For lack of materials, due to the circumstance of being stuck on a train, I’ll try my best to summarize my specific points. The first point of “Speech Sounds,” the moment in which Rye is attempting to catch a bus to Pasadena, in which she mentions that the driver of the bus only runs a completely autonomous business out of his bus to feed him family. That moment in stark contrast to the moment that Deckard takes his hover car over to the Rosen association, seems to be suggesting the fact that without human communication, there can be no technological forward advancement. Even the disconnected and overly controlled, by mood organ, social interactions within Do Androids Dream of Electric Sheep? serve as enough communication to promote technological advancement within that world. I think Butler is suggesting that what was most important and what was taken away was people ability to communicate which is in turn their ability to cooperate and coexist. Therefore they could not advance.
