Microsoft and major PC makers this week announced a plan to incorporate artificial intelligence directly into personal computers, adding on-board neural processing units (NPUs) as part of a new architecture that promises better performance, longer battery life, and local AI processing that unlocks new capabilities and features. We discuss the new Copilot+ PCs with our guest on this week's GeekWire Podcast, Stefan Weitz, an investor and entrepreneur who worked at Microsoft for 18 years in groups including Microsoft Bing and MSN. He is the founder of the new HumanX conference on AI taking place in March 2025 in Las Vegas. Weitz is bullish on the potential for Copilot+ PCs to improve the overall computing experience and motivate Windows PC users to upgrade their machines, a long-awaited milestone for Microsoft's flagship operating system. The new Copilot+ PCs have also raised security and privacy concerns, focused primarily on the "Recall" feature that takes regular screenshots of user activity on the machine, creating an index that can be queried using AI. The company released an FAQ that emphasized the underlying security and privacy controls for users, but also made it clear that the feature will be activated if users accept the defaults during initial bootup of a new machine. Weitz also shares some of his favorite AI apps and tools, including Cleft Notes and Read AI. Audio editing by Curt Milton. See omnystudio.com/listener for privacy information.
