Thousands gathered at Microsoft’s Redmond headquarters for a demonstration of a new Excel feature that allows users to sum numbers with a click. The event celebrated Microsoft’s 50th anniversary and highlighted the AI assistant Copilot, which will receive new features for personalization, including remembering personal details, offering reminders, and task delegation. Microsoft is leveraging its technical groundwork to enhance its AI solutions, despite past challenges such as a 1998 antitrust lawsuit and competition from companies like Alphabet and OpenAI. CEO Satya Nadella emphasized the importance of innovation and collaboration for the future. The consumer version of Copilot is designed to have a “warm” personality, though it has been noted to be overly inquisitive at times.
