In the future, man has colonized the solar system but is dying out. Human existence is free of difficulty, as all illness and predators have been eliminated, and all work is done by perfect machines. However, almost all other living species have been made extinct by the advancement of man; the oceans are empty of any life-forms altogether, all other mammals, as well as birds, lizards, insects and microbes, have been eradicated and even traditional pets are gone for good. Only some plant-life still exists - and machines who blindly follow orders given by the previous generations of humans. Humans, though highly intelligent, have totally lost their curiosity, drive, and much of their knowledge. As a result, they have accomplished nothing new in about two million years. They are, as things then stand, a dying race, which retreats from the outskirts of the solar system back to earth, abandoned most of the mega-cities (such as "Yawk City" = a megalopolis, stretching from north of Boston to south of Washington DC) and hardly reproduce anymore. All they are able to do is stare at their remote ancestors' achievements, while comprehending none of them.
But the machines just go on; each of the long-deserted cities keeps running perfectly, as if nothing has changed. Cities, where human foot has not stood for hundreds of thousands of years, are still cared for by the machines, who never stopped supplying the city all its human needs, because no one has ever told them to stop; no human of that time can remember how.
Highly intelligent machines capable of independent thought had previously existed, but were shut off for an unknown reason. No human alive knows of their prior existence any more, aside from the traveller. To try and ensure that there remains something that can strive and evolve on Earth, he orders several of the remaining machines to figure out how to recreate a curious, thinking machine, even if it takes millions of years.
