I mean, in my experience the people using LLMs aren’t validating. *I* am. They’re “saving time” by wasting mine. The close editing required is more time consuming and harder than writing something on your own. Which, of course, is why they don’t do it.
I wouldn't be surprised if those using LLMs without validating are the same ones who don't know how to write or do research in the first place. I've met far too many people who think AI apps are "magic" and believe not only what they tell them but assume they are omniscient and infallible.
Sure, that’s probably true. However, it is the LLMs making references to non-existent papers and jumbling numbers. These are mistakes different from human mistakes that cause wider problems.
