In the last of a three-part series, William Woollard asks where our species goes from here. According to some, nowhere; technological animals cannot evolve. But as we face the dawn of machine intelligence and the possibility of reproducing robot rocket ships, how much of the running of the world will be left to men? Intelligence it appears, has a long way to go yet. But where will it stray? To interstellar dust clouds? To the interiors of suns?
