as to preserve the plants and animals in their natural ecosystems) on large fleets of interplanetary spaceships that will rocket outward into the solar system and convert all the matter they encounter into megacomputers made of computronium (such as Jupiter Brains) in order to continually expand the computer capacity of the solar system and thus create ever more realistic virtual reality and solve ever more complex computer problems. Once the matter of the solar system has been mostly converted to computer substrate, forming a Matrioshka brain, according to Kurzweil, by about the beginning of the 22nd century, life will then expand outward into interstellar space in all directions, deploying miniature starships (to save on expensive anti matter starship fuel) that will be Von Neumann probes crewed by swarms of nanobots, to colonize the entire Milky Way Galaxy. When these nanobots arrive in a planetary system, the nanobots will be programmed with software to begin converting some of the matter they encounter into more androids and robots. While in the process of doing so, they will continue converting all other matter they encounter not being used to create additional androids and robots into more megacomputers — the androids and robots created by the nanobots will build interplanetary spaceships to fan out into the planetary system and themselves help get this job done. Some of the androids and robots will then settle down in the meat world as immortal colonists on the surfaces of the Matrioshka brains thus constructed (regularly making backup copies of the contents of their brains so they can be reconstructed if they are killed in an accident), while others will upload themselves into the virtual reality based on these Matrioshka brains, keeping their bodies in cryonic storage. Eventually, the entire Galaxy, then the Local group, then the Virgo Supercluster, then the Pisces–Cetus Supercluster Complex and ultimately the entire Universe will be turned into a gigantic megacomputer. Artificial intelligence Superhuman is one of the stages in classification of progress in artificial intelligence where an entity of artificial intelligence performs better than most humans do in a specific task. Examples of where computers have achieved superhuman performance include Backgammon, Bridge, Chess, Reversi, Scrabble, Go and Jeopardy!. Anarchist philosophy It is suggested that there is a relationship between the fall of a society and the perfection of mankind. Many economic, social and environmental factors, which all contribute to the sustainability of
