Dave Plummer, a former Microsoft software engineer, has expressed concerns about Windows 11's direction, advocating for a focus on stabilizing and enhancing performance rather than adding new features, particularly AI-related ones. He compares the current situation to the response to the Blaster worm in 2003, when Microsoft halted feature development to address security vulnerabilities and bugs. Plummer believes Microsoft should prioritize improving Windows 11's performance and usability for power users before introducing new features. He notes that the current emphasis on AI capabilities may detract from addressing core functionalities and that shareholder value seems prioritized over user experience. There is a call for Microsoft to refine Windows 11's underlying code and resolve performance issues, although the feasibility of pausing feature development for an entire release cycle is questioned.
