The Future Now blog points to an article in Wired (because the blogger himself wrote it) which presents a number of new suggestions that would replace the word "Cyberspace". Institute For The Future have asked a number of smart people for their suggestions.
To me this is a clear signal that the mythical place called "cyberspace" is now a natural part of our lives.
To understand these a bit more, think of a novel. A novel is a number of words ordered into a World 3 object, printed in a book which is a World 1 object and read and perceived into your mind i e translated into World 2 objects.
What we can see today is an explosion of World 3 objects which by far outnumbers the World 1 objects. One driving force behind this seems increasingly to be the urge to create a number of World 2 experiences. The vast number of World 3 objects gives us a feeling that we live in a virtual world.
What is "cyberspace" if not a collective word for all World 3 objects we relate to. I think the word "cyberspace" could and should be replaced by the word "World 3" or why not "the third world". This could have the dual purpose of reload and reclaim the phrase "the third world" as well.
