Out of sight, out of mind. How do we reconcile that with technology bringing the world closer, close enough for everyone to be within sight of everyone? When etiquette and freedom of speech collides in a world-size room from which no one can exit from, which should have the upperhand?
There are no clear answers to these questions but I think that people will choose to build private spaces within the 'room', spaces which appear to be pockets of tolerance when viewed from inside and pockets of intolerance when viewed from outside.
