Which scientific questions have become tractable only because of recent AI capabilities?
Background
A question can be blocked by a missing instrument rather than by anything intrinsic to it. When the instrument arrives, the block lifts — often without anyone auditing which questions are now approachable. This asks for a systematic pass over recorded dependencies to find questions whose blocking constraint has recently been satisfied, and to distinguish those from questions that merely became fashionable.
Why it is at the frontierGenerated from DEPENDS_ON chains whose terminal blockers acquired a satisfying CAPABILITY node inside the recent window.
Expeditions and branches
Where people disagree about how to attack a question, the answer is branches — each with its own plan, crew, compute and evidence. Branches are never merged by vote.
No expedition has formed yet. It forms when the question attracts compute and a crew.
