To duplicate my consciousness, or transfer it to another location, I will need to know how to reproduce the biological hardware of my brain and spinal cord, as well as the mental software containing my memories, sensations, emotions, and thoughts. In the meantime, it might be best to forget about running the same software on many pieces of hardware and focus instead upon the converse idea of running multiple software programs at once on a single piece of hardware. Why worry about transporting myself into another body when I still haven’t realized how many different selves are present in this body that I already have? People with Multiple Personality Syndrome are said to display different physiological patterns—different voices, different pulse rates, even different levels of cholesterol—depending on which personality is in the forefront at a given moment. Thus the same actual body can support many different virtual selves.
