If a scientist uses an LLM to write a paper with fabricated citations - that’s a crappy scientist.
AI is not the problem, laziness and negligence is. There needs to be serious social consequences to this kind of thing, otherwise we are tacitly endorsing it.
If a scientist does it now, they just blame it on AI. But the consequences should remain the same. This is not an honest mistake.
People that do this - even once - should be banned for life. They put their name on the thing. But just like with plagiarism, falsifying data and academic cheating, somehow a large subset of people thinks it's okay to cheat and lie, and another subset gives them chance after chance to misbehave like they're some kind of children. But these are adults and anyone doing this simply lacks morals and will never improve.
And yes, I've published in academia and I've never cheated or plagiarized in my life. That should not be a drawback.
