In the late 1860s, French Author Jules Verne predicted that, approximately 100 years into the future from his time, that the Americans would launch a space mission to the Moon, from Florida, employing a crew of three men, in a cone shaped spacecraft made of Aluminum, and would return to Earth using a heat shield plus parachute system, and be recovered at sea by the US Navy. He even predicted that the crew would experience weightlessness while en route.
Of course everyone at the time thought the whole thing was just so much nonsense, even scientists of the day.
I personally think the movie "Elysium" is an excellent model for our near future, except that the high tech, high prosperity society will develop on Mars, rather than in an orbiting habitat, as in the movie.
And I believe that in 500 years or so, we will have colonized several dozen other star systems, and then all humans will be required to leave Earth for good, allowing Earth to return to its former wild wilderness state. So after 500 years or so, there will be no humans on Earth any longer.
