With the advancements of robotics, people would have the ability to create a robotic version of themselves by "uploading" their conscience (brain) to a robotic body.  By no longer residing in a carbon-based body, repairs and maintainance could be easily improved, leading to near immortality.

    Also, with intelligent robots at our command, humans could let robots do everything for them, giving people freedom from mundane or hazardous tasks, and creating more leisure time. Just think of "The Jetsons." Herro Reorge!
