Nor is it encompassed by so many terabytes of code, video, imagery, text, and sound. I prefer to think of it as an organism composed of a variety of subsystems, each of which contributes to the overall health of the organism. In living creatures, the process of death is a collective collapse of all the constituent subsystems. Indeed, most deaths are attributable not to any single subsystem failure but rather to a collective synergistic failure of all the subsystems. As the kidneys grow weaker, the concentration of poisons in the blood increases, reducing overall system efficiency.
Metabolism slows down and the heart pumps less.
Appetite is reduced, thereby reducing the supply of nutrients with which to repair damaged cells. Resistance to infection falls, and opportunistic infections arise in the lungs. The creature grows lethargic, and in this lethargic state blood flow to limbs and musculature is reduced, further reducing recuperative capabilities in these regions. The whole system grinds downward towards a collapse. I believe that much the same thing is happening with computer games, although I do not anticipate a complete collapse of the organism.
