A Visionary Leader with a Humble Approach
Ternus is widely respected within Apple for his leadership style, which emphasizes collaboration and humility. In a 2024 commencement speech at the University of Pennsylvania’s engineering school, he shared a guiding principle:
Always assume you’re as smart as anyone else in the room, but never assume that you know as much as they do. With this mindset, you’ll find the confidence you need to push forward, but more importantly, the humility to ask questions.
