I think that’s a great possible topic.
An as example, my daughter is an environmental science major. She answered the PIQ about a favorite subject and wrote about learning foreign languages - NOTHING to do with her major or anticipated future career at all. She answered the “talent” PIQ about various times she taught skills to others - again, NOTHING to do with her major or career aspirations. But it showed her breadth.
One PIQ about your major is enough. Use the other PIQs to set yourself apart from every other - and there are THOUSANDS - of CS applicants. Show how you are unique and stand out from the crowd with your talents and interests.
