In a later chapter, another Heywood Floyd, now a disembodied creature of pure consciousness, talks with Dave Bowman. It is revealed that the minilith duplicated Floyd's consciousness; there are now two Heywood Floyds, one an immortal being who resides with Bowman and HAL inside the Great Wall, another who will live and die without knowing this. Bowman shows Floyd images of his experience of studying the life forms of Jupiter before they were killed in the creation of Lucifer, explaining that the monolith weighed the Jovians against the Europans and decided the latter held more promise. Bowman states that during the diamond meteor impact, the immensely powerful monolith tipped over on its side, and may be damaged, And that he and HAL believe that when Lucifer begins to fail, the monolith will weigh the Europans against humanity, and they have only about a thousand years to prepare for that moment.
The script went through many stages. In early 1965, when backing was secured for the film, Clarke and Kubrick still had no firm idea of what would happen to Bowman after the Star Gate sequence. Initially all of Discovery ' s astronauts were to survive the journey; by October 3, Clarke and Kubrick had decided to leave Bowman the sole survivor and have him regress to infancy. By October 17, Kubrick had come up with what Clarke called a "wild idea of slightly fag robots who create a Victorian environment to put our heroes at their ease."  HAL 9000 was originally named Athena after the Greek goddess of wisdom and had a feminine voice and persona.
