PHYSIX OBSERVATION

The Apple-Meta handshake is an exchange of interests under AI anxiety: Apple lacks a model, Meta lacks an entry point. The story of running large models locally strengthens Apple's privacy narrative and also warms up demand for high-priced hardware. But Meta's trust deficit has not disappeared, and whether the partnership can last remains doubtful.
