AI 'writing' makes me ill, but that's happening because I can 'feel' the prose's samey hollowness in every paragraph.
But! If someone is just moving word by word and is focussed on just the gist (the average reading level is '6th grade' here in the states), then it will not repel them the way it does us. Also, AI's grammar is impeccable, if bizarre, and the word choices can be facially erudite, so that might also be mistaken as a signal for competence where none exists.
But I basically never use them for a blog post except maybe to include some boilerplate explanation of some technology. (Which I'm familiar with but don't want to rewrite or copy and paste.)
Could that change? Perhaps. But I don't really use today.
It's like how evolution taught humans that sugar indicates a good densely-packed food source, so then corporations just started putting sugar in everything and humans eat it as ravenously as they eat actual food.
