Apple's WWDC: AI legacy at stake in Tim Cook's final conference as CEO

Apple heads into WWDC with its stock near record highs and iPhone momentum improving. The expected centerpiece of WWDC is a major overhaul of Siri, Apple's voice assistant. Analysts expect a more powerful Siri with a standalone chatbot-style app and deeper routing to outside models. Apple's AI strategy is a test of whether Apple Intelligence can become a real iPhone upgrade driver and justify its valuation.
