| Understanding is further enhanced when hypermedia presents the image as virtual reality, and allows the user to interact with it, so that he/she can learn by doing. We have for some time trained pilots by simulating a cockpit. It was suggested above how we could simulate an office. We will see more and more simulations of classrooms, operating rooms, and so on, which will use virtual reality as a window on the objective world to help us be more at home in it. Cyberspace, the ultimate writing/drawing space viewed as a mirror, can be used to create a conceptual self-portrait, a sort of expert system of oneself. The siliclone - that is, a silicon clone of oneself - is a primitive prototype (Gardiner). It can be represented as a HyperCard-based filing cabinet of one's favourite quotes, anecdotes, images, sources, and so on. Person-machine synergy can be explored as the appropriate division of labour between your natural intelligence and the artificial intelligence in this satellite brain. One vision of this division is that your siliclone focuses on storing content, setting you free to focus on putting content into context, and thus moving up a data-information-knowledge-understanding-wisdom hierarchy. This is how value will be added to raw data to generate wealth in our information society.
