Yet, it was an eight-year-old Indian gaming developer who wowed him with his vision of balancing technology and environmental sustainability.
Mumbai-based student, Medansh Mehta, presented his app Let There Be Light during a meeting between Nadella and student developers from India.
The boy left Nadella so impressed that the Microsoft CEO later mentioned him in a keynote speech.
His game Let there be light focuses on balancing development and the environment.
Players have to build cities by creating factories and farms, but also focus on the environment and air quality.
You are already ambitious beyond being the next CEO, Nadella replied.
