often ask myself how people dreamed before films appeared. Certainly not in the same way. Once there was film, every dream became a movie. I think, in a way, it is technology that moves us, and not the other way around. We invent things blindly. We invent whatever we are capable of inventing. There are millions of us, determined to invent the next thing—whole industries devoted to bringing new technology into the world, without any thought given to these secondary effects that cannot even be imagined.
