Video of the Day

High-tech hospital uses artificial intelligence in patient care submitted by Joseph Elsayyid.
Above is a brief but fascinating news story on AI in patient care—refreshing compared to the usual AI demos of "custom emojis" or "email summaries" no one asked for (cough cough Apple), and a great reminder of how AI development can truly improve lives.

I hereby solicit suggestions for the video of the day. Please email me your ideas with explanations. Selected entries will win 5 homework points. If your video is played at the beginning of class, you must also briefly explain something about the video and something about yourself - in person.

    Responsible AI in Global Business 2025 Unlocking Value, Earning Trust: A multidisciplinary conference at Yale

    AI is no longer a futuristic concept but a widely adopted technology shaping industries, governments, and everyday life. Unlocking its full potential requires a multi-stakeholder approach that balances the interests of consumers, employees, investors, and citizens. To foster this perspective, Yale is hosting a multidisciplinary AI conference, uniting leaders from business, academia, and government to navigate responsible AI development and adoption.

    The conference will explore AI from all critical angles—technology, management, societal impact, policy, and regulation. Participants will address key challenges, from building trust and securing social license in an AI-driven economy to meeting evolving regulatory needs. By convening diverse voices, the conference lays the groundwork for partnerships and strategies to unlock AI’s value responsibly.
