I was thinking about that too.

I am probably being too optimistic, but wouldn't it solve the problem if peer-review had a pre-screening phase where you give a presentation about your work? Similarly to how a PhD presentation is given. It could give back the publishing power to the expert, rather than the journals.

Once you have validated that the knowledge you want to publish is yours and that you actually understand and own the work, then it doesn't matter if the paper is written by a LLM or if the LLM assisted you in doing the work.
