Marshall McLuhan.

"Instead of tending towards a vast Alexandrian library the world has become a computer, an electronic brain, exactly as an infantile piece of science fiction. And as our senses have gone outside us, Big Brother goes inside. So, unless aware of this dynamic, we shall at once move into a phase of panic terrors, exactly befitting a small world of tribal drums, total interdependence, and superimposed co-existence. [...] Terror is the normal state of any oral society, for in it everything affects everything all the time. [...] In our long striving to recover for the Western world a unity of sensibility and of thought and feeling we have no more been prepared to accept the tribal consequences of such unity than we were ready for the fragmentation of the human psyche by print culture."
Note McLuhan's stress on the importance of awareness of a medium's cognitive effects. He argues that, if we are not vigilant to the effects of media's impact, the global village has the potential to become a place where totalitarianism and terror rule.
Key to McLuhan's argument is the idea that technology has no per se moral bent - it is a tool that profoundly shapes an individual's and, by extension, a society's self-conception and realization:
"Is it not obvious that there are always enough moral problems without also taking a moral stand on technological grounds? [...] Print is the extreme phase of alphabet culture that detribalizes or decollectivizes man in the first instance. Print raises the visual features of alphabet to highest intensity of definition. Thus print carries the individuating power of the phonetic alphabet much further than manuscript culture could ever do. Print is the technology of individualism. If men decided to modify this visual technology by an electric technology, individualism would also be modified. To raise a moral complaint about this is like cussing a buzz-saw for lopping off fingers. "But," someone says, "we didn't know it would happen." Yet even witlessness is not a moral issue. It is a problem, but not a moral problem; and it would be nice to clear away some of the moral fogs that surround our technologies. It would be good for morality."
