World of Tomorrow

A young girl named Emily Prime is contacted by a third-generation clone of herself from 227 years in the future, created as a means of achieving immortality. The clone explains the myriad ways people in her time have sought to escape death and loneliness through technology before embarking on a mind-bending tour of her distant future. They travel to the clone's time and visit the Outernet, a future version of the Internet, where they explore memories of the clone's life, including an art exhibit featuring a male clone without a brain, nicknamed "David", and experiences with Emily's various jobs and love interests on the Moon and in outer space. The clone Emily ultimately reveals that in 60 days, Earth will be destroyed by a meteoroid, leaving her with only one cherished memory to hold onto before her own impending death.
