Genesis is science fiction but realistic. How?
Science fiction is defined as
a genre of fiction dealing with imaginary but more or less plausible (or at least non-supernatural) content such as future settings, futuristic science and technology, space travel, aliens, and paranormal abilities.
Genesis is a fictional work that fits many aspects of this definition.
Set in the late twenty-first century, the plot takes place in the future in a society that had been developed in response to economic and political turmoil and environmental destruction in the world as a whole. These concerns and consequences are plausible in our world today.
The androids in Genesis are fictional at this time; with the advances in artificial intelligence and robotics that are under way, that quite possibly may change in the future. This is a plausible presentation of the developments in science and technology that the future may produce.
While there are no aliens or paranormal events in the usual sense in the story, the androids assume some of the traits and roles of other-worldly creatures coming to invade and control the Earth.
