I think the long term impact of this will be to strengthen the importance of social ties in academic publishing. As it is there are so many papers published in many fields that people tend to filter for papers published by big names and major institutions. But the inevitable torrent of AI slop will overwhelm anyone who is looking for any gems coming from outsiders. I suspect the net effect will be to make it even more important that you join a big name institution in order to be taken seriously.
