The issue with AI slop isn't with how it's written. It's the fact that it's wrong, and that the author hasn't bothered to check it. If I read a post and find that it's nonsense I can guarantee that I won't be trusting that blog again. At some point there'll become a point where my belief in the accuracy of blogs in general is undermined to the point where I shift to only bothering with bloggers I already trust. That is when blogging dies, because new bloggers will find it impossible to find an audience (assuming people think as I do, which is a big assumption to be fair.)

AI has the power to completely undo all trust people have in content that's published online, and do even more damage than advertising, reviews, and spam have already done. Guarding against that is probably worthwhile.
