summary
Prototypes cost time and hide domain depth; after a couple of years of daily practice the claim is to stop building full UI mocks and instead run domain model experiments that exercise invariants, commands and events. The talk shows replacing end-to-end prototypes with small model-driven scenarios, uses code-level examples and quick property checks to reveal boundaries and inconsistencies early, reports faster feedback loops and fewer wasted UIs, and demonstrates the approach works on real projects rather than thought experiments.
