AI may matter most when it stops tuning experiments and starts inventing them

The author argues AI for Science is most consequential when it searches over experimental apparatus itself rather than tuning existing setups. Just 10 interferometry components yield over a billion possible topologies, far beyond human intuition.
- Key idea: start with an overcomplete experiment, deliberately including more components than necessary
- Optimization continuously adjusts each component's importance and physical parameters, evaluated via a physics simulator, then prunes what's unneeded
- Division of labor: physics predicts what an experiment would do; AI searches which experiment should exist
- This reframes experimental design from optimizing a known apparatus to searching over apparatus space — potentially more transformative than replacing scientific models
