I would rather be fluent in all languages because it would allow me to communicate effortlessly with people from different cultures, opening doors to new opportunities, relationships, and experiences. Breaking language barriers would make it easier to understand diverse perspectives, travel freely, and access knowledge without limitations.
Fluency in every language would also be incredibly valuable in both personal and professional settings, making interactions more meaningful and enriching. While understanding animals would be interesting, the ability to connect with anyone around the world would have a much greater impact on my life and society as a whole.
