Electric technology changed everything about the human experience, McLuhan says. I'd never thought about it like that before. This movie, & the book of the same title, are wonderful & engaging. In our hypersaturated media environment, it bears repeating that mass media is a *very* new phenomenon. We, as a species, are just beginning to feel the genuine impacts of electric technologies. So even when McLuhan's personality gets pretentious, he still gave me a lot to think about.
