Poems/ short stories on Negative impacts of Technology......
Ray Bradbury's The Martian Chronicles is a collection of short stories, many of which offer a strong critique against technology for technology's sake. One in particular, "There Will Come Soft Rains" tells the story of a house that is fully automated and still running, after atomic war. The inhabitants are long gone, but the house is still alive... Bradbury uses the house and its many gadgets (many of which are eerily similar to today!) to criticize humanity's over-dependence on technology.
One story that springs to mind is E.M. Forster's "The Machine Stops." It was written over a century ago, but is eerie in some of the ways it anticipates modern developments. It takes a very bleak view of technological progress.
Take a read through "Harrison Bergeron" by Kurt Vonnegut, Jr. The use of technology to allow for the creation of a society in which all citizens were truly equal, without advantages or handicaps to make one different from anyone else, is really frightening to those of us who think that individuality is a good thing.
The Little Lost Robot by Isaac Asimov (which was adapted to become the film I, Robot) shows the battle between humanity's hopes and fears for technology and the dilemma faced when humans are superceded by their own creation.
