On February 11th 2026, the Harvard Club of Seattle hosted a session with Prof. David J. Malan, who discussed how CS50 has incorporated Artificial Intelligence (AI), including its new-and-improved rubber duck debugger, and how it has impacted the course already.
🦆 CS50 is Harvard University's introduction to the intellectual enterprises of computer science and the art of programming, freely available as OpenCourseWare, with more than 7M registrants at cs50.edx.org and 2.2M subscribers at YouTube.
In the session, Prof Malan covered:
• How do we approximate a 1:1 teacher-to-student ratio through software?
• How can we equip students with a subject-matter expert by their side at all times?
• How can we guide students toward solutions rather than offer solutions outright?
