What if the greatest tools for solving complex problems weren’t found in labs or textbooks, but in the words we speak every day? Growing up bilingual, I learned that language is more than communication. It’s a way of seeing the world. Translating for my grandmother as a child, I discovered that every word carries shades of meaning, and that waiting in the space of uncertainty often reveals deeper truths. This practice of patience and perspective would later shape how I approach science and research. Studies confirm what many bilinguals experience firsthand: switching between languages rewires the brain. It builds cognitive flexibility, sharpens critical thinking, and even reduces decision-making biases. Beyond cognition, bilingualism strengthens empathy by training us to navigate multiple cultural frameworks, helping us understand others with nuance and compassion. But this ability is fragile. Every two weeks, a language disappears, and with it vanishes a unique blueprint for problem-solving, healing, and human connection. In this talk, I share how embracing and preserving languages can spark creativity, fuel diplomacy, and even safeguard knowledge vital for our future. The courage to learn, preserve, and speak each other’s languages may just be the key to uniting us all.
