That is very unsurprising for a languge model. It has no notion of "reality" outside of a probabilistic model of how text pieces fit together. It fooled you at

That is very unsurprising for a languge model. It has no notion of "reality" outside of a probabilistic model of how text pieces fit together. It fooled you at first because that is what it is designed to do, all of these look probable, as if they could be real. But the model has no notion of an actual scientific paper, which is connected to its author and which is published somewhere. The whole model is uniquely unfit as a search engine, it doesn't have a structured index of knowledge and information, where it could retrieve the data you want from. It will just make up stuff and it actually suceeded at its goal, which was creating a believable result.
