Except that a lot of our accumulated scientific knowledge is simply wrong due to experimental errors, fraud, selective publishing, and random false positives. See the whole reproducibility crisis.

It's conceivable that someone could construct a special-purpose AI which isn't superhuman but uses advanced ML and NLP algorithms to mine the scientific literature for previously unnoticed implications and relationships between seemingly unrelated articles. But I expect that would only give a suggested starting point for human researchers to formulate hypotheses and design experiments.
