Here in 2075, we usually sleep in the self-driving car of Tesla, and sometimes we use a self-flying plane, though it's mostly too expensive for generals. These modes of travel shape our daily lives.
Amid these advancements, our children are begging to travel by spaceship, dreaming even bigger than we do.
Inspired by these dreams, we feel motivated to make more money so we can eventually buy a dream house on Mars.
