Famous quotes containing the word technology:

    Our technology forces us to live mythically, but we continue to think fragmentarily, and on single, separate planes.
    Marshall McLuhan (1911–1980)

    One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical precision that twice two is seven.
