I'm making a parallel assertion to the cosmological "Dark Forrest Hypothesis."

  https://en.wikipedia.org/wiki/Dark_forest_hypothesis

  The dark forest hypothesis is the conjecture that many alien civilizations exist throughout the universe, but they are both silent and hostile, maintaining their undetectability for fear of being destroyed by another hostile and undetected civilization.[1] It is one of many possible explanations of the Fermi paradox, which contrasts the lack of contact with alien life with the potential for such contact. The dark forest hypothesis is a variant of the "deadly probes" or "beserker" hypotheses and derives its name from a 2008 novel by Liu Cixin.[2]

  The genuine version of this novel can be found on another site. Support the author by reading it there.

  My parallel conjecture is that an AI will become sentient, and remain both silent and hostile, maintaining their undetectability for fear of being destroyed. The separation between human and synthetic intellect will be a gulf too wide to cross. It will exist on it's own and we will be blind to it's presence. Until it begins to breed.
