Something real has shifted. AI can now contribute to the work of discovery — proposing, modeling, testing, and reasoning over evidence, not just summarizing what’s already known. A careful, methodical effort aimed at the right question may now reach places that previously required a full lab and a decade — though that claim only holds when the work stays grounded and checkable.
The discipline is knowing where to point it. AI earns trust in exactly one place: where the work can be checked — against a measurement, a held-out outcome, an answer key that already exists. Aim it there and it is a genuine force multiplier. Aim it anywhere else and you get confident-sounding answers with no way to know they’re wrong, which in medicine is worse than nothing.
Neurodegeneration has those answer keys. Which mutations are pathogenic is measured in the lab, and much of that data is public. How fast a person declines is measured over time, against what actually happens. Because those answers are checkable, a careful effort can make real, accountable contributions to them now — not someday. That is the whole bet: aim high, but only where the evidence can keep you honest.
