Testing and proof are complementary. Testing, including property-based testing and fuzzing, is powerful: it catches bugs quickly, cheaply, and often in surprising ways. But testing provides confidence. Proof provides a guarantee. The difference matters, and it is hard to quantify how high the confidence from testing actually is. Software can be accompanied by proofs of its correctness, proofs that a machine checks mechanically, with no room for error. When AI makes proof cheap, it becomes the stronger path: one proof covers every possible input, every edge case, every interleaving. A verified cryptographic library is not better engineering. It is a mathematical guarantee.
For the uninitiated, the Pocket isn't an emulation machine. It plays actual Game Boy, Game Boy Color and Game Boy Advance cartridges. It also integrates with various Game Boy accessories, like the camera and printer. The console can even handle Game Gear, TurboGrafx-16 and Atari Lynx games, but those require separate adapters.
