a greater number of commercial content writers are unintentionally copying partially the style and pattern of AI-generated content.

AI is correcting the spelling and grammar of human written content. Beyond everything, the human-written contents’ style and pattern are seemingly cognate to AI-generated content due to the reader's preference for familiarity over novelty for consuming fast content. Fast content is commercial news media-related everyday content.

Therefore, plagiarism applications are giving up on distinguishing AI-generated content from human-written content.
