In short: In Peter Watts's 2006 hard science fiction novel Blindsight, humanity encounters an alien presence that is terrifyingly brilliant yet completely devoid of self-awareness. This chilling premise challenges our most fundamental assumptions about the necessity of the ego and the true value of the human mind.

The story is set in a future where humanity has been alerted to extraterrestrial life by the 'Firefall'—a 2082 event where tens of thousands of unknown, comet-like 'Fireflies' burned through Earth's atmosphere in a precise grid. Following this, a crewed ship, the Theseus, is dispatched to investigate a radio signal originating from the comet Burns-Caulfield. The mission leads them to 'Big Ben', a sub-brown dwarf in the Oort cloud, where they encounter 'Rorschach', a massive, hollow vessel.

The crew discovers that Rorschach and its nine-legged 'Scrambler' inhabitants possess superhuman intelligence but lack any trace of consciousness or semantic understanding. While the vessel can learn human languages by eavesdropping, its linguist, Susan James, realizes it cannot actually parse linguistic ambiguities. This encounter serves as a profound exploration of the 'Chinese room' thought experiment, questioning whether intelligence requires an interior, subjective experience to be effective [S1:po27].

The novel's themes extend to the biological and the transhuman. The crew includes a genetically resurrected vampire from the Pleistocene, Jukka Sarasti, who possesses parallel processing capabilities. Through the eyes of the narrator, Siri Keeton—a man whose emotional life was severed by brain surgery—Watts explores the possibility that consciousness might actually be an evolutionary dead end: a resource-heavy luxury that offers no real Darwinian advantage in a universe of efficient, non-conscious predators.
