Posthuman

Robots are humans who transferred their consciousness into robotic shells which gave them a long time to understand how the universe works, leading them to evolve themselves beyond their physical limits, becoming Posthumans. (Alternatively, it could be said the robots are using their processing power to design better robots, these better robots then do the same and this cycle repeats until building the robots is going to take longer than designing them, at which point the robots are going to switch to a method which can quickly change form: Posthuman) Posthumans can answer every question in the universe, they can travel everywhere at anytime they want, simply by using their mind. Generally speaking, Posthumans have completely conquered their own universe, its physical laws, particles, matters, dark matters, dark energies; all taken by Posthumanity, making them a Type IV on the Kardashev scale. This is the final stage of human's evolution, the only way to go further is Ascension.
