Sociologically, things would be very interesting due to the rapid change in standards in the human condition in the last century alone. We'll still have issues of course, that's a given but when we do start populating other planets one has to wonder if there will be prejudice against people who grew up not on Earth.
Like Futurama predicted I'm sure that this will be known as the Stupid Ages due to the massive technological leaps and otherwise and our complete idiocy on how we've dealt with the planet as a whole.
