In plain words: A language agent that reads scientific papers and writes cited, Wikipedia-style summaries was tested head-to-head against human experts on real literature search, summarizing, and contradiction-spotting tasks. It matched or beat the experts, even though they had unlimited internet access and time.
Abstract
Language models are known to hallucinate incorrect information, and it is unclear if they are sufficiently accurate and reliable for use in scientific research. We developed a rigorous human-AI comparison methodology to evaluate language model agents on real-world literature search tasks covering information retrieval, summarization, and contradiction detection tasks. We show that PaperQA2, a frontier language model agent optimized for improved factuality, matches or exceeds subject matter expert performance on three realistic literature research tasks without any restrictions on humans (i.e., full access to internet, search tools, and time). PaperQA2 writes cited, Wikipedia-style summaries of scientific topics that are significantly more accurate than existing, human-written Wikipedia articles. We also introduce a hard benchmark for scientific literature research called LitQA2 that guided design of PaperQA2, leading to it exceeding human performance. Finally, we apply PaperQA2 to identify contradictions within the scientific literature, an important scientific task that is challenging for humans. PaperQA2 identifies 2.34 +/- 1.99 contradictions per paper in a random subset of biology papers, of which 70% are validated by human experts. These results demonstrate that language model agents are now capable of exceeding domain experts across meaningful tasks on scientific literature.

Train on all published scientific knowledge and observations up to certain point, before a breakthrough occurred. Then see if your AI can generate the breakthrough on its own.
For example, prior to 1900 quantum theory did not exist. Given what we knew then, could AI reproduce the ideas of Planck, Einstein, Bohr etc?
If not, then AI will never be useful for generating scientific theory.
