I’m reading an old article by Oskar Negt, and what should be the epigraph but a prescient quote from Brecht’s Radio Theory (1927):
If I believed that our present bourgeoisie were going to live another hundred years, then I would be certain that it would continue to babble on for hundreds of years about the tremendous “possibilities” that the radio, for example, contains…. I really wish that this bourgeoisie would invent something else in addition to the radio — an invention that would make it possible to preserve everything the radio is capable of communicating for all time. Future generations would then have the opportunity to be astounded by the way a caste made it possible to say what it had to say to the entire planet earth and at the same time enabled the planet earth to see that it had nothing to say. A man who has something to say and finds no listeners is bad off. Even worse off are listeners who can’t find anyone with something to say to them.
I daresay he has just described Twitter.
