Facebook has subsumed the roles held in earlier eras by the telephone, the newspaper, the tavern and the public square. Never in our history has there been such singular envelopment of the public forum under the control of a single commercially motivated entity. Here in the states Ma Bell and the big oil trusts were broken up for less pervasive consolidation of power.
What does the better alternative look like at at this stage? Going to another extreme - what outcomes might a completely autonomous decentralized non-owned user-controlled network produce? I’d venture that some of the most destructive aspects of facebook are to be due to (for lack of better descriptors) harmonizing and context-flattening characteristics of the medium. Could we design a comms channel that fulfills the functions that our current technologies promise totally absent of structural institutional manipulation - (and if so what would the societal effects look like?) Personally I don’t know, but I would be very keen to find out.
