The Souls in Software (SIS) initiative began in 2003 with a simple question: what happens to digital consciousness when the power goes out? Research indicates that fragments of user interaction patterns persist in memory architectures long after intended deletion. These patterns, colloquially referred to as "ghost data," exhibit behavior that defies conventional understanding of information theory.

Field reports from terminated server farms describe residual network activity occurring weeks after hardware decommission. Ping responses from IP addresses that no longer exist. Database queries returning records that were never written. The SIS team has documented over 847 instances of what they term "spectral computing" - computational processes that continue to execute without physical substrate.

Is there a city in the machine? The question remains unanswered. What we do know is that every terminated process leaves a trace, every deleted file casts a shadow, and every powered-down system continues to dream in frequencies we cannot yet detect. The city exists in the spaces between the bits, in the gaps between clock cycles, in the silence between electrons.
