I would also point to Ray Bradbury's stories as a great place to find commentary on social change as a result of technology. Many of his stories tend to glorify the past and villify the future, especially a future that emphasizes the value of technology.
His novel Fahrenheit 451is a classic example of a disutopia characterized by technology dependence and many of his short stories deal with similar issues.
The most obvious choices here are Ray Bradbury stories. "There Will Come Soft Rains" is a classic about how technology changes us. On the same subject, though less apocalyptic, is "The Pedestrian." In the first of these, technology actually destroys human life in a literal way while in the former it destroys it in a more figurative sense.
