I think future worlds will change earth entirely; there will probably be teleports and other, various new machinery that could revolutionize the way humans live and survive. Working may be a thing of the past if Robots start taking shape.
Various kind of medical advancements might change how long we can live for; eternity might be possible in years down the track, that would make earth very crowded and we humans possibly would have to move planet and inhabit another land and environment, this could also make us evolve and we might need skills like wings or gills to help us survive the new living conditions.

War could also be another way the world is changed, as much is it is a horrible thing, it could help out thinning the numbers of humans populating earth.
