Well, that's terrifying. I mean, I knew it about undergrads, but I sure hoped people going into grad school would be aware of the dangers of making your main contact with research, where subtle details are important, through a known-distorting filter.
(I mean, I'd still be kinda terrified if you said that grad students first encounter papers through LLMs. But if it is the front end for all knowledge they consume? Absolutely dystopian.)
