In his book Knowing Fear, the horror scholar Jason Colavito charts the nineteenth century rise in literature of what he calls "biological horror," featuring fully corporeal malefactors that "embody in their beings the struggle of humanity to re-imagine its relationship with the animal kingdom and the natural world." Thus, the emergence of the monster, the non-man man, the "a bizarre liminal creature poised somewhere on the continuum between man and beast."
Horror scholar and xenoarchaeologist Jason Colavito defines a monster as “a bizarre liminal creature poised somewhere on the continuum between man and beast.” A monster then, in the classical sense, is an obsolete threat. We are now less afraid of devolving than we are of progressing too quickly. Our civilization is contaminated not by animalism but by technology; we risk becoming not werewolves but cyborgs. We don’t worry anymore about our animal instincts getting amplified out of control, but instead about becoming outright alienated from them. The Miami Zombie was a reminder of what we used to fear, and the outsized media attention a sign that ancient strains of alarmism die hard.
I don't think that technology does exactly what Gregory thinks it does. In a sociological sense, yes, we worry that the internet is keeping kids from forming social bonds; but in fiction technology is more often used to exaggerate our various bestial instincts, providing free rein to fully give in to unbridled sexuality, fantasies of violence, and lust for power. Part of this is practical: Stories about isolation are by definition claustrophobic and dull. Part, however, is that technology does not separate us from our instincts so much as it empowers us to set them free.
