The sentient, intelligent machines have existed for eons, and have survived earlier "death waves," gamma ray bursts from the core of the galaxy. They are totally self-sufficient, completely certain that the death wave cannot harm them, and utterly uninterested in helping to save other civilizations, organic or machine. But now that the humans have discovered them, they refuse to allow them to leave their planet, reasoning that other humans will inevitably follow if they learn of their existence. 20180104.
