However, as all of us have discovered, even though the basic technology of hypertext may be with us for centuries to come, perhaps even as long as the technology of the book, its hardware and software seem to be fragile and short-lived; whole new generations of equipment and programs arrive before we can finish reading the instructions of the old. Even as I write, Brown University's highly sophisticated Intermedia system, on which we have been writing our hypertext fictions, is being phased out because it is too expensive to maintain and incompatible with Apple's new operating-system software, System 7.0. A good portion of our last semester was spent transporting our documents from Intermedia to Storyspace (which Brown is now adopting) and adjusting to the new environment.
The author goes to marvel at simplicity of hypertext, then points out how long its course may run. He analyzes how the operating systems of hypertext are going to be outdated soon and that a cycle of updating and redesigning systems is necessary to keep it alive. Reading prior was done through pen and paper, which has not ever changed. Yet the way reading hypertext is done is not a constant vehicle that requires little maintenance. Online systems are well oiled supercars which can break down and become junk after enough time.
