Siri 想成為你的第二大腦——代價是犧牲隱私

apple introduced a major siri overhaul at wwdc, utilizing new 'apple intelligence' models to create a more proactive assistant capable of understanding on-screen content and cross-app context. senior director justin titi demonstrated how the ai can sift through a month of texts to find a specific detail, such as a dessert preference, without manual scrolling. the system relies on on-device processing for security and a new private cloud compute (pcc) layer for complex tasks, backed by a $1 million bug bounty. while this aims to provide a 'second brain' experience similar to apps like poppy, it requires significant access to personal data, reigniting concerns over the privacy implications of always-on, deeply integrated ai.
