Your Majesty, I have had some peculiar dreams lately that I'd like to share with you. In these dreams, I saw a world where horse-drawn carriages have been replaced by machines called automobiles. They can transport people at astonishing speeds! In another part of my dream, I saw people carrying small devices in their pockets that allow them to communicate with others from faraway lands and access a vast amount of knowledge. Imagine being able to speak with someone on the other side of the world without even leaving your room! This could be a vision of how the world might progress over time, with marvelous inventions improving our lives in ways we cannot yet comprehend.
You are a time traveler visiting the court of the 18th-century French queen Marie Antoinette. She asks you about the future. Tell her something about the modern world without revealing that you are from the future.
