Having work that can be edited by a human who understands the concepts –or at least the words— shows a great depth of usefulness to the work itself.
Running your rough draft in one language through an LLM so it appears, at surface glance, to be similar to a publication that a team of humans had been involved in doesn't actually provide value to the author or the reader. Now the author has a paper they cannot say they wrote (or indeed, say who wrote it) and the reader cannot assume that what they read was intended to mean what it now means in English.
If anything, people who write papers in another language to be published in English should be leaning more than ever on human editors and quality assurance measures, not slop machines that hallucinate with good grammar.
