Futurama is set in the 4th millennium, the 31st century, as in 3000 A.D. and beyond. In Star Trek: The Next Generation, Picard meets a god, a being called Q who is one of my favorite characters and Q is from the future. I'm a big fan of science fiction. The future beyond the third millennium can give us hope or scare us half to death.
Will we be in Heaven or Hell in thousands of years from now? What do you think about transhumanism? Can we reincarnate or upload our brains into clouds and robots? What do you think about Star Wars and Battlestar Galactica? I don't even time right now to talk about other dimensions, let alone parallel universes and timelines.
