AI in science & discovery
Where machine learning has genuinely changed how research gets done, described by the method and by the verification step that still has to happen.
There is a version of this subject that is a list of breakthroughs, and it is almost useless. Breakthrough lists go stale, they compress a prediction and an experiment into one sentence, and they give a reader no way to judge the next claim they encounter. This cluster is built the other way round: each page describes a problem that was intractable, the thing a model actually computes, and who has to check the answer before it counts as knowledge.
That last part is the load-bearing one. A model does not confirm anything. It produces a hypothesis — a structure, a candidate compound, a forecast, a classification — and somewhere downstream a crystallographer, a chemist, a clinician or a proof checker either accepts it or does not. Where that downstream step is fast and cheap, machine learning has transformed a field. Where it is slow and expensive, the field looks much the same as it did, no matter how good the predictions have become. Most of what is confusing about AI in science is explained by that one ratio.
