The novel Prey by Michael Crichton follows a computer programmer through a modern science fiction world filled with corporations obsessed with nanotechnology and artificial life.
The main plot points of the novel focus around a swarm technology that has developed evolving intelligence and independence from its creators – ultimately a lethal, unstoppable, manufactured force of nature.
The biggest reveal at the end of the novel is that another "strain" of the swarm had infected many of the characters - surrounding them in an artificial "skin" and, presumably, driving their actions?
My questions are, ultimately: How does the swarm in Prey by Michael Crichton actually infect the various characters that host it? How does it go about controlling them, and what is its goal?
I, frankly, just don't understand this whole "infection" concept.
The counter-measures Crichton suggests (curing Amanda with an MRI scan, simply spraying the infected with a solution of water and phage for instant swarm destruction??) don't help to form an understanding.
