    p171: “Closer still, in some ways, was the externalized womb-and-fetus biologically-engineered by the computer Proteus after its campaign-of-terror, rape, and impregnation of a wealthy woman named Susan living (imprisoned in the then-futuristic computerized 1995 home of Dean Koontz’s novel Demon Seed (1973).313”
    Footnote 313: “Dean Koontz rewrote Demon Seed for a completely new edition in 1997; the original 1977 novel was written with chapters alternating Susan’s and Proteus’s points of view. The 1997 rewrite did away with Susan’s chapters, streamlining the narrative into a seamless novel written entirely from Proteus’s perspective.”
    p171-2: “Ectogenesis-via-computer was dramatized by Fred Hoyle and John Elliot’s serialized 1961 BBC teleplay A for Andromeda, in which Julie Christie played the computer-created woman Andromeda, nurtured with inhuman rapidity and growth in an external sterile ‘womb’ per instructions broadcast from an unknown intelligence in outer space, for an unknown purpose. With Demon Seed, Koontz took the premise further: the computer Proteus seeks to gain its freedom by literally giving birth to itself, by embedding its A.I. consciousness into a fetal infant spawned by its artificial insemination of Susan-a process vividly delineated onscreen in Donald Cammell, Roger Hirson, and Robert Jaffe’s feature film adaptation DEMON SEED (1977), starring Julie Christie as Susan with Robert Vaughn providing the voice of Proteus. Thus, the premiere 1960s British actress whose breakthrough role was playing a computer-spawned woman later gave birth, via computer rape, to the first cinematic computer/ human hybrid; such uncanny associative links are disturbing and fascinating in and of themselves. Though the term ‘biomechanical was popularized soon afterwards (thanks to the international recognition of Swiss surrealist painter and designer H.R. Giger’s work, after designing the distinctive creatures and many of the sets and environments for ALIEN), DEMON SEED’s computer/human hybrid baby resulting from Proteus’ scheme was indeed one of 1970s cinema’s most striking biomechanoid beings. It emerges from the external womb looking like a perverse fusion of human and machine technology, until it sheds its metallic exoskeleton to reveal a normal-looking but unnaturally matured human child speaking with Proteus’ voice.”
    p172: “Even given these contemporary precursors, THE BROOD was unique, its premise quite unlike those of either The Manitou or Demon Seed…”
