Or we're going the roundabout way towards it. First perfect the art of indoor culture, then send the thousand year traveling seedships (and not have them collapse under a massive psychological problem). First de-sensitize humans as a species to survive inside artificial cubes, to be culturally indoctrinated to communication and co-ordination through tiny screens - then, when the entire planet is basically psychologically fit to survive inside sealed containers doing nothing but eating processed foodstuffs and play multiplayer online games for a thousand generations then pack the hardiest of them inside containers and chug the towards the nearest star with an earth like world.
