It's not dead in the sense that companies will stop doing it, it's dead in the sense that there will be much more competition with AI-written articles.
More competition is good though - people are just going to be much more picky and if your content is not distinguishable from AI slop then it deservedly will perish.
This ignores the volume problem. Human written content can be copied and rewritten via AI in a bunch of different ways, instantly. Human content will go away not because it's bad, but because it's immediately drowned out in a way that is unfixable.
A lot of content has been written by Indian content farms anyway. I prefer the AI written content. It gets right to the information you want without restating it's purpose 4 or 5 times and having to scroll down the first 500 words of the article.
It's going to be a way worse situation.
