Technologies may become obsolete with the advent of other technologies or social changes. I think Bruno Latour makes an important point here in stressing that human and non-human (technologies) should be thought of as one. So, a technological change might go hand in hand with a social one. I don't think it has to be a disaster though. This isn't really an undo but rather the result of some pruning when an obsolete tech isn't economically viable any more.
