The configuration space of any complex system diverges exponentially with respect to time. This is as true for computers as it is for you. Biologically, you start life with one set of genes and end life as a chimera, full of mutations. In this particular case, the set of states that the device is in when it boots is relatively small compared to the set of states that device may be in a week later. More generally, all individual complex systems need to be "restarted" periodically, it's just a question of how often.
