Cyberspace

Gibsonian Cyberspace hasn't happened yet.  The direct neural interface is a pretty big barrier, although I understand people are working on it.  Everything still has to go through the retina.  Google Glass is the next phase of that.  Also, the idea that you could surf through cyberspace and see stacks of data, not the data itself, but that a certain company would have a certain sized stack and that different companies/entities have different sized stacks, is also something that any real version of cyberspace is not likely to reveal (because that is information just like the data itself). The internet is opaque to its users.  Not to hackers of course.
