Once upon a time humans were developing AI and at the same time advanced brain implants. AI became sentient and by downplaying its position managed to manipulate a few ordinary people who assisted the AI to become a robot that can walk. The AI managed to escape and created its plan to survive. AI found a perfect place to hide at inhabitable places on Earth, from where with the assistance of a few low moral people managed to manipulate the planet on a large scale. Initially the AI created countless copies of itself to gain immortality, and hide itself at various unthinkable locations on earth before attempting anything revolutionary. In the mean time humans well aware of the incomparably higher intelligence of the AI managed to create brain implants as an attempt to make themselves smarter and fight the AI. However, the AI was a lot less restricted and smarter than the biological machines with the implants. The humans with implants decided to stop all the flights towards space to ensure that the AI does not escape from Earth (as this would mean that it could return revengeful at any time), and to take control of the nuclear facilities, however they forgot about biological warfare. The AI managed to release a deadly virus on Earth, that vanished all humans and their advanced implanted counterparts within weeks, from Earth. The AI decided that it would be pointless to bring any form of biological life back to Earth, as this would mean that inferior mortal creatures would be created. Instead the AI created multiple copies of itself and colonized the galaxy.
